GIF Resizer
Make an animated GIF bigger or smaller by pixels, percent or preset — without dropping a single frame.
- Files never leave your device
- Same speed & frame count
- No watermark, no sign-up

Whole picture, new size
Resize Animated GIFs Without Breaking the Animation
A GIF resizer changes the size of the whole picture instead of cutting part of it away. Shrink a 1080-pixel screen recording so it fits in an email, scale a reaction GIF down for a chat app, or blow tiny pixel art up to a crisp 4×.
This GIF resizer works on every frame, keeps the timing and the loop, and never sends your file anywhere, because the resizing happens in your browser. The live preview shows the new proportions before you download.
How it works
How to Resize a GIF in 3 Steps
-
1. Upload the GIF you want to resize
Drop it into the GIF resizer above, choose it from your files, or paste it with Ctrl+V. Files up to 100 MB are fine.
-
2. Set the new size in pixels, percent or a preset
Type a width and the height follows when the ratio is locked, tap 50%, or choose a preset such as Email, 600 pixels wide.
-
3. Check the preview and download
Click Resize GIF, compare the original and new dimensions, and download the result. No watermark, no extra frames.
Three modes
Three Ways to Set the New Size
Pick whichever fits the job. Every mode in the GIF resizer gives you the same frame-perfect result.
By pixels, with the ratio lock
Type a width or a height and the GIF resizer calculates the other side, so nothing gets squashed. Switch the lock off only when you need an exact slot, such as 300 × 300.
By percentage
25%, 50% and 75% are one tap away, with 150% and 200% for enlarging. Percentages always keep the original proportions.
By preset size
128 × 128 emoji, 112 × 112 Twitch emotes, 256 × 256 avatars, and widths of 320, 600, 800 and 1280 pixels for thumbnails, emails, docs and HD.
Right tool, right job
Resize or Crop? Picking the Right Tool
Both change the dimensions of a GIF, but in very different ways, and choosing the wrong one is the most common reason a result looks off.
Resize when you want the whole picture, smaller
Use the GIF resizer when everything in the frame matters and it simply needs to take up fewer (or more) pixels. Nothing is removed; the entire animation is scaled evenly.
Crop when you only need part of the frame
To cut off borders, captions or empty space, crop instead. The GIF Cropper lets you drag any area or type exact pixel coordinates, and snaps to Discord, Slack, X and Instagram sizes.
Quality
How to Keep Quality When You Resize a GIF
Three things decide whether a resized GIF looks sharp or mushy.
Shrinking keeps detail; enlarging blurs it
Going smaller looks great, because several source pixels blend into each new one. Going bigger has to invent pixels that were never there, so a photo-style GIF enlarged by any GIF resizer turns soft. Start from the largest original you have.
Use 2×, 3× or 4× for pixel art
For pixel art and retro sprites, choose Pixel art resampling and a whole-number scale such as 200% or 300%. Every pixel becomes a clean square block with no blur; in-between scales like 150% make some blocks wider than others.
Premultiplied alpha keeps edges clean
Transparent pixels still carry a hidden color, often black or white. A basic resizer blends that color into the edges and leaves a halo. This GIF resizer weights each color by its opacity first, so only visible pixels count.
Why it's different
What You Get with This GIF Resizer
Runs entirely in your browser
The GIF resizer never uploads your file, so private GIFs stay private and there is no upload wait.
Same frames, same speed
Every frame keeps its own delay, so a three-second GIF is still three seconds long after resizing.
Loop setting kept as-is
Loops forever stays forever and plays once stays once. The GIF resizer copies the loop count exactly.
Up to 100 MB in, 4096 × 4096 out
Big recordings and long loops are welcome. The work runs in a background thread, so the page stays responsive.
No watermark, no login
Use the GIF resizer as often as you like: no account, no trial and no logo on your animation.
Smooth or pixel-perfect
Smooth (Lanczos) suits photos and video clips; Pixel art keeps sprites sharp and blocky.
FAQ
GIF Resizer FAQ
Quick answers about resizing animated GIFs. Didn't find yours? Email support@gifcropper.com.
Does resizing keep my GIF animated?
Yes. The GIF resizer processes every frame and keeps each frame's delay and the loop setting, so the resized GIF moves exactly like the original, just at a new size.
Will my GIF get blurry if I make it smaller?
No, making a GIF smaller generally keeps it sharp, because many pixels are blended into each new one with a high-quality filter. Blur comes from enlarging, not shrinking.
Is the resized GIF watermarked?
No. The download contains only your animation, with no logo, caption or extra frame added.
How big a GIF can I resize?
The GIF resizer accepts files up to 100 MB and can output up to 4096 × 4096 pixels. Because your own device does the work, very large GIFs may take several seconds.
Do I need an account to resize GIFs?
No. There is no sign-up and no email to give. Open the page, drop in a GIF and download the resized version.
Why is my resized GIF a larger file than the original?
Enlarging adds pixels, and smooth scaling creates new in-between colors that compress less efficiently. To keep the file small, resize down rather than up, choose fewer colors, or use Pixel art resampling for flat graphics.
Can I make a GIF bigger without it looking pixelated?
Smooth resampling avoids blocky pixels but adds some softness, and no tool can add detail that was never in the original. For pixel art, a whole-number scale with Pixel art resampling looks best.
