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.
Readable JS, locally
It reindents simple snippets so structure like blocks and functions becomes visible; it is not a full parser. Formatting runs in your browser and never uploads anything.
Frequently asked questions
What does the lite beautifier do?
It adds line breaks after braces and semicolons and indents by nesting depth, which makes compact snippets readable.
What are its limits?
It is pattern-based, not a full parser. for loops and strings containing ; or braces can end up split oddly. Use Prettier for production code.
Does it change what the code does?
Only whitespace changes, so behavior stays the same.
