What is File Hash Checker?
A file checksum calculator generates cryptographic hash values (MD5, SHA-1, SHA-256) for any file. Use it to verify file integrity after downloads, detect tampering, or compare two files. Everything runs locally — your files never leave your device.
How to use
- Drop a file or click to select one from your device.
- View the computed MD5, SHA-1, and SHA-256 checksums instantly.
- Paste a known checksum to verify it matches, or copy any hash to share.
Result
After downloading a Linux ISO, paste the SHA-256 from the website into the verify field. A green check confirms the file wasn't corrupted during download.
