🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
This tool computes MD5, SHA-1, and SHA-256 hashes for two texts or files side by side and tells you whether they match. It's handy for developers and security-conscious users who need to verify a downloaded file hasn't been corrupted, or check whether two pieces of text are byte-for-byte identical. Everything runs locally in your browser, so nothing is ever uploaded to a server.
How to use
- Choose 'Compare Text' or 'Compare Files' from the tabs at the top.
- Paste text or drop a file into the Target A panel on the left.
- Paste or drop the second text or file into Target B on the right.
- Review the auto-computed MD5/SHA-1/SHA-256 values and the MATCH/MISMATCH result shown below.
FAQ
- What does it mean if the hashes match?
- It means the two inputs are byte-for-byte identical. Even a single-bit difference produces a completely different hash, making tampering or corruption easy to spot.
- Which hash should I trust — MD5, SHA-1, or SHA-256?
- For simple integrity checks any of them works, but for anything security-sensitive prefer SHA-256, since MD5 and SHA-1 are considered weak against deliberate collisions.
- Can I compare large files?
- Yes. Files are read and hashed directly in your browser's memory without any upload, though very large files may take longer depending on your device's performance.
