How do I send secure files online with no registration and self-deleting storage?

Bypass heavy security portals or unencrypted email attachments. bridg.fun secures your file transfer directly in your browser client using Web Crypto standards.

  1. 1

    Open bridg.fun and drop your file

    Open bridg.fun in any browser — no account, no install needed. Drag and drop your PDF, contract, spreadsheet, or zip archive directly onto the Send zone. The file is encrypted right in your browser before it goes anywhere.

  2. 2

    Set self-destruct timer & get PIN

    Choose how long the file stays alive — 15 minutes, 30 minutes, or 1 hour — or enable "delete after first download" for true one-time access. Your file is AES-256 encrypted client-side and a 6-digit session PIN is issued instantly.

  3. 3

    Recipient downloads, file self-destructs

    Send the PIN to your recipient. They enter it on bridg.fun, the file decrypts locally in their browser, and downloads directly. The moment the timer expires or they download it, the encrypted blob is permanently wiped from our servers — no trace left.

Frequently Asked Questions

What is Client-Side Web Cryptography?

It means the mathematical encryption of your files happens inside your local browser tab (Safari, Chrome, Firefox) before the bits are sent to the cloud. The password/PIN is generated locally and is not shared with the server, making it mathematically impossible for bridg.fun to decrypt or read your files.

Can a file be recovered once deleted?

No. bridg.fun is designed for ephemerality. Once a file self-destructs (either after downloading or when its 15m/1h timer expires), it is permanently wiped from our server memory. We do not retain backup logs or shadow copies of files.

Are there any limits on file extensions?

No. You can secure any file type: PDFs, financial spreadsheets (.xlsx), zip files, text documents (.docx), or presentations. The only constraint is keeping the file size under 50MB.
