What the PNG Compressor does
Reduce PNG file size while preserving crisp edges and transparency where possible.
Shrink PNG files while keeping edges crisp and transparency where it survives.
Why the PNG Compressor is useful
Large PNGs can slow page loads and consume storage, especially for interface graphics and screenshots.
Interface screenshots and diagrams are often far larger than a page needs, and trimming them speeds up every load that follows.
Also known as: png compressor, compress png, shrink png, free png compressor, online png compressor, png compressor online free, png compressor tool.

Tips for the best results
- For photographs, compare WebP or JPEG because PNG is often less efficient for continuous-tone images.
- Text-heavy images tolerate less compression; check letters for fringing before saving.
Conclusion
Archive the original PNG, because a compression level that suits one layout may not suit another.
