Hash Comparison Tool
Instantly compare the MD5, SHA-1, and SHA-256 of two texts or files
Drop in two pieces of text or two files and this tool computes their MD5, SHA-1, and SHA-256 hashes, shows them side by side, and tells you whether they match. It's handy for developers and security engineers who need to verify the integrity of a downloaded file or confirm that a piece of text hasn't changed by even one character. Your text and files are processed entirely in the browser and never uploaded.

How to use
- Choose 'Compare Text' or 'Compare Files' from the tabs at the top.
- Paste text or drag a file into the left side (Item A).
- Add the text or file you want to compare against on the right side (Item B).
- Check the MD5, SHA-1, and SHA-256 values computed automatically, along with the MATCH or MISMATCH verdict below.
FAQ
- What does it mean when the hashes match?
- It means both inputs are byte-for-byte identical. Change even a single byte and the hash changes completely, which makes corruption or tampering easy to spot.
- Should I look at MD5, SHA-1, or SHA-256?
- Any of the three works for a routine file integrity check, but for anything security-sensitive rely on SHA-256, since MD5 and SHA-1 are vulnerable to collision attacks.
- Can it handle large files?
- Yes. Files are read straight from browser memory and hashed locally, so nothing gets uploaded. Very large files may just take longer depending on your device's speed.
