GIF (Graphics Interchange Format)

GIF (Graphics Interchange Format) is a bitmap image format from 1987 that supports a palette of up to 256 colors per frame, single-bit transparency, and simple frame-by-frame animation.

Why it matters

GIF remains popular for reaction images and short loops because it plays everywhere without a player. Its limitations are large file sizes for longer clips and poor color for photos. Short MP4 or WebM video with autoplay and loop usually produces much smaller files than an equivalent GIF.

The name is commonly pronounced both ways.

Example

$ ffmpeg -i demo.gif -movflags faststart -pix_fmt yuv420p demo.mp4

This converts an animated GIF to MP4. The video is typically a fraction of the original size, which helps page speed.

Common mistakes

• Using large animated GIFs on web pages and slowing loading.
• Expecting smooth gradients; 256 colors causes banding.
• Using GIF where a PNG or SVG would give better quality.
