About this tool
PNG gets smaller in a browser mainly by resizing, because it has no JPEG-style quality slider. Flat colors, screenshots, and logos are what PNG is for. Photographs usually belong in JPEG or WebP if you need them small. Transparency can stay in PNG; a JPEG would put a solid background behind a logo, so do not switch formats by accident.
Compress PNG is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.
- No upload: the pixels never go to an image host.
- Speed: processing happens instantly on your device with no upload or download delays.
- Quality: you can check your file before saving, and the original remains unchanged.
