How to compress a PNG

  1. Drop your PNG files into the box above, or click to pick them.
  2. Choose the quality. A lower quality means fewer colors and a smaller file.
  3. Download each compressed PNG. Nothing is ever uploaded.

Why compress a PNG?

PNG files can be large, especially screenshots, logos and flat graphics. Compressing reduces the number of colors just enough to shrink the file a lot while keeping it looking good, and transparency is preserved. Tip: for photos on a website, converting to WebP usually gives an even smaller file.

Frequently asked questions

Is it free to compress PNG?

Yes. You can compress as many PNG files as you like, with no account and no cost.

Are my files uploaded to a server?

No. Everything happens inside your browser, so your files never leave your device.

Does it keep transparency?

Yes. The transparent areas of your PNG are preserved after compression.

Why did one file not get smaller?

Some PNGs are already optimized. In that case we keep your original file, so it never gets bigger.
