Compress PNG Images
Make PNG screenshots, logos and graphics much lighter for websites, email and online forms. They stay PNG files with their transparent background, saved with fewer colors. Add one image or a whole batch; your images never leave your device.
How to use Compress PNG Images
- Select one or more PNG images.
- Choose a quality, or a maximum file size in KB.
- Start the compression. One image downloads directly; several images download as a ZIP file.
Frequently asked questions
How can a PNG get smaller?
PNG is lossless, so the image is reduced to a palette of at most 256 colors chosen from the picture itself. Screenshots, logos and drawings often lose more than half their size with no visible change. A lower quality uses fewer colors; smooth gradients may then show bands.
Is the transparent background kept?
Yes. Transparent and semi-transparent pixels stay as they are, so a logo or sticker still fits on any background.
What about photos?
A photo saved as PNG usually gets much smaller as a JPG. If it has no transparency, choose JPG as the format, or use Compress JPG.
Are my images uploaded?
No. The images are compressed in your browser, so they never leave your device.
