JSON Formatter & Validator
Format, validate, beautify, and minify JSON data with exact syntax error line and column detection.
Base64 Encoder & Decoder
Encode text to Base64 and decode Base64 strings back to UTF-8 text with URL-safe support.
URL Encoder & Decoder
Encode and decode URLs and query parameters using standard percent-encoding.
UUID Generator
Generate cryptographically secure RFC 4122 Version 4 UUIDs individually or in bulk.
Unix Timestamp Converter
Convert Unix epoch timestamps (seconds & milliseconds) to human-readable dates and vice-versa.
Hash Generator
Generate cryptographic hashes (SHA-256, SHA-384, SHA-512, SHA-1, and MD5) entirely in your browser.
Private, Browser-Side Developer Utilities
Engineers often need to format JSON payloads, decode Base64 strings, or generate UUIDs, but pasting sensitive API responses or credentials into unknown online tools is a serious security risk. Chartixo processes all developer operations locally with Web Crypto and native APIs, guaranteeing your data stays safe.
