04 / FAQ
Simple and transparent.
Does Qingtu save or upload my images?＋
No. JavaScript processes images locally in your browser. They are never sent to our servers, and results clear when you refresh or close the page.
Why can the result be smaller than my target?＋
The target is a maximum. Qingtu preserves as much quality as possible without exceeding it, so the final file may be slightly smaller.
Why is PNG harder to compress to an exact size?＋
PNG is lossless, so quality cannot be tuned like JPG or WebP. Choose JPG when you need a strict size limit.
