FAQ

Frequently Asked Questions

No, this is a formatter, not a linter. It fixes the visual structure (indentation, spacing) but assumes your code is syntactically valid.
No. The formatting process is stateless. Your code is processed and returned immediately; we do not store or log your input.
This tool is made for formatting using Prettier-compatible rules. For decompressing minified code, use our Code Compressor tool in reverse (Decompress) mode.
Yes. Taking minified, production-compressed code and making it readable again is one of the most common use cases for a code formatter. Paste minified JavaScript, CSS, or HTML and the formatter will reconstruct the indented, multi-line structure. For code that has been deliberately compressed using a minifier, the Code Compressor tool handles the reverse direction: going back to minified output when you are ready to deploy. For removing comments from formatted code, the Code Comment Remover strips all comment syntax cleanly.
The code formatting is handled entirely in the browser using client-side JavaScript formatting libraries. Your code is never sent to an external server, never stored, and never logged. After formatting, if you need an AI-powered explanation of what the code does, the AI Code Explainer gives you a plain-English breakdown of any snippet.
