WeTransfer alternative
Share your files without anyone being able to read them.
Short answer
Filarr Send is a French alternative to WeTransfer: your files are end-to-end encrypted in your browser (AES-256-GCM) before upload, and the key stays in the link’s fragment (#), never sent to the server. Free with no account, up to 4 GB in total; the recipient installs nothing.
Checked
The WeTransfer alternative for sensitive data: end-to-end encryption, no account for the recipient, and a host that cannot read your files — guaranteed by cryptography, not by a promise.
Convenient doesn’t mean compliant
WeTransfer is fast, and your files are indeed encrypted in transit and at rest — but WeTransfer holds the keys, at non-EU sub-processors, on a service whose terms recently drew fire. For a contract, a payslip, an ID or a patient record, that’s not a detail: it’s personal data you hand to a third party that can read it. Filarr keeps the simplicity of a link — but encrypts before it leaves, with a key we never hold.
WeTransfer vs Filarr
| Capability | WeTransfer | Filarr |
|---|---|---|
| End-to-end encryption | Not advertised — encrypted in transit and at rest, keys on the service side | Yes — the key never leaves your browser |
| Hosting | US sub-processors | Cloudflare R2, Western Europe region — encrypted before upload, unreadable by the host |
| AI training on your files | 2025 terms controversy, later walked back | Impossible — we only ever see ciphertext |
| Account required to deposit | No, but no structured collection | No — plus per-depositor tracking, reminders, checklist |
| DPA (GDPR Article 28) | Depends on the plan | Available and signable |
| Revoking a link | Depends on the plan | Any time — the encrypted file is deleted |

How it works
1. Drop your file
It’s encrypted in your browser before a single byte leaves. The key stays with you.
2. Share the link
By email, message, QR. The decryption key travels in the fragment (#) — never sent to our servers.
3. The recipient downloads
The file decrypts in their browser, no account. You can revoke the link at any time.
Need to receive files instead of sending them? The file request does the reverse: a link others deposit into, decryptable only by you.
Frequently asked questions
Why is WeTransfer a GDPR concern?+
WeTransfer encrypts in transit (TLS) and at rest (AES-256) — but it holds the keys: your files stay readable on its side. The 2025 controversy over terms allowing AI training was a reminder of that, and its sub-processors are in the US (a Schrems II transfer question). For sensitive data — IDs, HR files, health documents, accounting records — the problem is not the transport, it is who can read.
How is Filarr different?+
Each file is encrypted in your browser (AES-256-GCM) before anything is sent. The key travels in the URL fragment (#), the part of a link browsers never send to the server. Our servers only ever store opaque ciphertext: we cannot read, scan or hand over your files, even on legal demand. That’s end-to-end encryption, not a hosting promise.
Does my recipient need an account?+
No. To send, you get a link; to receive, you create a deposit request and the depositor opens the link and drops their files — no account, no install, from their phone if needed.
How large can files be?+
Up to 4 GB in total with no account, encrypted and uploaded in chunks (no RAM limit). An account raises that ceiling with the plan: 20 GB on Solo, 50 GB on Pro, up to 200 GB on Enterprise.
Is it really free?+
Encrypted sending and file requests are free, no account. A free account adds the dashboard (account-bound keys, cross-device management). Filarr for Teams — your-brand pages, batch sending, audit log, per-recipient tracking — is paid. See pricing.
