Format and validate data
Pretty-print JSON, validate it and track down syntax errors instantly. Minify HTML, CSS, JavaScript and SQL before shipping, and convert between JSON, CSV, YAML and TypeScript interfaces without leaving the page.
Encode, decode and secure
Encode and decode Base64, URLs and HTML entities, decode JWTs to inspect claims, generate MD5, SHA-256 and bcrypt hashes, and create strong random passwords and UUIDs.
Work faster in the browser
The best developer tool is the one already open in a tab. Bookmark this page and reach for it during code reviews, debugging sessions and API work instead of reaching for a command line.
