Creating Animated GIFs
GIF (Graphics Interchange Format) is a bitmap image format that supports animation and simple transparency. Despite being replaced by modern formats for static images, GIF remains popular for short animations due to wide compatibility.
How to Use This GIF Maker
Upload multiple images or frames in PNG, JPEG, or WebP format. Set the frame duration (how long each image displays). Arrange frames in the desired order. Click Generate to create the animated GIF. Adjust settings and regenerate as needed.
▶Why are GIF files so large?
GIF uses limited color palette (256 colors max) and no compression for animations. For modern web use, consider using WebP or AVIF animations which offer better compression and quality.
▶What's the optimal frame duration?
Common durations are 100ms (10fps) for smooth animations, 200ms (5fps) for simple effects, or 500ms-1000ms for slide shows. Shorter durations create smoother motion but increase file size.
▶Can I edit an existing GIF?
This tool creates GIFs from static images. To edit existing GIFs, you'd need to split them into frames first, then reassemble with this tool.
