Use this JavaScript Minify tool to compress readable JavaScript into a smaller compact form. It is useful for reducing visual clutter, preparing snippets for embedding, creating one-line test fixtures, and turning formatted code into tighter output for quick developer workflows.
Example pages are especially useful for developer tools because they show what good input looks like, what kind of output to expect, and how the tool behaves in common scenarios.
