Hash Generator
Compute SHA-256, SHA-1, and MD5 hashes from text or files in your browser. Free online hash generator — no upload.
Compute checksums without uploading files
Hash strings or files locally to verify downloads, compare artifacts, or debug cache keys — sensitive binaries stay on your machine.
What you can do with it
- Verify a download
- Compare a published SHA-256 against a file you received without sending the file to a hash site.
- Debug cache or ETag logic
- Quickly digest sample payloads when building CDN or storage integrations.
How to generate a hash
- Paste text or choose a file to hash.
- Pick SHA-256, SHA-1, or MD5.
- Copy the hex digest from the output.
Checksum files without uploading binaries
Vendor SHA-256 lists exist so you can verify downloads. Hashing locally means installers, backups, and proprietary builds never pass through someone else’s hash calculator.
SHA-256 vs legacy digests
Prefer SHA-256 for integrity checks. MD5 and SHA-1 remain for legacy compatibility — do not use them for new security decisions.
