Safety notes

  • GIF is inert, but huge GIFs can lock up browsers (the classic 'GIF bomb'). Treat unsolicited very large GIFs with caution.

Common mistakes

  • Saving photos as GIF dithers them into 256 colours. JPEG or WebP is the correct choice for photographic content.
  • Animated GIFs are 5-10x larger than an equivalent MP4 — switch to WebP or MP4 for delivery.
