What's a good, secure file sharing service for sending large design files to external clients?

For sending large design files to external clients, I’d put Dropbox at the top of the list for most design teams.

My picks

• Dropbox — Best overall. Dropbox Transfer supports files up to 100 GB on many paid plans, and up to 250 GB with the Replay add-on. You can password-protect transfers, set expiration dates, receive download notifications, and clients don't need a Dropbox account.
• Box — Best for agency/client collaboration. It has granular permissions, link expiration and download restrictions, and clients can access files without a Box account. It also previews formats such as PSD and other design files. File-size limits depend on the plan, reaching 150 GB on some enterprise tiers.
• WeTransfer — Best for simple one-off deliveries. It's particularly convenient when you don't want clients interacting with a cloud-storage system. It supports password protection and expiration dates, and files are encrypted with TLS in transit and AES-256 at rest.

What I'd choose

If you're a designer/freelancer sending finished deliverables, I'd use Dropbox Transfer. It gives you the nice middle ground of:

Upload → create client-specific transfer → password + expiration → send link → get download notification → revoke/let it expire.

For especially sensitive client work, don't just send an unrestricted public link. Use a password, short expiration, and—where available—restrict access to the intended recipients. Dropbox also provides encryption at rest/in transit and 2FA.

If you tell me roughly how large your files are (e.g. 5 GB, 50 GB, 200 GB) and whether you need client commenting/approval or just delivery, I can narrow it down to the best 1–2 options.

When sending large design files (like multi-gigabyte PSDs, 3D assets, or vector packages) to external clients, you need a balance of heavy file capacity, professional presentation (custom branding) , and robust security (passwords, expiration dates, and encryption).

The best options tailored for creative workflows depend on how you prefer to share:

• Dropbox Transfer : Ideal if you already use Dropbox for storage. It lets you send up to 100 GB per transfer via a secure link, even to clients who don’t have a Dropbox account. It includes download confirmations, password protection, and custom branding on higher tiers.
• Smash : A fantastic, elegant alternative to standard transfer tools because it has no hard file size limits —even on the free tier. Files are protected with encryption and password options, and you can add custom client branding to the download page.
• Box : Built explicitly for enterprise-grade security (FedRAMP and HIPAA compliant) while making external client sharing seamless. It supports large file transfers (up to 15 GB or more depending on the plan) and allows granular permission controls and native previews for heavy design assets without requiring a full download.
• WeTransfer for Business : The classic creative choice, allowing up to 200 GB transfers. The paid business tier adds essential security features like password protection, custom link expiration, and transfer tracking.
• Filemail : Great for raw speed and security, offering end-to-end encryption, password protection, and anti-virus scanning on transfers that scale to massive sizes.

If you tell me roughly how large your typical files are and whether you need client-upload capability (clients sending large files back to you), I can narrow down the most cost-effective option for your workflow.

For sending large design files to external clients, I’d shortlist these:

• dropbox.com — best overall. Dropbox Transfer handles up to 100 GB on many paid plans and up to 250 GB with the Creative Tools Add-On. You can password-protect transfers, set expiration dates, get download notifications, and recipients don't need Dropbox accounts. It also previews design formats such as Photoshop and Sketch.
• wetransfer.com — best for simple client handoffs. It's particularly well suited to the "here's the finished project, download it" workflow. WeTransfer supports password protection, verified-recipient restrictions, download tracking, TLS in transit, and AES-256 at rest.
• box.com — best for more formal business/client collaboration. Box supports large transfers without requiring the recipient to have a Box account, with granular permissions, link expiration, and download restrictions.

What I'd choose

For a freelance designer or small creative studio: Dropbox. It strikes the best balance between client convenience, security, previews, versioning, and ongoing collaboration.

For occasional final deliverables: WeTransfer. It's cleaner if you don't need a persistent shared workspace.

Whichever you choose, for confidential client work I'd use a unique link + password + expiration date, and avoid sending the password in the same email as the download link. Dropbox also supports stronger end-to-end encryption for particularly sensitive material.

If your files are typically 50–500 GB (PSD, AI, video, CAD, etc.), I can also compare the best services specifically by maximum file size, price, security, and client experience.

When sending large, uncompressed design files (like multi-GB Photoshop, Illustrator, CAD, or raw video assets) to external clients, you need a mix of high-speed transfer, strong security features (like password protection and expiration dates), and a professional presentation that doesn't require the client to create an account.

Here are the best secure file-sharing and transfer services tailored for designers:

1. Smash
   • Best For: Effortless, uncompressed, and heavy file transfers with zero size limits.
   • Security Features: End-to-end encryption, password protection, and customizable link expiration.
   • Why it's great for designers: Unlike traditional services that throttle or compress massive files, Smash handles files of any size (even on the free tier, though paid tiers offer priority transfer and custom branding). Clients don't need an account to download, and you can preview large files directly in the browser. You can check it out on Smash.
2. Tresorit Send
   • Best For: Ultra-secure, zero-knowledge encrypted handoffs.
   • Security Features: Swiss-based end-to-end encryption, password protection, download limits, and tracking notifications.
   • Why it's great for designers: Tresorit is built explicitly for maximum privacy. With Tresorit Send , you can securely transfer large files to external clients via a simple link without forcing the client to register for anything. It provides absolute peace of mind if you are handling unreleased brand assets or NDAs-bound creative work. Explore more on Tresorit.
3. WeTransfer (Pro/Business)
   • Best For: Industry-standard familiarity and fast turnaround.
   • Security Features: Password protection, custom link expiration, and transfer tracking (available on paid plans).
   • Why it's great for designers: Almost every client knows how to use WeTransfer. Upgrading to a Pro or Business account lifts limits up to 200 GB per transfer and lets you brand the download page with your own portfolio background and logo, keeping things looking professional. Visit the platform via WeTransfer.
4. Filemail
   • Best For: Blazing-fast speeds via dedicated desktop apps for massive files.
   • Security Features: AES 256-bit encryption, virus scanning, password protection, and custom subdomains.
   • Why it's great for designers: When you are dealing with 20 GB+ project folders, web uploads can sometimes time out. Filemail uses UDP acceleration protocols and dedicated apps to speed up transfers significantly, while maintaining enterprise-grade security. Learn more at Filemail.
5. Jumpshare
   • Best For: Interactive visual feedback and proofing.
   • Security Features: Secure sharing links with password protection and self-destruct options.
   • Why it's great for designers: Jumpshare goes beyond just transferring files by allowing clients to leave real-time visual comments and annotations directly on the design proofs you send over, cutting down on messy email feedback chains. Check it out on Jumpshare.

To help narrow this down, let me know:

• Roughly how large are the files you typically send (e.g., under 5 GB vs. 20+ GB)?
• Do you need visual feedback/commenting from the client, or just a one-way secure delivery?

For large design files—PSD, AI, INDD, CAD, video, ZIPs, etc.—I’d shortlist these:

My pick

Dropbox Transfer is probably the sweet spot for a design studio or freelancer. It feels professional to clients, doesn't require them to create an account, handles common creative formats, and gives you password protection, expiration, and download tracking.

For ongoing client projects, rather than one-off deliveries, I'd lean toward Box because its permissions and external-sharing controls are considerably more granular.

For "here's the final 20–100 GB package, please download it", WeTransfer is particularly frictionless and has strong security basics.

Security tip: regardless of service, use a unique password, send the password through a separate channel, set an expiration date, and avoid an unrestricted "anyone with the link" share when the files are confidential.

If you tell me roughly how large your files are (e.g. 5 GB, 50 GB, 200 GB) and whether clients need review/commenting or just downloading, I can narrow it down to the best 1–2 options.

When sending large design files (like layered PSDs, vector packages, or 4K video exports) to external clients, you need a balance of heavy file capacity, professional presentation , and robust security (password protection, download tracking, and expiration dates).

The top services tailored for creative handoffs and secure client delivery depend on your exact workflow:

• Tresorit Send — Best for High-Security / Confidential Work. Built in Switzerland with strict privacy standards, Tresorit offers end-to-end zero-knowledge encryption. You can send massive files, set expiration dates, protect links with passwords, and even revoke access after sending. Perfect if you are dealing with unreleased branding, sensitive intellectual property, or enterprise clients who audit security.
• Hightail — Best for Creative Collaboration & Adobe Integration. Designed specifically for creative professionals, Hightail lets you share enormous files (up to 100GB on higher plans) and includes integrations with Adobe Creative Cloud . Clients can preview high-res files and leave visual, frame-accurate or pixel-specific comments directly in their browser without needing an account.
• Dropbox Transfer — Best if you already use Dropbox. If you store your active projects in Dropbox, you don’t need a new tool. Dropbox Transfer lets you securely send a copy of files up to 100GB straight from your storage without giving clients access to your working folders. It features download confirmations, password protection, and custom expiration dates.
• Smash — Best No-Size-Limit / Ad-Hoc Transfer. If you want a clean alternative to WeTransfer (especially given privacy and terms-of-service shifts on older legacy platforms), Smash has no file size limits —even on its free tier. Paid tiers add custom branding, password protection, and analytics so your client delivery looks professional.
• MASV — Best for Massive Raw/Video Files. If your "large design files" mean multi-terabyte uncompressed video packages, 3D render caches, or massive data drops, MASV is built for raw speed with TPN Gold Shield enterprise security certification. It operates on a pay-as-you-go gigabyte model rather than a monthly subscription.

If you tell me how large your typical file drops are (e.g., under 5GB vs. 50GB+) and whether you need client comment/approval features or just a one-way handoff , I can narrow down the exact service for you.

When sending large design files to external clients, you need a balance of heavy file handling, high-end security (passwords, expiration dates, encryption) , and a polished client experience (no clunky logins required for the client).

The top-tier options tailored specifically for creative workflows and secure large-file delivery include:

1. Tresorit (Best for Maximum Security & Privacy)

• What it is: A Switzerland-based cloud storage and sharing platform built specifically with zero-knowledge, end-to-end encryption.
• Why it’s great for design: Using Tresorit Send , you can securely transfer large files without compromising privacy. Neither Tresorit nor any interceptor can read your files.
• Key security features: Password protection, set expiration dates for download links, disable downloading (view-only), and get delivery tracking notifications.

2. Dropbox Transfer (Best for Seamless, Account-Free Delivery)

• What it is: A dedicated file-delivery feature built into Dropbox ecosystems that lets you send large packages (up to 100 GB on standard plans).
• Why it’s great for design: It doesn’t clutter your core cloud storage space. You drop your massive .zip, .psd , or video folders in, and it generates a gorgeous, branded download page for the client.
• Key security features: Password protection, link expiration dates, and download analytics so you know the exact moment your client reviews the work.

3. Smash (Best for Zero Size Limits & Speed)

• What it is: A dedicated file-transfer tool fromsmash.com designed as a heavy-duty alternative to basic transfer sites.
• Why it’s great for design: There are no file size limits , even on the free tier (files over 2 GB just get priority queueing). It handles gigabytes of raw assets smoothly and previews files natively in the browser.
• Key security features: Optional password protection, link customizability, and encrypted transfers.

4. Frame.io or Hightail (Best for Design Collaboration & Proofing)

• What it is: Specialized creative review platforms designed so clients can interact with high-res files rather than just download them.
• Why it’s great for design: Instead of emailing a static file back and forth, clients can leave time-stamped or pixel-precise visual annotations directly on the design or video in their browser.
• Key security features: Watermarking, granular link permissions, team access controls, and secure password-locked presentations.

If you can tell me how large your typical files are (e.g., 5GB vs 50GB+) and whether you need clients to leave comments/feedback or just download the final files, I can narrow down the ideal service for your workflow.

For sending large design files to external clients (PSD, AI, INDD, CAD, video, renders, etc.), I’d look for four things: large file limits, access controls, client friendliness, and audit/security features. Good options:

My practical picks:

• Solo designer/freelancer: Dropbox Professional is usually the smoothest client experience.
• Small design studio: Box or Dropbox Business.
• Sending final deliverables only: Use a transfer-style link (password + expiration + download tracking) rather than a permanent shared folder. Dropbox Transfer is one example of this workflow.
• Very confidential IP: Tresorit or a business-grade Box setup.

A few security habits matter more than the brand:

• Turn on MFA/2FA for your account.
• Use expiring links instead of “anyone with the link forever.”
• Add a password and send the password separately.
• Disable editing unless the client truly needs it.
• Keep an archive copy separate from the shared folder.

If you tell me the typical file sizes (e.g., 2 GB PSDs vs. 50 GB video/3D packages), number of clients, and whether you need client commenting/approval, I can narrow it down.

When sending large design files (like layered PSDs, vector packages, or 4K video drafts) to external clients, you need a balance of heavy file capacity, professional presentation , and robust security features (like password protection and expiring links).

The best choices tailored for design workflows fall into a few clear categories:

• WeTransfer Pro / WeTransfer Workspace — Best for fast, familiar, and account-free client handoffs. The Pro tier allows transfers up to 200 GB, lets you customize the download page with your branding, and allows you to set custom expiration dates and password protection.
• Tresorit Send — Best for ultimate privacy and confidential client work. It provides zero-knowledge, end-to-end encryption and allows you to send encrypted files up to 100 GB with strict access controls and read/download receipts.
• Dropbox Transfer — Best if you already use Dropbox for storage. It lets you send files up to 100 GB (250 GB with add-ons) via a secure link without eating into your active cloud storage space, plus it includes delivery notifications and password protection.
• Hightail (OpenText) — Best for design-specific feedback. It integrates smoothly with creative tools and allows visual, frame-or-pixel-accurate commenting directly on the platform, preventing messy email feedback chains.
• Filemail — Best for massive, uncompressed multi-gigabyte packages. It handles files of virtually unlimited size with robust encryption, virus scanning, and an interface that feels as simple as sending an email.

If you can tell me:

• How large your typical design files are (e.g., under 10 GB vs. 50 GB+)
• Whether you need client feedback/comments built into the link or just a one-way delivery

I can narrow down the exact service that fits your workflow.

For sending large design files to external clients, I’d shortlist these:

My pick: Box

For PSD/AI/INDD files, large ZIPs, photography, video, and ongoing client projects, I'd lean toward Box. It isn't just a "send this file" service—you can maintain a client folder, control exactly what the client can do, set expiration dates, and revoke access later. Box specifically supports external collaborators and previews PSD and many other file types.

If you want the simplest option: Dropbox

If you're already working in Dropbox, Dropbox Transfer is probably the least-friction choice. Current plans support transfers up to 250 GB, and you can add passwords, expiration dates, download notifications, and branded download pages.

One security tip

For confidential client work, don't just send an unrestricted "anyone with the link" URL. Ideally use recipient-specific access + expiration + download restrictions/password protection, and send the password through a different channel if the files are particularly sensitive.

If you tell me roughly how large your files are (e.g. 5 GB, 50 GB, 200 GB) and whether you need client review/comments or just final delivery, I can narrow this to the best 1–2 choices.
