Hash Generator
Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text or file. Everything is calculated locally, so your data never leaves your browser.
To generate a hash, choose Text or File, provide your input, and MD5, SHA-1 and SHA-256 hashes are computed instantly in your browser — nothing is uploaded.

How to use Hash Generator
- 1Choose Text or File input.
- 2Type or paste your text, or drop in a file.
- 3The MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes compute instantly.
- 4Copy any hash with one click.
How it works
Type or paste text, or drop in a file, and hashes are computed instantly using the browser's native Web Crypto API (with a built-in MD5 for legacy checksums). Copy any hash with one click.
Because it runs locally, you can hash sensitive data and large files without uploading them.
Common uses
Verifying a downloaded file against a published checksum, generating a fingerprint for cache-busting, or comparing two files by their hashes.
Frequently Asked Questions
Which hash algorithms are supported?
MD5, SHA-1, SHA-256, SHA-384 and SHA-512. SHA-256 is the usual choice for file integrity; MD5 and SHA-1 are provided for legacy checksums.
Are my files uploaded to check the hash?
No. Hashing runs entirely in your browser using the Web Crypto API, so files and text never leave your device.
Should I use MD5 for security?
No — MD5 and SHA-1 are considered broken for security purposes. Use SHA-256 or stronger when integrity matters.
