Compress PNG for free without losing transparency
Make your PNG logos, screenshots, icons and illustrations lighter. The tool reduces the colours to a palette of 256 or fewer, with optional dithering, keeps transparency and saves a palette PNG. If your PNG does not get smaller, you get the original back.

HOW TO USE IT
Three steps.
Add your PNGs
Drop or choose up to 10 still PNGs of up to 30 MB and 40 megapixels.
Choose the colours
With 256 colours, logos and screenshots usually look the same; with fewer, the file is smaller. Dithering smooths gradients.
Download
You will see the size before and after for each PNG. Download them one by one or in a ZIP.

Compress PNG: common questions
Does it lose quality?
If your PNG has more colours than the chosen palette, it changes slightly: similar colours are merged. If it already has that many colours or fewer, it comes out identical pixel for pixel.
Is it good for photos?
A PNG photo has thousands of colours and the reduction may show. For photos a JPG or WebP is usually smaller: use “Compress image”.
Which browsers support it?
Those with built-in compression (CompressionStream): current versions of Chrome, Edge, Firefox and Safari. If yours lacks it, the tool tells you.
Are my images uploaded to a server?
No. The tool runs inside your browser: files are read and processed on your device and are not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
