How do I know which file (jpg, tif, gif) to save my logo designs under?
The answer to this is provided in the software’s help section. To give you the short version: JPG should be used if the logo contains “real images” like people or scenery; GIF should be used if the logo is a flat toned image, like a cartoon. It all has to do with compression. Most of the logos created with The Logo Creator are no more than 40k no matter what format you choose to save it with.
