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 0.18.0 ships as Installer or portable zip, with update checks built in. Android Preview 0.1.0: Sideloaded debug 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 0.1.0 is available. Sideloaded debug 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.
