How to Resize a GIF
FastEdit resizes animated GIFs locally in your browser. Use it to make a GIF fit a chat app, crop it for a platform ratio, reduce file size, or export a smaller animated WebP without uploading the original file.
Walkthrough
- 01
Open FastEdit
Go to fastedit.net. No install, account, or upload step is required.
- 02
Drop your GIF
Drag and drop the animated GIF into the editor. FastEdit loads the frames locally and preserves the animation timing.
- 03
Set the new dimensions
Open Resize and enter the target width or height. Keep aspect ratio locked unless you intentionally need a stretched output.
- 04
Crop if the shape needs to change
Use Crop when the GIF needs a square, vertical, or widescreen layout. Scrub the timeline to confirm the subject stays in frame.
- 05
Choose GIF or WebP output
Export as GIF for maximum compatibility, or animated WebP for smaller files and better color on modern platforms.
- 06
Check the exported size
If the target app has a file size limit, export once and compare the output size. If it is too large, reduce dimensions, frame rate, or quality.
Small things worth checking
- Resizing is one of the fastest ways to reduce GIF size because it removes pixels from every frame.
- For chat apps, 320-480px wide is usually enough. Larger dimensions often add file size without improving how the GIF looks in the message.
- Use Crop before Resize when you need a different aspect ratio. Resizing alone changes dimensions, not composition.
- If the resized GIF is still too large, lower frame rate, reduce quality, or trim the animation shorter.
- Use animated WebP when the destination supports it. It usually produces smaller files than GIF at the same visual quality.
