Frequently Asked Questions
No. The image is read, redrawn on a canvas in your browser and re-encoded there. Your file never touches a server, which is why there is no upload progress bar and no size limit from us.
It depends on the file. A JPG at the default setting typically drops by 40–80%. A PNG is lossless, so there the compressor flattens colours to fewer shades instead: a smooth graphic often shrinks by 80% or more, while a busy photograph may only lose a few percent at the default and needs the slider lower. The real saving for your file is shown before you download, and the tool says so plainly if a setting would make it bigger.
No. Dimensions stay exactly as they are. Use the Image Resizer if you want a smaller width and height as well.
Keep the original unless you have a reason. For sharing on the web, WebP is usually the best size at the same quality; for flat graphics and screenshots with sharp text and transparency, PNG is the right choice.
