Reverse the animation
Flip the frame order so a short animated GIF plays backwards while keeping its dimensions.
Reverse GIF online →Private animation tools
Free GIF tools that run locally
Change animated GIFs in your browser without sending them to a server. Reverse playback, adjust timing or dimensions, rebuild the color palette, extract frames, or create a GIF from images.
What do you want to change?
Change speed or dimensions
Make the animation faster or slower, or resize it to a practical web width.
Change GIF speed →Reduce GIF size
Rebuild the color palette with fewer colors when a GIF is too large for sharing or embedding.
Optimize GIF →Export or create frames
Download every GIF frame as PNG, or combine ordered images into a new animation.

- MP4 to GIF Turn a short MP4 clip into a silent GIF for chats, previews, and simple embeds. The GIF is capped at 480px wide and 12fps so the file stays reasonable; long videos still make very large GIFs.
- WebM to GIF Create a silent GIF from a short WebM recording or browser capture. The conversion downscales output to at most 480px wide and 12fps, which keeps the GIF more shareable but makes it a poor fit for long clips.
- MOV to GIF Make a silent GIF from a short iPhone or camera MOV clip. The browser converts locally and downscales to at most 480px wide at 12fps so the result is easier to share.
- GIF to MP4 Turn an animated GIF into a silent MP4 video that is usually much smaller and plays more reliably in modern apps, browsers, and feeds.
- Resize GIF Set a new GIF width and keep the animation private.
- Optimize GIF Compress GIFs by rebuilding the color palette locally.
- Reverse GIF Flip a short animated GIF so it plays backwards.
- Change GIF Speed Speed up or slow down GIF timing with fixed presets.
- GIF Maker Create a GIF from reordered JPG, PNG, or WebP frames.
- GIF to Frames Export a GIF as one PNG download per frame.
What to expect from browser GIF processing
Heavier GIF operations use ffmpeg.wasm. Its roughly 31 MB engine downloads once per tab, then the selected animation is decoded and processed on your device.
Short, web-sized animations work best. Long or very large GIFs can consume substantial memory because the browser may need to hold many decoded frames before creating the output.
