How to use it
- Drag your images into the box or select them from your device. It accepts JPG, PNG, WebP, AVIF, GIF, BMP, HEIC, and TIFF, up to 50 at a time.
- Check the result in the viewer: the original is on the left and the compressed image on the right. Drag the divider to compare, and zoom with Ctrl + scroll (⌘ + scroll on a Mac), with two fingers, or with the zoom buttons. Double-click to switch between fit and 100%.
- Move the quality slider, pick a shortcut (Web, Email, Best quality, or Smallest size), or set a format, a size, or a maximum file size. Every change shows up instantly, with the new file size and the percentage saved.
- Go through the batch in the image strip. If one image needs different treatment, select it and turn on “Adjust only this image.”
- Download the image you are viewing, or all of them together in a ZIP, from the summary bar.
Frequently asked questions
How do I compress a PNG without losing quality?
With the “Lossless” option. The PNG is saved the same but lighter. There is also “Optimized,” which is a bit slower, and “256 colors,” which reduces much more with a slight loss in gradients.
When should I use PNG and when JPG?
PNG is better for logos, screenshots, and images with transparency. For photographs, JPG or WebP are much smaller, because PNG does not compress photos with loss.
Is transparency kept?
Yes. PNG keeps the transparent areas. If you convert to JPG those areas are filled with a background color, which is why you stay on PNG here.
Compress PNG and keep transparency
PNG is ideal for logos, screenshots, and images with a transparent background, but photos in PNG get large. This page sets the output format to PNG so you can choose the compression level: lossless, optimized, or 256 colors. None of them breaks transparency.
Which option to choose
“Lossless” is the fastest and safest. “Optimized” takes a little longer and usually saves some. “256 colors” cuts the size a lot but can cause banding in gradients. If the PNG does not shrink enough and you do not need transparency, consider WebP. For photos use compress JPG or go back to the image compressor.
