JPG, PNG and WebP compression

Upload JPG when you want a smaller photo, PNG when the source may include transparency, or WebP for an efficient web-ready format. The tool exports compressed images as WebP for smaller files or JPG for broad compatibility. When converting a transparent PNG to JPG, transparent areas are filled with white.

Online image compressor FAQ

Is this online image compressor free?

Yes. You can compress JPG, PNG and WebP images online for free, with no account required.

Are my images uploaded?

No. Everything happens locally inside your browser. Your original and compressed images never leave your device.

Which format should I choose?

WebP usually creates the smallest file for websites and modern apps. Choose JPG when compatibility with older software matters most.

Will compression reduce image quality?

A quality setting around 80% typically gives a much smaller file with little visible difference. Adjust the slider to suit your image.

Does PNG transparency stay transparent?

Yes when exporting to WebP. JPG does not support transparency, so transparent areas are placed on a white background.
