How to resize an animated GIF
- Drag and drop your GIF (up to 50 MB) onto the upload area, or click to browse.
- Enter the new width in pixels. Leave Maintain aspect ratio on to fill in the height automatically.
- Click Resize GIF. A progress bar shows decoding, frame resizing, and re-encoding stages.
- Preview the result side-by-side with the original, then click Download.
Tips for the best result
Resize down, never up. GIFs use indexed-color frames; upscaling reveals color banding and won't add detail. If you need a larger output, consider re-rendering the source video instead.
Pick dimensions in multiples of 2. Some downstream tools (Twitter, MP4 converters) prefer even dimensions. The GIF resizer will accept any value, but choosing 600×400 over 601×401 avoids surprises later.
Lower quality = smaller file. The default quality (10) is a good balance. Increasing the number trades visual fidelity for file size.
Common use cases
- Social media: Reddit, Discord and Slack each enforce different GIF dimensions. Resize to fit.
- Documentation: README files and product docs look cleaner with consistent GIF widths (e.g., 720 px).
- Email signatures: Tiny animated icons (e.g., 80×80) without re-exporting from After Effects.
- Presentation slides: Match the GIF to the slide's content area.
FAQ
Will resizing make the file smaller? Usually yes — fewer pixels per frame means a smaller payload. Compression also depends on the source GIF's color complexity.
Does the animation play at the same speed? Yes. We preserve every frame's original delay.
Does it work on transparent GIFs? Transparency is preserved when re-encoding.
