GIF Resizer

This GIF resizer changes the size of an animated GIF and keeps its animation. Type the width and height or pick a percentage; nothing is uploaded.

Examples

GIF Resizer result: Halloween GIF resized from 512×512 to 256×256 at 50%, 1.09 MB to 379 KB

How to resize a GIF in three steps

Using this GIF resizer takes a file, a size and one click.

  1. 1

    Add your GIF

    Click the file picker or drop the GIF on the preview. It opens in your browser and is not uploaded.

  2. 2

    Set the new size

    Type a width or a height, or tap 25%, 50%, 75%, 150% or 200%. With Keep aspect ratio on, the other side follows. Turn it off to stretch.

  3. 3

    Resize and download

    Press Resize GIF. The result line shows the size before and after, the new pixel size, frames and time taken. Download saves the GIF, or Start over loads another.

Resize a GIF to lower its file size

The GIF resizer reduces the dimensions of every frame. Width and height decide the file size more than any other setting, which is why a smaller GIF is the first thing to try when a file is too heavy.

In our test, a 640 x 360 GIF of 150 frames and 19.9 MB became 5.52 MB at 50% in 1.9 seconds on Chrome for macOS. A 115 MB GIF went to 960 px wide in 9.3 seconds. Your numbers depend on the GIF and your device, and the result line shows yours.

Enlarge, stretch or crop instead

You can enlarge a GIF to 150% or 200%, up to 4096 px on a side, but resizing cannot add detail the frames never had, so it looks softer. Scaling down is the better direction.

In the GIF resizer, turn Keep aspect ratio off only when you want a stretched look; every frame is distorted the same way. If you need to cut part of the picture away rather than scale all of it, crop first and resize after.

What this GIF resizer does not do

It scales pixels and nothing else. There are no platform presets, so you type the size you need. There is no crop or padding to fit a new shape, and no change to speed or frame rate. GIF goes in and GIF comes out; for MP4 or WebM you need a converter.

For a target file size, a compressor with a size field fits better. For a different frame, crop first, then resize the cropped GIF here.

Frequently asked questions

Add the GIF, type a new width and height or tap a percentage, then press Resize GIF and download. Every frame is scaled, so the animation stays.

No. This GIF resizer runs in your browser on your device, and the file is never sent to our server.

Every frame is stored as a picture, so a GIF with many frames or large dimensions adds up fast. Lowering the width and height shrinks all frames at once.

Resize it smaller first and check the result line for the new size. This tool has no target file size field. The GIF compressor on this site has a 256 KB target.

Scale it down. In our test, 50% turned a 19.9 MB GIF into 5.52 MB. If it is still too big, run the result through the GIF compressor.

Resize when you need other pixel dimensions or a quick drop in file size. Compress when the size is right but the file is heavy. Resizing changes how big the GIF looks; compressing changes how many bytes it takes.

Up to 4096 pixels on each side. We set no file size limit, and a 115 MB GIF resized in our test, though very large files need a lot of memory.

Yes. All frames are resized and the result is still an animated GIF. It is not a replacement for checking the playback before you share it.

Yes. Turn Keep aspect ratio off and set width and height separately in the GIF resizer. A 500 x 100 stretch worked in our test.

In our test, a transparent sticker kept its transparency after resizing.

Match the place it will show, and check that platform's current size rules.

Yes. There is no sign-up, no watermark and no limit on how many files you resize.
