Receive a file

Someone’s sending you a file.

Open the private Blixt invitation they shared with you. The file is encrypted in transit. You can compare the six-digit security code; the transfer waits when enforced verification is enabled or one peer uses Android.

Use the invitation exactly as the sender gave it to you. A direct transfer invitation starts with https://blixt.pro/r#. Everything after # stays out of web requests and server logs. This page deliberately ignores ?code= and all other query parameters.

  1. Open the private invitation link. If Blixt is installed, choose “Open the transfer” to hand it to the app. Do not rewrite the invitation as a query-string link.
  2. Install Blixt if you need it. Download the current builds: Windows 0.27.0 ships as Installer or portable zip, with update checks built in. Android Preview 0.27.0: Sideloaded release APK; Android 10+, arm64. iOS is planned but not available yet.
  3. Compare the 6 digits when verification is required. Android requires the human check by default; desktop waits only when either peer enables enforced verification. Matching digits let you verify that nobody sits between you.

Got a blixt.pro/storage share link instead of a code? Just open it in your browser — no install needed at all.

Fair questions

Before you open a stranger’s invitation.

Is this safe?

The transfer is encrypted with TLS 1.3, and the certificate fingerprint is pinned before a single byte moves. The 6-digit code is derived from the encrypted session itself: if anyone — including our own server — sat in the middle, your two screens would show different digits. That’s why you compare them out loud, over a channel the network can’t fake. Every chunk is also BLAKE3-verified, so what arrives is exactly what was sent. The full model is at /security.

Is it free?

Yes — the free plan is $0 and receiving needs no card. Paid plans add bigger transfers and more; see pricing.

Can I do this on my phone?

Android Preview 0.27.0 is available. Sideloaded release APK; Android 10+, arm64. It is for testing, not sensitive production transfers. iOS is planned. A bCloud share link already opens in any mobile browser; see mobile options.
