Decode, diff and format data — without pasting it into some random site
JSON, JWT, Base64, URLs, hashes, diffs and color tools process in your browser. Use and preview without signup; if you request a file download while signed out, only the finished export is preserved temporarily through sign-in.
Format & Decode
JSON, HTML, Base64, URL, JWT, hash and diff tools.

Cryptic Base64 in logs and payloads slows you down. Decode to readable text or encode any text or file — URL-safe, UTF-8 safe, and instant in your browser.
