#️⃣ Hash & UUID Generator
Generate SHA-256, SHA-1, SHA-384, and SHA-512 hashes from text or files, plus create version 4 UUIDs — all computed locally in your browser.
Everything runs in your browser — text and files are never uploaded, and nothing is saved.
Text hashes
SHA-1 is shown for checksums and legacy compatibility only — do not use it for security. MD5 is not offered for the same reason.
File hashes
UUID generator
Version 4 UUIDs from your browser's cryptographic random source. Click any UUID to copy it.
How to Use This Tool
Paste text into the Text hashes box and every algorithm's hash updates instantly — click Copy next to any hash to grab it. Select a file under File hashes to compute its hash without uploading it anywhere, handy for verifying a download matches its published checksum.
In the UUID generator, choose how many you need and click Generate; click any UUID to copy it, or Copy All to grab the whole batch. Hashes and UUIDs are commonly used for verifying file integrity, generating unique database IDs, and de-duplicating records.
