Send big files. They vanish after one download.
Encrypted in your browser, password-protected, and gone after one download — no account needed. Drop your files to start.
Send and receive, end to end
Encrypt in the browser, share a link, and watch it self-destruct on download — exactly what your recipient sees.
Animated demo · actual speed depends on your connection
Built private, not bolted-on private
Most transfer tools can read your files. DocuChan is architecturally unable to — and that changes everything.
True end-to-end encryption
Your file is encrypted in your browser with a key that lives in the link's # fragment — which is never sent to our servers. We store ciphertext we literally cannot open.
Burn after download
Choose self-destruct and the file is hard-deleted the instant it's downloaded — no lingering copies sitting on a server after the handoff is done.
A genuinely generous free tier
5 GB per file, password protection, custom expiry — free, while WeTransfer dropped its free plan to 3 GB per month.
Password protection
Add a password and even someone with the link can't open the file without it. The password never reaches our servers in the clear.
No ads. No tracking.
We don't profile you, sell data, or wrap your transfer in advertising. The product is the product — not your attention.
Fast, resumable uploads
Encryption runs in parallel with the upload and streams straight to storage. Big files go up quickly, and interrupted uploads can resume.
Three steps, thirty seconds
No account, no app, no learning curve.
Drop your files
Pick a file — or several, and we bundle them into one encrypted download. Add a password if you like, and choose how it expires: on download or after a set time.
We encrypt & upload
Your browser encrypts the file and uploads the ciphertext directly to storage. The key stays with you.
Share the link
Copy the link or scan the QR code. When the recipient opens it, the file decrypts in their browser — then self-destructs.
DocuChan vs WeTransfer
WeTransfer keeps shrinking its free plan. Here's how the two line up today.
| Feature | DocuChan | WeTransfer (free) |
|---|---|---|
| Free file size | 5 GB per file | 3 GB / month total |
| End-to-end encrypted | Yes — key never leaves you | No |
| Burn after download | Yes | No |
| Ads & tracking | None | Ads on free plan |
| Password protection (free) | Yes | Paid only |
If you can't read it, no one can
DocuChan is open about exactly how it protects your files: encryption happens in your browser, the decryption key travels only inside the link fragment (which browsers never send to servers), and expired or burned files are permanently deleted by an automated sweeper. A breach of our servers would expose nothing but unreadable ciphertext.
Questions, answered
Is it really free?
Yes. You can send files up to 5 GB with password protection and self-destruct, no account and no payment. Paid plans exist for bigger files, longer link lifetimes, and team features — but the free tier is meant to stay genuinely useful.
Can DocuChan see my files?
No. Files are encrypted in your browser before upload, and the key lives in the part of the link (the # fragment) that browsers never transmit to a server. We only ever hold ciphertext we can't decrypt.
Can I send several files at once?
Yes. Select or drop multiple files and DocuChan bundles them into a single encrypted download — your recipient gets one link, and the files arrive together as one package.
What does "self-destruct" mean exactly?
You can set a file to delete the moment it's downloaded (burn-after-download) or after a time you choose. Once deleted, it's gone from storage — the link stops working.
Do I need to install anything?
No. DocuChan runs entirely in the browser on any device. Share a link or a QR code and the recipient just clicks.
