Minify JavaScript
How it works
Parsing and encoding run entirely in JavaScript here—no server sees your pasted content unless a tool explicitly says it fetches remote data.
Common mistakes
- Mixing tabs and spaces can change output alignment unexpectedly.
- Escaped characters may appear double-escaped after repeated transforms.
- Always verify output encoding before saving to production files.
Use this tool for
- Formatting or minifying snippets before pasting into a repo or ticket.
- Checking encodings (Base64, hex, URL) without third-party paste services.
- One-off developer checks during debugging.
Common questions
What should I double-check before trusting JavaScript Minifier?
Verify units, bases, and pasted text (hidden spaces or wrong line endings); then spot-check one example by hand if the answer must be exact.
Is anything I type sent to NexUtility servers?
Static assets load from the host once; your entries stay in the browser and are not sent to NexUtility for processing.
