JavaScript Minifier
Paste JavaScript and get a smaller file that behaves the same. The minifier parses your code properly (it uses Terser), so it can remove dead code, shorten expressions and rename local variables safely, which regex-based minifiers cannot do. Everything runs in your browser; your code is not uploaded.
- Limits No daily limit on the page
- Where it runs Runs in your browser; nothing is uploaded.
- Cost Free, with the limits above. No account needed.
