File checksum
Generate a file fingerprint to compare a download with its published SHA-256 or SHA-512 checksum. Even a small byte change produces a different fingerprint. Select the same hash algorithm used by the trusted reference value.
How to use this tool
- Choose your source file, drag it into the upload area, or import a direct public file URL.
- Review the settings and create your result.
- Download and check the output before using it.

Output and limitations
Calculate a SHA-256 or SHA-512 fingerprint for a file on your device.
Compare the downloaded hash with a trusted published checksum. A matching hash verifies identical bytes; it does not prove a file is safe.
Where are my files processed?
Selected files are processed in your browser. Importing a URL uses the download service to retrieve the remote file.
What if processing fails?
Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
