How to Resize Animated GIFs Online
Animated GIFs often need resizing to meet platform requirements. Discord emoji must be 128x128, Telegram stickers 512x512, and web publishers need GIFs that do not slow down page loading. Pixotter resizes every frame of your animated GIF while preserving timing, transparency, and loop behavior.
All processing happens in your browser. Your GIF is never uploaded to a server. This means resizing is instant, private, and free with no signup or watermarks.
Resize by Pixels or Percentage
Enter exact pixel dimensions for platform-specific requirements, or use the percentage slider for proportional scaling. The aspect ratio lock ensures your GIF does not get stretched or squished. Unlock it if you need to change the proportions deliberately.
Platform Presets
One click sets the right dimensions for Discord emoji (128x128), Discord banners (960x540), Slack custom emoji (128x128), Telegram stickers (512x512), and Twitter (480x480). After resizing, add a compress step to further reduce file size if you need to meet upload limits.
Pixotter is built for pipeline processing. Resize, compress, and convert your GIF in a single pass without re-uploading between steps. Every operation chains in browser memory for maximum speed and convenience.
Frequently Asked Questions
Can I resize a GIF without losing animation?
Yes. Pixotter resizes every frame of the animated GIF individually, preserving frame timing, loop count, and transparency. The animation plays exactly as before, just at the new dimensions.
How do I resize a GIF for Discord emoji?
Click the "Discord Emoji (128x128)" preset. Discord requires custom emoji to be 128x128 pixels or smaller and under 256KB. After resizing, you may want to add a compress step to hit the file size limit.
What happens to GIF quality when resizing?
Scaling down preserves quality well because you are discarding pixels. Scaling up can cause blurriness since the resizer must interpolate new pixels. For best results, try to stay at or below the original dimensions.
Can I resize by percentage instead of pixels?
Yes. Use the scale percentage slider to resize proportionally. Setting it to 50% halves both width and height, reducing the total pixel count by 75% and significantly cutting file size.
Does resizing reduce file size?
Yes. A GIF stores pixel data for every frame, so reducing dimensions has a multiplicative effect on file size. Halving both dimensions typically reduces file size by 60-75%. For even more savings, chain resize with compress.
Can I make a GIF larger?
You can scale up to 200% of the original, but upscaling an animated GIF produces blurry frames since new pixels are interpolated. For the best quality, start with the highest resolution source you have.
