Compress PNG Online
Compress PNG online for screenshots, transparent artwork and diagrams. Keep PNG output while adjusting palette quality or a file-size target. Review sharp text, color gradients and transparent edges before downloading the result.

PNG savings depend on image content and mode
PNG compression can improve how pixel data is stored without requiring a JPEG export. Screenshots and flat graphics behave differently from detailed photographs. Klyvero offers lossless optimization and optional lossy palette reduction, with transparent output where supported. Palette changes can alter colors, so inspect gradients and fine edges and distinguish them from strictly lossless processing.
Convert an image to WebP when the destination accepts another format and PNG remains too large.
How to use Compress PNG
Choose input
Choose up to 20 PNG screenshots or graphics.
Review settings
Use quality 100 to keep decoded pixel colors, or lower quality for a smaller palette. Set a byte target if needed.
Save results
Compare small text and transparency, check the reported size, and download the PNG result.
Tips for Compress PNG
Lower PNG quality reduces the color palette and can cause banding in gradients. Quality 100 preserves decoded pixel colors at unchanged dimensions but does not preserve metadata or guarantee a smaller file. Target mode may lower quality or dimensions; inspect the result.
A transparent logo may compress well with a smaller palette, while a gradient-heavy screenshot may show visible bands. Compare both at full size and keep quality 100 if the reduced palette damages the artwork.

Compress PNG: frequently asked questions
What to know before you go.
Is PNG compression always lossless here?
No. At quality 100 and unchanged dimensions, decoded pixel colors are kept. Lower quality reduces the palette, and target mode can also reduce dimensions if allowed.
Will PNG transparency remain?
PNG output supports transparency. Inspect partially transparent edges after palette optimization to make sure the result suits your background.
Why is the PNG still above my target?
Detailed graphics and minimum format overhead can prevent a target from fitting. Check Over target, allow smaller dimensions or choose a larger budget.
Can I use an animated PNG?
Re-encoding produces a still image. Common APNG input is detected with a warning, but detection is best effort. Keep the original when animation matters.
Why can lossy PNG optimization change the colors in a screenshot?
Palette reduction represents the picture with fewer colors, which can change gradients and subtle edges. Use lossless mode when preserving decoded pixels matters more than further savings, and compare the result before replacing the source.
