What this tool does

Minifies or formats JavaScript, sets indentation, uploads local files, and copies/clears content. All processing is local.

Steps

1. Paste or upload JS code.
2. Click Minify to compress, or Format to beautify.
3. Choose indent size via Indent: 4 spaces (adjust as needed).

Examples

• Removes comments and extra whitespace when minifying.
• Keeps block structure and indentation when formatting.

Notes

• Heuristic formatter; may not perfectly handle complex syntax.
• No code is sent to servers; everything runs in‑browser.
