Does resizing distort the animation's proportions?

No — only the width is set directly; height is calculated automatically to preserve the original aspect ratio, so the animation isn't stretched or squashed.

Does resizing reduce the file size too?

Yes, generally — fewer pixels per frame means a smaller file, though the exact reduction depends on the animation's content and how much the width actually shrinks.

Can I make a GIF larger instead of smaller?

Yes — enter a target width larger than the original, though enlarging a GIF beyond its original resolution will look softer since no new detail is being added.

Is my GIF uploaded to a server?

No — resizing happens entirely in your browser using WebAssembly. Nothing is uploaded anywhere.

Resize a GIF to a Different Width, Keeping the Animation

Need to use GIF Resizer right now?

An animated GIF sized for one context — a full-width blog embed, a large messaging preview — often needs to be smaller for a forum signature, a smaller widget, or a size limit imposed by a platform. Resizing an animated GIF isn't as simple as resizing a static image, since every frame needs to be resized consistently while preserving smooth playback.

About GIF Resizer

This tool resizes every frame of an animated GIF to a target width you specify, automatically scaling the height to preserve the original aspect ratio, and rebuilds the animation using a freshly generated color palette so quality stays sharp even after resizing down.

Processing runs through FFmpeg compiled to WebAssembly, running entirely in your browser — the resize happens locally, with no upload wait and no file size limit imposed by a server.

How it works

Upload your GIF. Choose the animated GIF you want to resize.
Set the target width. Height scales automatically to match the original aspect ratio.
Download the resized GIF. Get the same animation at the new size.

Examples
