About this tool
PNG files can be big, especially screenshots and graphics. This compressor shrinks them by reducing the number of colors with an intelligent palette while keeping transparency, the same technique used by TinyPNG.
The result appears next to the original size so you can see the saving immediately. Choose "PNG lossless" if you need an exact copy.
Everything is processed inside your browser, which means no uploads, no queue and complete privacy.
Frequently asked questions
How do I compress a PNG image?
Add the PNG file, set the quality and download the smaller version.
Will compressing a PNG reduce quality?
PNG compression here reduces colors very subtly. Choose PNG lossless for zero change.
How small can a PNG get?
It depends on the picture, but 50 to 90 percent savings are common.
Is PNG Compressor really free?
Yes. You can use PNG Compressor as often as you like with no sign-up, no watermark and no daily limit.
Are my images uploaded to a server?
No. PNG Compressor runs entirely in your web browser, so your files stay on your own device and are never sent to DEWANARO or anyone else.
