What would you like to do next?
Minify JavaScript snippets
For small demos and inline scripts, a quick minifier can make JavaScript more compact. Paste a snippet and this tool removes comments and obvious extra whitespace so the output is easier to embed or share.
Use a real bundler for production apps
This is a lightweight snippet helper, not a full JavaScript parser. Large or modern codebases should use a build tool that understands the language completely.
Frequently asked questions
Is this safe for all JavaScript?
No. It is a simple snippet minifier and may not handle every syntax edge case.
Does it mangle variable names?
No. It only removes comments and obvious whitespace.
Is my code uploaded?
No. Minification runs in the browser.
