Compress
PNG optimizer
Reduce PNG size — or switch to WebP for far smaller files. Free, with no upload — your images stay on your device.
How to use the png optimizer
01
Drop your images onto the page — or choose files, a whole folder, or paste a screenshot.
02
Move the quality slider — or set a target size — and compare before and after side by side.
03
Download one file or the whole batch as a ZIP. Your project saves to Studio automatically.
Questions
Is the png optimizer free?
Yes — completely free with no file-size limit, because your own device does the work.
Are my images uploaded?
No. Your images are processed in your browser and never leave your device unless you save them to Studio.
Can I do many images at once?
Yes. Drop a folder or select many files — settings apply to the whole batch, and you can download everything as a ZIP.
