Why use this tool?

Process minify javascript should be a 10-second job, not a 10-minute one. Most desktop apps want an installation, ask for an email, or stamp a watermark on the result. This tool does none of that — open the page, upload, get your .js, move on.

It runs from your browser, so you don't need to trust an unknown program with your files. The actual processing happens on our servers under a tight retention policy: files are auto-deleted within 24 hours and we never read, share, or train models on them.

How to process minify javascript

  1. Upload your JS, MJS (drag & drop or click to browse).
  2. Click Process and wait a few seconds.
  3. Preview the result on the page and click Download to save it.

That's it — no signup, no email, no waiting for an account verification.
