⌨️ Developer Tools
Everyday developer utilities: format and validate JSON, encode and decode Base64 and URLs, and generate SHA-256, SHA-1 or MD5 hashes. Everything runs locally — your data never touches a server.
JSON Formatter
Paste JSON and this tool tells you instantly whether it is valid — and if not, exactly where it breaks, with the error position.
Base64 Encoder / Decoder
Base64 represents binary data using 64 safe ASCII characters, which is how emails attach files, JSON carries binary blobs and…
URL Encoder / Decoder
URLs may only contain a limited set of ASCII characters, so spaces, accents and symbols are written as %XX percent-escapes.
Hash Generator
A hash function turns any input into a fixed-length fingerprint that is easy to compute and practically impossible to reverse.
