Characteristics of GIF format
GIF supports animation and transparent background, but is limited to 256 colors. Suitable for simple animations, memes, and images with fewer colors, but the file size is relatively large.
Principles of GIF compression
GIF compression mainly reduces file size by decreasing the number of colors, optimizing the palette, and removing redundant frames. Despite its limitations, it can significantly reduce file size.
For static images, it's recommended to convert to JPEG/PNG/WebP. For animations, consider WebP animation or video formats for smaller file sizes and better effects.
Reducing the number of frames, lowering resolution, and limiting the number of colors can effectively decrease GIF size. For complex animations, consider using video formats instead.
GIF is still widely used for memes, simple animation demonstrations, and social media. Although not the optimal format, it has excellent compatibility and is supported by almost all platforms.
Modern projects are advised to use WebP animation, APNG, or directly use video.
