About the Binary File Viewer

The same hex dump view, reached by the name people look for when they have a file no application will open.

The first sixteen bytes are usually enough to identify what a file actually is - use the signature detector for a direct answer.

Questions people ask

Is your file uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your file never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
