GIF (Graphics Interchange Format) uses lossy (limited to 256 colors) encoding and is best for simple animations, memes, and images on platforms that support animated GIFs natively. MP4 (MPEG-4 Part 14) uses lossy compressed encoding and excels at universal video playback on any device — phones, smart TVs, web browsers, and social media. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing.
