This page resizes GIF files specifically. The GIF format is decoded, scaled and re-encoded entirely inside your browser, so the file never travels anywhere and the output stays in GIF.
How it works
- Select one or more GIF files.
- Enter the width or height you want, in pixels or as a percentage.
- Keep the aspect ratio locked unless you specifically need to distort the image.
- Download the result as GIF.
Good to know
Resizing a GIF file re-encodes it, which means the compression is applied again. Going down in size usually shrinks the file considerably; going up will make it larger without adding real detail.
Frequently asked questions
Does resizing GIF lose quality?
Scaling down looks clean because you are discarding pixels you no longer need. Scaling up cannot add information, so a GIF enlarged well beyond its original size will look soft.
Can I resize several GIF files at once?
Yes — select as many GIF files as you like and the same dimensions are applied to all of them.
