Exact pixels
Enter a specific width, height, or both for a website slot, chat sticker, email, presentation, or upload limit. Leave one dimension empty and GIFClear calculates it from the original aspect ratio.

How to Resize a GIF
Add your animated image
Drag in a GIF, choose one from your device, or paste an image with ⌘V or Ctrl+V. GIFClear reads the dimensions locally and does not upload the file.
Choose the new size and fit
Enter width and height in pixels, scale by a percentage, or select an integer multiple. Keep the aspect ratio locked for natural proportions, or choose crop, stretch, original ratio, or transparent padding for an exact output canvas.
Preview and download
Click Resize GIF while the Web Worker processes every frame. Compare the original and resized animations, check the dimensions and file sizes, then download the GIF with its new dimensions in the filename.
Choose Your Size: Pixels, Percentage or Multiples
Percentage
Use 50% to make both dimensions half size or 150% for a one-and-a-half-times enlargement. Percentage scaling keeps the source proportions and is useful when you know the relative change you need.
2x, 3x, or 4x
Integer multiples are a predictable choice for pixel art, icons, and small animations. They cannot add new detail, but often keep repeated pixel edges more consistent than a fractional enlargement.
What Happens When the Aspect Ratio Doesn't Match
An 800 × 600 source and a 500 × 500 target have different shapes. Center and crop fills the square and removes equal areas from opposite edges. Stretch to fit keeps the exact canvas but changes the shape of the content.
Force original aspect ratio changes the requested box to the closest proportional dimensions, so nothing is cropped or distorted. Add transparent padding keeps the complete image centered inside the requested canvas and fills the unused area with transparency.
Resizing Up vs Down — What Stays Sharp
Scaling down combines source pixels, so the result usually looks clean at its new display size and may use fewer bytes. Small text and one-pixel lines can soften or disappear, so always inspect a full loop.
Scaling up creates more pixels but not more original detail. Photos and gradients may look soft, and GIF's limited palette can make color bands more visible. Start from the largest original available, keep the aspect ratio locked, and prefer 2x, 3x, or 4x for pixel-style artwork.
How to Fix Flickering or Missing Parts
Most GIFs resize correctly with this option off. If your resized GIF flickers, leaves trails behind moving objects, or has missing parts, turn on Fix flickering or missing parts and resize again.
This option can help with these display problems, but processing may take longer. Preview the animation before downloading to check whether it helped.
Frequently Asked Questions
Clear answers about GIF dimensions, quality, blur, animation timing, browser limits, and private local processing.
How do I resize a GIF?
Choose, drop, or paste an animated GIF, then enter a width and height, choose a percentage, or select 2x, 3x, or 4x. Pick how mismatched proportions should be handled, click Resize GIF, preview the full animation, and download the result. The work happens locally in your browser.
Can I resize a GIF without losing quality?
Reducing a GIF usually keeps edges clean, but every GIF export is limited to a 256-color palette per frame and must be re-encoded. Enlarging cannot create detail that is missing from the source. Use the original aspect ratio, prefer integer enlargement such as 2x, and compare text, edges, gradients, and transparency before downloading.
Why does my resized GIF look blurry?
A GIF can look blurry when it is enlarged beyond its original dimensions, stretched to a different aspect ratio, or displayed by another app at a non-native size. Try 2x, 3x, or 4x instead of an uneven enlargement, keep the aspect ratio locked, and avoid Stretch to fit unless you need exact dimensions.
Does the animation still work after resizing?
Yes. GIFClear processes every frame and exports another animated GIF. For GIF sources it preserves the original frame delays and loop count. Preview a complete loop before downloading because some viewers impose their own minimum delay for very fast frames.
What is the maximum size for an animated GIF?
GIFClear allows output dimensions up to 8192 pixels per side, but the practical limit depends on frame count, source dimensions, and available browser memory. Outputs above 1920 pixels trigger a warning. Large animations are usually more reliable on a desktop browser, and resizing them down before compression can substantially reduce memory and file size.
Are my GIF files uploaded to a server?
No. GIFClear reads, decodes, resizes, previews, and re-encodes your animation locally in your browser. Your source file and resized result are never uploaded to a processing server. Keep the tab open until the local Web Worker finishes.
Need a smaller file after resizing? Try the GIF Compressor. Starting from a video or frames? Use the GIF Frame Extractor to inspect or save the animation sequence.
