GIF Resizer
Resize animated GIFs and WebP animations without losing a single frame using our GIF Resizer. Enter a width, a height or both, choose whether to fit inside the box, crop to cover it or stretch to fill it, and every frame is scaled with high quality Lanczos resampling while the original frame delays and loop count stay intact. Perfect for chat apps, forums, emails and websites.
Frequently asked questions
How do I resize an animated GIF?
Upload a GIF or animated WebP, enter the new width, height or both, and choose a fit mode. Every frame is scaled to the new size and the result is saved in the same format as the upload.
What happens if I enter only the width or the height?
The other side is calculated from the original aspect ratio, so the animation is never distorted. For example, a 480 by 270 GIF resized to a width of 240 becomes 240 by 135 pixels.
What do the fit modes do?
Inside, the default, scales the animation to fit within the width and height while keeping its proportions. Cover fills the whole box and crops the overflow from the center, and fill stretches the frames to exactly the given size. The fit mode only matters when you enter both a width and a height.
Are frame delays and looping kept?
Yes. Every frame keeps its original delay, the loop count stays the same, and no frames are dropped or merged, so the resized animation plays exactly like the original.
Can I make a GIF bigger?
Yes, you can enlarge an animation up to 2000 pixels per side, as long as all frames together stay under 16 megapixels. Enlarging cannot add detail, so pixel art may look soft; resizing by whole multiples gives the cleanest result.
What are the limits?
Uploads can be up to 5 MB with up to 300 frames. The input and the result can each be up to 2000 pixels per side and 16 megapixels across all frames.
Does resizing change the colors?
Scaling blends neighboring pixels, so the GIF palette is computed again for every frame with up to 256 colors. Animated WebP results are saved as lossy WebP at quality 90, which keeps them very close to the original.
Is transparency preserved?
Yes, transparent areas stay transparent. In GIF output, edges that become semi-transparent while scaling are stored as either solid or clear, because GIF has no partial transparency.
Will resizing make my GIF smaller in bytes?
Usually yes, because file size grows with the number of pixels. Halving the width and height leaves a quarter of the pixels, which typically cuts the file size by more than half. For further savings, run the result through the GIF Compressor.
Which formats can I upload?
GIF and WebP files are accepted, animated or still. Other formats are rejected; to resize a still JPEG or PNG, use the Image Resize tool.
