Cut the size of screenshots, logos and graphics by reducing their color palette, the same technique used by TinyPNG. Transparency is preserved, and you check the result before you download.

PNG is compressed by reducing its color palette. A lower quality means fewer colors and a smaller file.
Runs fully in your browser. Your files are never uploaded.
Drop, paste or choose one or many JPG, PNG, WebP or other images. Nothing is uploaded; every file stays on your device.
Use the quality slider, or switch to target size and enter a limit such as 100 KB. You see the before and after size and a side-by-side preview.
Save each compressed image, or download them all at once as a ZIP file. Files that cannot get smaller are returned unchanged.
Your files are processed on your device and never uploaded to any server.
No account, no limits and no watermark on your results.
Runs at native speed in your browser and keeps working once the page has loaded.
You choose the settings - nothing is silently downscaled or recompressed.
The compressor quantizes the image, replacing the millions of possible colors with a palette of up to 256 well-chosen ones. This is usually invisible and can shrink a PNG by 60-80%.
Yes. The alpha channel is part of the quantization, so transparent and semi-transparent areas are kept.
Around 80-90 works well for screenshots and illustrations. Photos with smooth gradients may show banding at low settings, so lower the value step by step.
Set quality to 100 and the pixels are kept exactly, only the file is repacked more efficiently. The saving is smaller than with the palette method.
