About

Toolaxo is a collection of free online tools built for developers, designers, and anyone who regularly works with code or data. Formatters, converters, encoders, generators — the things you reach for constantly but rarely want to install a dependency for or write a one-off script to handle.

The tools cover a wide range: JSON formatting and validation, SQL and XML beautifiers, Base64 and URL encoding, string case conversion, UUID generation, image-to-Base64 conversion, and more. New tools get added regularly based on what's actually useful in day-to-day development work.

None of the tools send your data anywhere. There is no server processing your input — formatting, converting, and encoding all happen locally in your browser using JavaScript. This matters when you're working with sensitive data: API keys, database queries, internal config files, or anything else you'd rather not paste into a form that ships it to a third-party server.

The tools also work offline once the page is loaded. If your internet connection drops while you're in the middle of formatting a large XML file, nothing breaks.

There's no sign-up, no login, and no paywall. Open the tool, use it, and leave. The editor remembers your last input across page reloads so you don't lose work if you close the tab accidentally, but that data stays in your browser's local storage and never leaves your machine.

The goal is to be the tool you reach for without thinking — fast to load, no ads in the way, no prompts to create an account before you can format a JSON string.
