Compress PNG Images
Shrink PNG screenshots and graphics, or convert them to WebP for a much smaller file. Runs locally in your browser with no upload.
Runs entirely in your browser — your file is never uploaded.
Questions
- Will transparency be preserved?
- Yes, when you keep the output as PNG or WebP. Both support an alpha channel; converting to JPEG would not.
- My PNG barely got smaller. Why?
- PNG is already lossless-compressed, so photographic content has little left to give. Converting to WebP or JPEG usually saves far more.
