The preferred image format is .png, as it has no compression artifacts and supports transparency. Ideally, every image uploaded to the Happy Tree Friends Wiki should use the .png format.

Since .JPG files are compressed files, the compression cannot be reversed, so there is no need to convert them to .PNG. If you are not able to obtain source .PNG pictures, you can simply upload them as .JPG.
