JS Beautifier Lite
Reindent simple JavaScript snippets for easier reading.
Reindent messy JavaScript
Minified or badly formatted JavaScript is hard to read and debug. This lightweight beautifier reindents simple snippets so the structure — blocks, statements, nesting — becomes legible again, making a compressed script workable.
It is a quick-reference reformatter for snippets, not a replacement for a full formatter in your build. Paste tangled JS, get a cleaner indented version, and copy it back to read or debug code you only had in a compact form.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
