How to compress a PNG losslessly

Choose a PNG

Choose a static PNG up to 40 MB and 16 million pixels. APNG is rejected. Readable EXIF is retained; only EXIF with orientation 1 is removed.

Compress

The tool checks PNG structure and decoding, recompresses image data, and removes only nonvisual metadata.

Check the result

Actual byte counts and a download appear only when the new file is smaller.

Are transparency and pixels preserved?

Yes. PNG image data is recompressed losslessly without canvas redraw. Transparency and color profile remain intact.

Can I hit a specific KB size?

No. Lossless PNG savings depend on the source. For a size limit with format change, use the target-size tool.

Is the image uploaded?

No. Selection, checks, and compression run in your browser.
