How to Compress PNG Online
Compress PNG makes a PNG smaller while keeping its transparency. PNG cannot throw away detail the way JPG does, so the saving comes from using fewer colours, which works well on screenshots, logos and flat graphics. You choose a quality level or type a target size in KB, and the page shows the estimated result before you save.
Reduces PNG size while keeping transparency. PNG compression is lossless, so the savings come from reducing the palette — which works very well on screenshots, logos and flat graphics, and poorly on photographs, where a lossy format is the better answer.

Tips and Good to Know
-
Photographs do not compress well as PNG. A photo that must be under a size limit should go through Compress Image as a JPG instead.
-
Fewer colours means banding in smooth gradients and soft shadows. Check the preview slider on anything with a sky or a blurred background.
-
If the target size is smaller than the picture can reach without becoming unreadable, the page says so and shows the smallest it managed.
Frequently Asked Questions
Answers to common questions about this tool.
Do I need to install anything to compress PNG?
No. Compress PNG runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.
Is it safe to compress PNG online?
Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.
Does Compress PNG reduce my photo’s quality?
Converting and cropping keep quality close to the original. Compressing trades a little detail for a much smaller file, and a lighter setting keeps more of it. Compare the preview with your original before saving.
Will my photo be accepted by the exam form?
The exam photo tools follow the size, dimensions and file weight given in the official notice. Always read the latest notice too, because boards sometimes change their rules between years.
Can I edit pictures with Compress PNG straight from my gallery?
Yes. Pick a photo from your gallery or take one with the camera, then save the result back to your phone. Everything works in the browser, so there is no app to install.
Is Compress PNG free with no watermark?
Yes. Use it for as many pictures as you need without an account, and each image comes back without any logo or mark from the site.
