GIF FAQ
Is GIF better than JPEG?
Depends on the job. GIF is animation format with limited colors, and large for full-color photos because of the 256-color limit. JPEG still wins when you need guaranteed support everywhere, such as in email clients or legacy software.
Does GIF support transparent backgrounds?
Yes. GIF stores an alpha channel, so logos, icons, and cut-out graphics keep their transparent areas intact.
How large is a typical GIF file?
large for full-color photos because of the 256-color limit. Actual size always depends on image content and quality settings — a detailed photograph and a flat two-color logo in the same format can differ by an order of magnitude.
