Conservative output
This utility is for simple scripts, not a replacement for a full bundler or tree shaker.
Keep source readable
Store readable JavaScript somewhere before replacing public assets with minified code.
How to use JS Minifier
Compact small JavaScript snippets after behavior has already been tested in the page.
Paste JavaScript
Use a small script or snippet that has already been tested.
Minify JS
StaticX returns compact JavaScript suitable for review and preview.
Test behavior
Preview the page and confirm forms, buttons, and analytics still behave correctly.
JavaScript minification is safest after behavior is already correct.
Whitespace is rarely the reason a script fails, but minifying an untested script can hide problems and make debugging harder.
Use project build tools for application bundles. Use this utility for smaller static-site scripts that need a quick cleanup.
JavaScript minification notes
Not a bundler
It does not resolve imports, transpile TypeScript, or remove unused packages.
Avoid secrets
Public JavaScript is visible to visitors. Never include private tokens or keys.
Preview interactions
Always test the page after replacing JavaScript.
Questions about JS Minifier
Short, practical answers for using this page safely.
Can I minify a full React bundle?
Use the React or Vite build process instead. This tool is intended for small scripts and snippets.
Does minification hide source code?
No. Public JavaScript remains downloadable by visitors even when minified.
Can this fix JavaScript errors?
No. Fix errors before minifying.
