Conservative CSSO settings
The default run removes comments and whitespace but keeps structural optimizations disabled to avoid risky stylesheet rewrites.
Intrare fragment și fișier
Paste partial CSS, full stylesheets, media queries, custom properties, or load a local .css file.
Măsurare sigură
Analytics use only size and reduction buckets. CSS source, URLs, selectors, comments, and filenames stay out of telemetry.
Întrebări frecvente
Is my CSS uploaded to Convertr?
No. The minifier runs locally with browser JavaScript. Pasted CSS and selected files are not sent to Convertr servers.
Why disable structural optimization by default?
Some aggressive CSS rewrites can change cascade behavior. The first version keeps compression conservative and focused on safe minification.
What happens when CSS has a syntax error?
The parser error is shown in the warnings panel so you can fix the stylesheet before copying output.
