What is AnsaTools?

AnsaTools is a comprehensive suite of free, privacy-first developer tools built by AnsaSolutions. Every tool runs entirely in your browser — your data is never sent to any server, ensuring complete privacy and security for sensitive information like API keys, SQL queries, and authentication tokens.

Our growing collection of 42+ tools covers essential developer workflows including JSON formatting and validation, Base64 encoding and decoding, SQL query formatting with dialect-aware capitalization, URL encoding and decoding with automatic query parameter parsing, regular expression testing with live highlighting, and cryptographic hash generation. We also offer color conversion between HEX, RGB, and HSL formats with WCAG contrast checking, JWT token decoding and encoding, QR code generation, password generation, and many more utilities.

Whether you are debugging a REST API response, formatting a complex SQL query for a code review, validating a regular expression, or generating a secure password, AnsaTools provides the right tool — instantly, privately, and with zero setup. All tools work offline as a Progressive Web App (PWA), so you can install AnsaTools and use it even without an internet connection.
