JavaScript Formatter, Beautifier & Minifier

Make every script production ready

Search engines crawl the JavaScript you ship, so messy indentation and stray console statements can hide critical UX bugs. This formatter rewrites functions with balanced braces, aligned imports, and consistent spacing so you can review logic the same way a code reviewer would. Toggle between pretty-print and minified output to see how much render-blocking weight you can save before deploying to your CDN.

  • Normalize arrow functions and callbacks to expose unused parameters.
  • Quickly scan object literals and JSON configs without squinting at inline blobs.
  • Share minified snippets with marketing or SEO teams that embed scripts on landing pages.

Helpful tips

Paste the unformatted snippet, choose Format to inspect and edit, then click Minify to create a lightweight production copy.

Use the output panel’s copy shortcut to move code directly into Git commits, CMS widgets, or tag managers.

Pair this tool with the API Tester to verify that the endpoints your scripts call are returning cacheable, SEO-friendly responses.
