PNG Compressor
Optimize PNG logos, screenshots and graphics while keeping PNG output. Compare lossless optimization with clearly labelled palette reduction, checking transparency and file size.
Get started
PNG Compressor — steps and download
Upload a transparent PNG. Use lossless mode to preserve colors or try palette mode for a smaller output. Check edges and gradients before downloading the PNG.
Why is there no PNG quality percentage?
PNG does not use a photographic quality percentage. Lossless mode preserves visible pixels; palette mode can reduce the number of colors. Compare the actual file sizes from both modes.
Frequently asked questions
Is PNG compression always lossless?
Lossless optimization preserves decoded pixels. Palette reduction can be lossy and must be a separate mode; a JPEG-style quality slider does not control PNG encoding in the same way.
