7 Best WeTransfer Alternatives in 2026 (More Secure & Free)

7 Best WeTransfer Alternatives in 2026 (More Secure & Free)

WeTransfer remains one of the most recognizable file-sharing services around, but it is starting to show its age in 2026. Capped file sizes, no end-to-end encryption, and data stored on infrastructure subject to US jurisdiction are just a few reasons to look for a WeTransfer alternative. Whether you are a freelancer, a small business owner, or simply someone who cares about where your data ends up, this comparison will help you make an informed choice.

Why Look for a WeTransfer Alternative?

Before diving into the comparison, here are the main limitations of WeTransfer worth knowing about:

• Limited encryption: WeTransfer encrypts files in transit (TLS) and at rest, but does not offer end-to-end encryption. This means WeTransfer can technically access your files on their servers.
• 3 GB on the free plan: a limit that creative professionals hit almost immediately, with a cap of 10 transfers per month.
• Data retention: files remain on their servers for only 3 days (down from 7 previously) with no granular control over deletion.
• GDPR compliance concerns: the hosting infrastructure falls under the US Cloud Act, raising questions about EU data sovereignty.

Comparing the 7 Best Alternatives

1. ZeroTrustTransfer: Zero-Knowledge Encryption, Made in France

ZeroTrustTransfer is the only service in this comparison that combines zero-knowledge encryption with hosting entirely in France. In practical terms, this means that even the ZeroTrustTransfer team cannot access your files: encryption and decryption happen entirely in your browser.

• Max size: 5 GB free, up to 20 GB on the pro plan
• Encryption: AES-256, zero-knowledge, decryption key never sent to the server
• Strengths: native GDPR compliance, no sign-up required for free transfers, clean interface
• Weaknesses: less brand recognition than the big names, no native mobile app yet

Try ZeroTrustTransfer for free and see for yourself.

Bonus: for sharing sensitive documents (IDs, contracts, official paperwork), check out ZeroTrust ID. This companion app adds a custom watermark to your documents and gives you full control over who can access them — ideal for sharing a passport or bank details securely.

2. Tresorit Send: The Swiss Encryption Standard

Tresorit is a Swiss company with a strong reputation for security. Tresorit Send lets you send end-to-end encrypted files without the recipient needing an account.

• Max size: 5 GB
• Encryption: E2E with AES-256
• Strengths: established reputation, integrates with the wider Tresorit ecosystem, GDPR and HIPAA compliant
• Weaknesses: pricing is steep for individuals, interface can feel spartan

3. Proton Drive: File Sharing From the ProtonMail Team

The team behind ProtonMail offers Proton Drive, an end-to-end encrypted cloud storage service with built-in file sharing via link.

• Max size: 5 GB free (total storage, not per file)
• Encryption: E2E
• Strengths: full Proton ecosystem (mail, VPN, calendar), open source
• Weaknesses: storage shared across Proton services, not optimized for one-off large file transfers

4. Send Anywhere: Speed First

Send Anywhere focuses on simplicity with a 6-digit code system for file retrieval. Transfers go directly between devices when possible.

• Max size: 10 GB
• Encryption: TLS in transit only
• Strengths: cross-platform (iOS, Android, Windows, Mac, Linux), fast peer-to-peer transfers
• Weaknesses: no E2E encryption, data routed through South Korean servers, ads on the free tier

5. Smash: The French Option With No Size Limits

Smash stands out by having no strict file size limit, though free transfers over 2 GB are placed in a waiting queue with reduced priority.

• Max size: 2 GB priority (larger files queued), unlimited on Pro
• Encryption: TLS in transit
• Strengths: no strict size cap, polished interface, customizable download pages
• Weaknesses: no end-to-end encryption, free transfers over 2 GB are queued, files kept only 7 days on the free tier

6. Swiss Transfer: Swiss Generosity

Built by Infomaniak, Swiss Transfer offers up to 50 GB per transfer, completely free.

• Max size: 50 GB
• Encryption: TLS + encryption at rest
• Strengths: extremely generous limit, Swiss hosting, no account required
• Weaknesses: no E2E encryption, no pro tier with advanced features

7. Send: The Open-Source Successor to Firefox Send

After Firefox Send was discontinued in 2020, the community picked up the project. Send (timvisee/send) is a self-hostable, open-source file transfer tool with end-to-end encryption.

• Max size: 2.5 GB (varies by instance)
• Encryption: E2E in the browser
• Strengths: open source, self-hostable, completely free
• Weaknesses: you need to find a reliable instance or host your own, no official support

How to Choose the Right Alternative

The best choice depends on what matters most to you:

• Maximum security: ZeroTrustTransfer or Tresorit Send — the only services offering true zero-knowledge or full E2E encryption.
• Large free transfers: Swiss Transfer (50 GB) or Smash (no strict size limit).
• Full ecosystem: Proton Drive if you already use ProtonMail.
• Total control: self-host Send for complete ownership.
• GDPR compliance + EU data sovereignty: ZeroTrustTransfer is the only option that checks every box.

FAQ

What is the best free alternative to WeTransfer?

For sheer volume, Swiss Transfer is hard to beat with its 50 GB free limit. If security is your priority, ZeroTrustTransfer offers 5 GB free with zero-knowledge encryption — something WeTransfer does not provide at any price tier. It comes down to what matters more: file size or confidentiality.

Is WeTransfer actually secure?

WeTransfer encrypts transfers in transit (TLS) and files at rest, but it does not offer end-to-end encryption. This means WeTransfer technically has access to your files on their servers. For sensitive documents (contracts, personal data, intellectual property), a service with E2E encryption is strongly recommended.

Can I send files larger than 2 GB for free?

Yes, several alternatives make this easy. Swiss Transfer allows up to 50 GB, Smash accepts files over 2 GB but places them in a queue, Send Anywhere goes up to 10 GB, and ZeroTrustTransfer supports 5 GB. All of these are free and do not require an account.
