Upload an image

Select the image you want to use.

Where will you use it?

If the image size needed is not listed as an image dimension option at all, please select 'Custom' and input the required pixel dimensions.

Here's what you asked for

In some cases, an original .jpg or .png file can be converted to a .jfif file when downloaded to your computer. If this happens, once the image is downloaded and saved to your computer, please change .jfif with .png in the filename.

For example:
test-image.jfif should change to test-image.png

Doing this will ask you to verify if you want to proceed as it may make the image unusable, the image will not be affected and you can proceed.
