Questions
Can I convert many images at once?
Yes. Add up to 40 images, convert them with the same settings and download them together as a ZIP file.
What happens to transparent areas?
PNG, WebP and ICO keep transparency. JPG and BMP cannot, so transparent areas are filled with white or the color you choose.
