SHA-256, SHA-1, MD5 & SHA-512 checksum calculator

Hash text or drag-drop files, see every algorithm at once, and verify a checksum with an instant MATCH / NO-MATCH — right here in your browser.

Every feature. No limits. No sign-up. No watermark. Nothing uploaded. Free forever. Hashing runs 100% in your browser — text and files are read into memory and digested locally using the browser's native crypto engine (plus an in-browser MD5 implementation), and never touch a server. Unlike tools that cap file size or hide algorithms behind a paywall, this one gates nothing.
Nothing is ever uploaded. Even large files are hashed entirely on your device — there is no network request, so there is nothing to leak.
