Reduce file size while preserving the transparent background your PNG needs.

PNGs with alpha channels and sharp graphics run big — squeeze them down while keeping the transparent areas transparent and the edges crisp.
Add the PNG files you want to shrink.
Choose how aggressive the compression should be.
Process the images and check that transparency survived intact.
Download the lighter PNGs for web use or upload limits.
Transparency-safe compression, batch support, and files that stay on your machine.
The alpha channel is preserved, so cutouts stay cut out after compression.
Flat-color screen captures and UI shots compress dramatically better than photos.
Portals with strict file-size caps take the slimmed PNG without complaint.
The compression targets wasted space, not the palette, so shades come through unchanged.
The compressed version downloads as a new file; nothing on your disk is modified.
PNG is a lossless format, so photographic detail is hard to shrink without altering pixels. Convert photo-like PNGs to JPG or WebP for serious savings.
Screenshots, icons, charts and anything with flat colors and large single-color areas, because there is more redundancy to squeeze out.
No. The alpha channel is carried through the process, so edges stay transparent in the output file.
WebP usually wins on size and also supports transparency. Keep PNG when maximum compatibility or guaranteed lossless quality matters more than weight.
