About this tool
PNG Compressor
Reduce a PNG image’s file size while retaining transparent areas. The tool re-encodes the image in your browser and shows the original size, new size, and percentage saved before you download.
PNG works well for logos, interface graphics, screenshots, and images that need transparency. Photographs without transparency are often smaller as JPG or WebP.

Common questions
PNG Compressor FAQ
Will transparency be preserved?
Yes. The compressed output remains PNG and retains transparent and semi-transparent pixels.
Why is my PNG still large?
PNG is lossless and can be inefficient for photographs or complex gradients. Resize unnecessary dimensions or convert to WebP when a smaller lossy format is acceptable.
Does compression change image dimensions?
No. This tool keeps the same pixel width and height. Use the image resizer when the dimensions also need to change.
