Why compress your PNGs?
PNG is the go-to format for logos, icons and anything that needs a transparent background — but those files can get heavy. Large images slow your site down, hurt your Core Web Vitals and eat into mobile data. Because search engines factor page speed into rankings, lighter images can quietly help your SEO as well as your users.
This compressor reduces file size by optimising the colour data while leaving the transparent (alpha) channel untouched, so your cutout still drops cleanly onto any background. Flat illustrations, icons and screenshots usually shrink the most — often 40–70% — while richly detailed photos compress a little less.
Everything happens in your browser, so there’s nothing to upload and no cap on how many PNGs you can process. Slide the quality control, watch the savings update live, and download once the balance of size and detail looks right.
