Hash generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes of text or files free in your browser. 100% private, no upload, ideal for checksums. No sign-up.
100% private — files never leave your deviceHow to use
- Choose algorithms. Tick the hashes you want — MD5, SHA-1, SHA-256 and/or SHA-512.
- Enter text or a file. Type or paste text for a live hash, or upload a file to hash its bytes.
- Read the digests. Each selected algorithm's hash appears instantly, in lower or upper case.
- Copy what you need. Copy a digest to compare against a published checksum.
Features
- Four algorithms. Compute MD5, SHA-1, SHA-256 and SHA-512 digests in one place.
- Text or file. Hash typed text live, or drop in a file to verify its checksum.
- Nothing leaves your device. Hashing runs locally via WebAssembly, so private files are never uploaded.
- Upper or lower case. Switch the output case to match the checksum you're comparing against.
- Fast and live. Text digests update as you type; file hashing is quick even for larger files.
When to use it
- Verify a downloaded file against its published SHA-256 checksum.
- Generate an MD5 or SHA-1 fingerprint of a file or string.
- Create a hash of text for a cache key or integrity check.
- Compare two files by their digests to confirm they're identical.
- Produce a checksum to share alongside a file you distribute.
Is it private?
Hashing runs locally in your browser with WebAssembly and your data is never uploaded.
Frequently asked questions
Is this hash generator free?
Yes, it's completely free with no sign-up and no limits.
Are my text or files uploaded?
No. Hashing runs locally in your browser using WebAssembly, so nothing is ever uploaded.
Which algorithms are supported?
MD5, SHA-1, SHA-256 and SHA-512. You can compute any combination at once.
Can I hash a file?
Yes. Upload a file and its contents are hashed on your device to produce a checksum.
Should I use MD5 for security?
MD5 and SHA-1 are fine for checksums but are not collision-resistant; use SHA-256 or SHA-512 for security-sensitive purposes.
Do I need to install anything?
No. It runs entirely in your web browser with nothing to install.
