Does the image lose quality?

With medium compression, the difference is barely visible on screen. Lowering the maximum size, like to 1920 px, shrinks phone photos the most.

What does the automatic format do?

JPG photos stay JPG. Images with a transparent background become WebP, which keeps the transparency and is much smaller than PNG.

The tool never gives you a bigger file. If it cannot compress any further, you get the original image back.

Shrink images to send by email, upload to websites or save space. You see how much each file shrank before downloading.
