What File Checksum does

Verify a download with its SHA-256 hash. It's one of 133 tools in the Vootkit ecosystem, built to do a single job properly — open it, get your result, move on.

Why use this one

  • Nothing is uploaded. Your file is processed on your own device, so it never travels to a server.
  • No daily limit. Your device does the work, so there's no per-task cost to ration.
  • No watermark. What you get out is what you made.
  • Works on mobile. Same tool, thumb-friendly.

How it works

  1. Open File Checksum — nothing to install.
  2. Add your file or input. It stays on your device.
  3. Adjust the options to suit the result you need.
  4. Download or copy your result.

Example

Stripping location data out of a photo before posting it publicly.

Questions

Is File Checksum free?

Yes. File Checksum is free to use on Vootkit, with no account, no watermark and no daily task limit.

Are my files uploaded?

No. File Checksum runs entirely in your browser — your file is processed on your own device and never sent to a server. There is nothing for us to store or delete.

Do I need to install anything?

No. File Checksum works in any modern browser on desktop, tablet or phone. Open the page and start.

Is there a limit on how many times I can use it?

No. Because the work happens on your device rather than our servers, there is no per-task cost and therefore no daily cap.
