About this tool
GIF resize tool will scale the width and height by the same percentage which means that the image won’t be stretched. If you set this to 100% then you will get the original size. If you set it to above 100% then you will get a larger image. If you set it to less than 100% you will get a smaller image. The preview will update to show you what your image will look like. Resizing will change the pixels in the image so it is often useful to make it smaller.

When resizing an image using percentages it will automatically preserve the aspect ratio. This is useful if you want to scale down your GIF for thumbnails/embeds/messages/layouts whilst keeping the image from appearing stretched. The percentage refers to how big the output will be relative to the input. 100% means no change, 50% means half the width and height. 200% means double the width and height.
Set it above 100% to make your animation appear larger on your page or preview. Set it below 100% to reduce the size of your canvas and often reduces file size. If you increase the scale, you won’t add any extra detail to your animation so you should consider how it will look when it is displayed at its final size. The output preview will automatically update to show how it will look. This makes it easy to see how it will look without manually processing.
The size of the image data will be greatly affected by the dimensions. By cropping the empty borders first you can reduce it further. If the colours are the main cause of a large file size then you can include palette compression. If you think you might need to use a different percentage then keep the original file. Each download will create a new output based on the source file and current control value.
Common questions
Choose the GIF, enter a percentage, and wait for the output preview to update. Download it when the dimensions look right.
100% keeps the original width and height. The output has the same dimensions as the input.
Yes. A value above 100% enlarges both dimensions while keeping the original proportions.
Yes. A value below 100% reduces the width and height proportionally.
Use a percentage below 100% to reduce the canvas, then check the output preview. Compression can reduce the file further.
Resize the canvas, crop empty space, or use the GIF compressor. The best choice depends on whether dimensions or colors cause most of the size.
