Most image tools resize a GIF by quietly taking its first frame, and hand back a still picture. This one resizes every frame and puts the animation together again, with the timing and the loop as they were. Type a width, a height or a percentage and the whole clip is scaled.
Resizing is also the most effective way to make a GIF lighter. File size follows the number of pixels in each frame, so going from 800 to 400 pixels wide removes three quarters of the data before a single colour has been touched. This page opens with the Resize panel on and the format kept as GIF.
One rule decides whether the animation survives: the frames may be scaled, and nothing more. Keep the fit on Keep ratio or Stretch to size. Fill and crop and Fit and pad change the shape of the frame, and those work on one frame only. Your GIF travels over an encrypted connection, is resized on our own servers and is removed within one hour.
Picking a size for where the GIF will be shown
A GIF is almost never viewed full screen. In a chat it appears in a bubble 300 to 400 pixels wide. In a document or a help article, 600 to 800 pixels covers a column of text. In an email, 600 is the usual width of the whole layout. On a slide, 800 to 1000 is ample. Anything larger than its slot is scaled down by the program that shows it, after the viewer has already downloaded every unused pixel.
So measure the slot and resize to that, or to double it if sharpness on high-density screens matters more to you than weight.
Why scaling down can look rough, and what helps
Each frame of a GIF has its own small palette, and fine patterns in the original are often made of dots of two colours placed side by side to fake a third. When frames are scaled, those dots are averaged into new in-between colours, and the result has to be squeezed back into 256. On photographic clips you may see slightly coarser shading than before.
Two habits help. Resize in one step from the original, never from a GIF that has already been reduced once. And choose simple ratios where you can: exactly half or exactly a quarter keeps thin lines and text cleaner than an odd factor such as 0.63.
Enlarging a GIF
Images are not enlarged unless you switch on Allow enlarging, and for GIFs there are two reasons to think first. The file grows with the square of the scale, so doubling a 3 MB GIF gives roughly 12 MB. And the detail that was never recorded does not appear: a small, soft clip becomes a large, soft clip. Pixel art is the exception worth knowing, since its hard squares scale up cleanly at whole multiples. The AI upscaler on this site works on still pictures only.
Frequently asked questions
Will my GIF still be animated after resizing?
Yes, as long as you only change the size with the fit on Keep ratio or Stretch. All frames, their delays and the loop setting are kept.
Can I crop a GIF to a square and keep it moving?
Not at present. Cropping, and the Fill and crop fit, return the first frame as a still picture, with a warning. Scale the whole frame instead.
How much smaller does the file get?
Roughly in proportion to the pixels. Half the width and height gives about a quarter of the size; 70 percent gives about half.
Does resizing change the speed of the animation?
No. The delay stored for each frame is carried over unchanged, so the clip plays at the same pace.
Can I save the resized animation as WebP?
Yes. Pick WebP in the Format menu. The animation is kept and the file is usually less than half the size of the GIF.
Is there a limit on the GIF I can resize?
Up to 300 frames, in a file of up to 20 MB on the free plan or 200 MB on Pro.
