Minifying removes spaces, comments and line breaks from code, so files are smaller and download faster. The code behaves the same.
Why it matters
Smaller files mean quicker loading, which helps visitors and is part of how page speed is judged.
Tools
- JS Minifier for scripts.
- HTML Compressor for page markup.
Do it safely
- Keep your original, readable files as the source.
- Minify a copy and test the page afterwards.
- Check your speed before and after with the Page Speed Checker.
Combine this with compressed images and caching for the biggest gains.
