PNG compressor for transparent images

PNG is the right choice for transparency, screenshots, UI graphics, icons, and flat-color artwork. This page reduces PNG size while keeping PNG output.

PNG compression is different from JPEG compression

PNG compression often relies on metadata cleanup, lossless optimization, and optional color reduction. Higher quality settings preserve more color detail.

Keep PNG compatibility

Use this page when your workflow requires PNG after compression. If smaller modern delivery matters more, convert PNG to WebP instead.

FAQ

Does PNG compression keep alpha transparency?

Yes. PNG transparency is preserved.

Some PNG files are already optimized. Screenshots and flat graphics usually compress better than photo-like PNGs.

Should photos use PNG?

Usually no. JPEG, WebP, or AVIF are normally better for photos.
