Browser-side processing
Pasted code and loaded files are processed with local JavaScript. Normal workbench actions do not send source code to the application server.
about the project
Developer utilities that keep source code in the browser.
Free Code Cleaner combines common formatting, cleaning, validation, conversion, extraction, regex, and text tools in a single accessible interface.
Built for privacy, speed, and practical everyday work.
Parallel where it helps
Independent transformations can run in a bounded Web Worker pool. The worker count is limited to avoid wasting memory or slowing lower-powered devices.
No account required
The toolbox is available without registration. Draft text, theme choice, and editor layout are stored locally in the browser when those features are used.
design goals
A focused alternative to separate single-purpose converter sites.
The application groups actions by the selected or detected language so irrelevant controls stay out of the way. It supports keyboard navigation, visible focus, responsive layouts, light and dark themes, local autosave, file loading, downloadable output, and offline caching.
Stripe is contacted only when a visitor intentionally starts a contribution checkout. Advertising code is loaded only when an AdSense publisher ID is configured by the site operator.
