Conversion

In case the images are used in other plugins, problems may occur after converting them, if these plugins use the absolute URLs of the images. There will be no issues in case they use the media IDs of the pictures.

Enable conversion

JPG to PNG conversion

PNG uses lossless compression. It is recommended to use for logos, and other pictures with transparent backgrounds. This option removes image metadata and increases CPU usage.

JPG to WebP conversion

WebP lets you have 25-34% smaller images and speed up your website. JPG to WebP conversion is lossy, but it will not affect the image quality significantly.

PNG to JPG conversion

JPG format is recommended to use for photographs and similar high-resolution images. Since it uses lossy compression, some of the image data is lost when the image is compressed.

PNG to WebP conversion
