Compress PNG Images: what to know
PNG is lossless, so the usual compression tricks don't shrink it much. The big win is color reduction: most screenshots, logos and illustrations need far fewer than the 16 million colors a PNG can hold.
JustYourImage reduces the color palette to shrink the file while supporting transparent and semi-transparent pixels. Savings vary by image. Inspect gradients and fine detail because palette reduction can change colors.
Popular uses
- Screenshots for documentation and support
- Logos and icons with transparent backgrounds
- UI images and illustrations for websites
- Diagrams and charts
Tips for the best result
- Photos saved as PNG are huge. Convert them to JPG or WebP instead.
- If gradients look banded, raise the quality slider for more colors.
- Set quality to 100 for a lossless PNG that keeps every color.
