Tip: JPG and WebP support adjustable visual quality. PNG uses lossless encoding in most browsers, so its quality slider may not noticeably reduce file size. Try WebP or set smaller dimensions when you need a smaller PNG. Converting transparent images to JPG fills transparency with white.

Frequently asked questions

Will compressing reduce my PNG quality?

You control the trade-off with the quality slider. At high quality the difference is invisible while files can shrink dramatically.

Why are my PNG screenshots so large?

Screenshots save every pixel losslessly. Our compressor re-encodes them efficiently — screenshots often shrink 50-80% with no visible change.

Is there a file size limit?

Processing happens in your browser's memory, so keep individual files under about 100 MB for smooth performance. There is no server-side limit.

Are my PNGs uploaded anywhere?

No. Compression runs 100% on your device. Your images never leave your browser.

PNG or JPG — which should I compress to?

Keep PNG for graphics, logos, and screenshots (sharp edges). For photos, convert to JPG first, then compress — you will get far smaller files.
