What Happens to the Background of a GIF

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Check the first image's size
  • Check the margins
  • Match sizes first if needed

Make an Animated GIF fills the background with white rather than making it transparent.

Steps

  1. The first image sets the GIF's overall size
  2. Images of other sizes get white margins
  3. Crop images first to match them neatly
Using images of the same size avoids margins.
