Encrypted file transfer
The Firefox Send alternative
Firefox Send was the simple, private way to share a file with an encrypted link — until Mozilla shut it down in 2020. BIShare brings that back: files are end-to-end encrypted in your browser, shared with a link that auto-expires, and never tied to an account. It also does something Firefox Send never could — send device to device instantly when you're on the same network.
What happened to Firefox Send?
Mozilla discontinued Firefox Send in September 2020 after it was abused for malware, and never brought it back. That left a gap: a dead-simple, end-to-end encrypted, no-account way to send a file with a link. BIShare fills it — the encryption key lives in the link fragment and never reaches our servers, so we only ever store ciphertext, exactly the model Firefox Send used.
How BIShare keeps it private
Encrypted in your browser
Turn on end-to-end encryption and the file is encrypted before it leaves your device. The key travels in the link's #fragment, which browsers never send to a server — so we store ciphertext we can't read.
A link that self-destructs
Share a link, QR code, or 6-character code. The recipient opens it in any browser and downloads — no account, no install. Links auto-expire after 24 hours instead of lingering in the cloud.
Or skip the cloud entirely
On the same Wi-Fi, BIShare sends the file straight between devices, end-to-end encrypted, with no upload at all — something Firefox Send never offered.

Firefox Send alternative: FAQ
What is the best Firefox Send alternative?
BIShare. It matches the thing people loved about Firefox Send — end-to-end encrypted file sharing through a simple, account-free link that expires — and adds instant nearby device-to-device transfer on top.
Is Firefox Send coming back?
No. Mozilla permanently discontinued Firefox Send in 2020 and has said it won't return. If you're looking for the same encrypted-link experience, BIShare is the closest replacement.
Is BIShare really end-to-end encrypted like Firefox Send?
Yes. The file is encrypted in your browser with a key that rides in the link fragment and never reaches our servers, so we only store ciphertext. Nearby transfers are encrypted device-to-device and never touch the cloud at all.
Do I need an account?
No. You can send and receive without signing up. You just share a link, QR code, or 6-character code, and the recipient opens it in any browser.
How large a file can I send?
Encrypted share links carry files up to 100 GB free. For nearby device-to-device transfers over your own Wi-Fi there's no size cap, because nothing is uploaded to a server.
