Hash Anything — Without Uploading It

Paste text or drop a file and get MD5, SHA-1, SHA-256, SHA-384, and SHA-512 at once — with a verify field for checksums, hashed locally via WebCrypto. Nothing leaves your browser.

Hash Generator

Built for developers verifying checksums, deduplicating content, or hashing secrets. Five digests in one pass, computed on your device. Fully client-side — no network calls, no storage, files are read locally only.

MD5 and SHA-1 are legacy digests — collision-prone, fine for checksums and dedup, not for security; use SHA-256 or better for anything security-critical.

How to use:

  1. Pick Text (hashes live as you type) or File (pick a file — it is read locally in chunks, never uploaded)
  2. All five digests — MD5, SHA-1, SHA-256, SHA-384, SHA-512 — compute at once; toggle UPPERCASE if your checksum source uses capital letters
  3. Paste an expected hash into the verify field to get an instant MATCH / NO MATCH verdict (comparison is case-insensitive)
  4. Copy any single digest with its copy button
  5. Heads-up on MD5/SHA-1: great for checksums and dedup, but not collision-resistant — don't use them for passwords or signatures

Everything runs in your browser: no network calls, no analytics on your input, nothing stored. SHA digests use the browser's built-in WebCrypto; MD5 is computed by a small local implementation since WebCrypto dropped it.
