格式化与压缩 — About These Tools
Formatters and minifiers take messy or compressed code and turn it into something readable — or the reverse: shrink files to the smallest valid size for production. Every tool below parses your input in the browser and reprints it with deterministic, spec-compliant output.
常见问题
Are these formatters safe for private code?
Yes. Formatting and minification run entirely in your browser — your code is never sent to a server, logged, or stored.
What is the difference between formatting and minifying?
Formatting adds whitespace and indentation for readability; minifying removes every unnecessary byte to shrink the file. You need both: format while developing, minify before shipping.
Can formatter tools fix invalid syntax?
No. A formatter preserves your code exactly and only changes whitespace. If the input has syntax errors, the tool reports the error position instead of guessing a fix.
