How to use the Resize GIF tool
- Drop a GIF into the box; its size and frame count appear.
- Enter a new width (height follows automatically) or unlock to stretch.
- Optionally lower the colors, drop frames, or enter a target size in MB.
- Press Resize GIF, check the preview and download.
Keep the animation
Many image tools only handle the first frame of a GIF, which turns your animation into a still picture. This tool decodes every frame, rebuilds each one at the new size, and writes a new animated GIF with the original timing. Frame delays are preserved, so the animation plays at the same speed.
Three ways to make a GIF smaller
File size depends on three things: dimensions, number of colors and number of frames. Shrinking the width has the biggest effect, since halving it cuts the pixels to a quarter. Reducing colors from 256 to 128 or 64 gives a further saving with little visible change for most clips. Keeping every second frame halves the data but makes motion slightly less smooth; the tool adds the dropped time to the remaining frames so the clip still lasts as long.
Hit a size limit
Chat apps, forums and streaming sites limit GIF uploads. Enter the limit in the target box, for example 8 MB, and the tool repeatedly lowers colors, size and, if needed, frames until the GIF fits. Very long GIFs may need a much smaller size to meet tight limits, and the tool tells you if it could not reach the target.
Stretch or keep the ratio
With the aspect ratio lock on, the height updates when you change the width so nothing looks squashed. Turn it off when a platform needs an exact box, such as a square emote, and you are happy for the animation to stretch slightly.
Quality notes
GIF can only show 256 colors per frame, so gradients may show banding, especially after reducing colors. Simple graphics, stickers and cartoons compress best; long video clips produce the largest files. For best quality, always start from the original GIF rather than one that was already compressed.
Runs on your device
Decoding and encoding happen in your browser, so even large GIFs are never uploaded. Long or high-resolution GIFs can take several seconds on phones.
Ideal sizes
For chats, 480 pixels wide is usually plenty; for emoji, 128 pixels.
Frequently asked questions
Does resizing keep the GIF animated?
Yes, every frame is resized and the timing is kept.
How do I reduce GIF file size?
Lower the width, reduce colors, drop frames, or enter a target size in MB.
Can I make a GIF a specific size in MB?
Yes, type the size into the target box and the tool works towards it.
Is there a file size limit?
No fixed limit, but very large GIFs need plenty of device memory.
Are my GIFs uploaded?
No, everything runs in your browser.
