Smaller Files = Faster Websites
Every kilobyte matters for web performance. Minification removes whitespace, comments, and unnecessary characters from code without changing how it works. The result? Files that download faster and pages that load quicker.
What Gets Compressed
JavaScript — Remove whitespace, shorten variable names, strip comments. Typical savings: 30-60%.
CSS — Eliminate formatting, combine rules, optimize colors. Typical savings: 15-30%.
HTML — Remove unnecessary whitespace between tags. Typical savings: 10-20%.
SVG — Strip metadata, optimize paths, reduce precision. Can shrink files dramatically.
Why It Matters
Faster sites rank better in Google. Users on slow connections appreciate smaller downloads. Mobile users benefit from reduced data usage. Minification is a quick win for performance.
Safe Compression
Minified code works identically to the original — just smaller. Process sensitive code privately in your browser without uploading to external servers.
