1. Upload PNG images by dragging and dropping, browsing files, or pasting from clipboard
2. Adjust the color count slider to control compression level (2-256 colors)
3. Preview the before/after comparison to verify quality
4. Download individual compressed images or all at once as a ZIP file

Does PNG compression preserve transparency?

Yes. The compression reduces the number of colors but keeps the alpha transparency channel intact.

What color count should I use?

128 colors works well for most images. Use higher values for photos and lower for simple graphics.

Are my images uploaded to a server?

No. All compression happens entirely in your browser. Your images never leave your device.
