Upload a GIF to see its frames.

Export every frame as a separate image (ZIP) or as one sprite sheet. Edits from the other tabs are applied to the frames.

Reuses pixels that barely change between frames. Higher values = smaller file, slight artefacts.

Browsers treat delays under 20 ms as 100 ms, so the fastest reliable speed is 20 ms per frame (50 fps).

How to use GIF Resizer

Resize a GIF without breaking the animation

Regular image editors only resize the first frame of a GIF or flatten it. This resizer applies the same resize, crop, rotation and flip to every frame, then re-encodes the animation with the original timing.

Crop to the perfect shape

Switch on Crop and drag a box on the preview, or pick a ratio: 1:1 for profile pictures and Discord emoji, 16:9 for videos and presentations, 9:16 for stories and 4:5 for Instagram posts.

Popular GIF sizes

  • Discord emoji: 128 × 128 px (keep it under 256 KB).
  • Slack emoji: 128 × 128 px.
  • Twitch emotes: 112 × 112 px.
  • Website banners: up to 800 px wide keeps files reasonable.

Need a smaller file as well? Use the GIF Compressor.

Frequently asked questions

Will resizing keep the animation?
Yes. Every frame is resized and the timing is kept.
How do I make a square GIF?
Switch on Crop, pick 1:1 and drag the square to the area you want.
Can I make a GIF bigger?
Yes, but enlarging cannot add detail, so the GIF may look soft. Making it smaller always looks sharp.
Is my GIF uploaded to a server?
No. The GIF is decoded, edited and re-encoded entirely in your browser. Nothing is uploaded, so it is private and works even offline once the page has loaded.
Is there a file size or frame limit?
There is no upload limit because nothing is uploaded. Very large GIFs (many hundreds of frames at high resolution) can use a lot of memory; up to 1,000 frames are loaded.
Does it keep transparency?
Yes. Transparent GIFs stay transparent, and the decoder handles all GIF disposal methods so frames are rebuilt exactly as browsers show them.
