Files are processed 100% locally in your browser. Nothing is uploaded to any server.
What is File Hash Verification?
A file hash (checksum) acts as a digital fingerprint for a file. Even modifying a single bit in the file completely changes the resulting hash. Software developers and distributors publish checksums so you can verify that downloaded files haven't been tampered with or corrupted during transit.
100% Client-Side Privacy
Your files are parsed directly in your browser using the HTML5 FileReader API and native Web Crypto hashing. No file content is ever transmitted over the network or uploaded to our servers.
