Resize GIF

Rescale an animated GIF to any width
Sometimes a GIF is simply the wrong size — too wide for a comment thread, too tall for a signature, or too big to sit neatly in a slide. This resizer scales every frame of an animated GIF to the width you choose, working the height out automatically so the proportions stay perfect and nothing looks stretched.
Because fewer pixels per frame also means a lighter file, resizing down is one of the quickest ways to make an oversized GIF load faster and send more easily. Everything runs locally in your browser using the canvas, so your animation is never uploaded and the frame timing and loop are carried over untouched.
How to resize a GIF
- Drop your GIF into the box above (or click to choose one).
- Type the new width in pixels — the height updates automatically to match.
- Preview the resized animation to check it looks right.
- Click Resize & download GIF to save it.
Why resize a GIF?
Fit it to the space
Set an exact pixel width so the GIF sits properly in a chat, an email signature, a README or a slide instead of overflowing the layout.
Shrink the file at the same time
Scaling down reduces the number of pixels stored per frame, which is one of the most reliable ways to cut a GIF's file size without touching the animation itself.
Aspect ratio stays correct
You only set the width; the height is calculated for you, so the animation never ends up squashed or stretched.
Frequently Asked Questions
Are my GIFs uploaded to a server?
No. Resizing happens entirely in your browser — your GIF never leaves your device, so it is safe for private or unpublished animations.
Do I have to set both width and height?
No. You enter a new width and the height is calculated automatically to keep the original aspect ratio, so the animation never looks stretched or squashed.
Can I make a GIF larger as well as smaller?
Yes, though scaling up cannot add detail that was not there. Enlarging a small GIF looks softer; resizing down keeps things crisp and also reduces the file size.
Does resizing keep the animation and timing?
Yes. Every frame is scaled to the new dimensions and the frame delays and loop are preserved, so the GIF plays exactly as before at its new size.
Will resizing make my GIF smaller in file size?
Usually, yes. Fewer pixels per frame means less data, so scaling a GIF down is one of the most effective ways to shrink its file size.
