Frequently asked questions
How much smaller will my file get?
Typically 20–60% before compression, depending on how much whitespace and commenting the source contains. The tool reports the exact saving.
Should I minify if my server uses gzip?
Yes. Minification and gzip compound: minifying first removes content gzip would otherwise have to encode.
