Frequently asked questions

Which formats are supported?

The converter accepts JPG, JPEG, PNG, and WebP and outputs JPG, PNG, or WebP.

Can I convert an image to the same format?

No. The matching source format is disabled because this tool is intended for format conversion.

How are transparent pixels handled in JPG?

JPG does not support transparency, so transparent pixels are placed on a white background.
