Compress image: common questions
How much smaller will it get?
It depends on the photo. A phone photo in JPG usually drops below half its size at 70–80% quality. If an image is already optimised and the copy is not smaller, you get the original.
What happens to PNG files?
In automatic mode, PNG and WebP are saved as WebP, which keeps transparency and is much smaller. If your browser cannot create WebP, the PNG is kept.
Can I ask for an exact size, like 100 KB?
Yes: choose “By target size” and type the KB. We look for the highest quality that fits; if it still does not fit, the image dimensions are reduced a little and we tell you.
Are my images uploaded to a server?
No. The tool runs inside your browser: files are read and processed on your device and are not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
What are the limits?
JPG, PNG or WebP up to 30 MB and 40 megapixels per file, not animated. Files are processed one at a time so the tab stays responsive, even on a phone.
