Beautify vs minify JavaScript: when to use each

Beautify and minify are opposite ends of the same free online JavaScript workflow. Beautify restores readable structure; minify strips unnecessary whitespace to shrink size.

When to beautify

• Debugging minified vendor scripts
• Reviewing pasted one-liners
• Preparing snippets for humans to edit

When to minify

• Smaller embeds and bookmarklets
• Reducing transfer size for simple scripts
• Quick compress before sharing a payload

Use both free online tools

Start with the free online JavaScript beautifier to read code, then the free online JavaScript minifier to compress. Lint first if syntax looks broken.
