SHA hashes
SHA-1 is included for legacy integrity checks only — it is not collision-resistant, so use SHA-256 for security. MD5 is not supported by browser Web Crypto and is not recommended.

Why compare files in the browser?
Developers and testers often can't upload company or client files to a random website. This tool runs entirely in your browser using built-in APIs — the files are read into memory locally, compared, and hashed without ever being sent anywhere. You can even use it offline.
Text compare vs binary compare
Text compare works line by line, so you see added, removed, and changed lines (with options to ignore whitespace, case, blank lines, and line endings). Binary compare works byte by byte and reports the first differing offset (in decimal and hex) and the differing byte values — ideal for images, archives, and other non-text formats.
What is a file hash?
A hash is a fixed-length fingerprint computed from a file's bytes. If two files produce the same SHA-256 hash, they are virtually certain to be identical; if a single byte changes, the hash changes completely. Hashes are how you verify a download wasn't corrupted or tampered with.
SHA-256 vs MD5
MD5 and SHA-1 are older and no longer collision-resistant — an attacker can craft two different files with the same digest, so they shouldn't be trusted for security. SHA-256 (and SHA-384/512) are the modern choice for integrity and security. Browser Web Crypto doesn't offer MD5 at all, which is why this tool doesn't include it.
Your files never leave your device
Nothing is uploaded, stored, logged, or tracked. There is no account, no watermark, and no server in the middle — the comparison and hashing happen on your machine.
