How to Compress a GIF

How to compress a GIF online (step by step)

The fastest way to compress a GIF is in the browser. GIF Compressor decodes every frame, keeps only the pixels that change, builds a better palette and re-encodes with a lossy LZW encoder in one pass. Your files stay on your device.

1. Add your GIFs. Drag files or a folder onto the drop zone, click Select files, or paste with Ctrl/⌘+V.
2. Let it compress. It starts automatically at Balanced (lossy 30, 256 colors). Each file shows its new size, frame count and saving.
3. Check the animation. Click Preview to watch the original and the result play side by side.
4. Adjust if needed. Pick Smallest, High quality or Lossless. Under Advanced options you can drop every Nth frame, change speed, resize, or set a target size.
5. Download. One GIF downloads directly; several come as one ZIP.

Which method shrinks a GIF the most?

We ran one file through each method we could measure: video-clip.gif, 480×270, 60 frames, 3.32 MB.

Two lessons. Re-encoding alone can make a GIF bigger: ffmpeg’s palette pass grew this clip by 3% and a photo animation by 30% (555 KB → 721 KB), because dither noise breaks LZW’s patterns. Lossless helps only unoptimized GIFs: it saved 85% on a raw screen recording but 0–1% on video-derived ones.

How the tools compare on features:

How to reduce GIF file size: the 5 levers

Every method above pulls some mix of these levers. Use them in this order: the first ones cost the least quality.

1. Store only what changes between frames

GIF frames can be partial: a frame may hold just the rectangle that changed, with unchanged pixels marked transparent. Many exporters save every frame in full. Rebuilding the frames this way is lossless, and it’s why our screen recording went from 484 KB to 70 KB with identical pixels.

2. Use lossy LZW compression

GIF’s LZW compression is lossless, but an encoder may swap a pixel for a near-identical color when that extends a pattern. On video-like GIFs this is the biggest single lever: Balanced cut the clip above by 62% at the same size and frame count.

3. Reduce colors and turn off dithering

GIF allows up to 256 colors per frame. Fewer colors means shorter codes and longer runs. Dithering hides banding but adds noise that costs bytes, so leave it off unless gradients band.

4. Drop frames

To downsize a GIF without shortening it, remove every 2nd frame and add its delay to the previous frame, so the GIF plays for the same length of time. A 30 fps clip at 15 fps still looks smooth for most content.

5. Shrink the dimensions

Halving width and height leaves a quarter of the pixels in every frame. It’s the strongest lever but the most visible, so use it last, or when the GIF is shown smaller than it’s stored anyway.

How to compress a GIF in Photoshop

1. Open the GIF. To remove frames, delete them in Window → Timeline, then raise the remaining frames’ delay.
2. Image → Image Size to set a smaller width.
3. File → Export → Save for Web (Legacy) (Alt+Shift+Ctrl+S / Option+Shift+Cmd+S), and choose GIF.
4. Lower Colors (try 128, then 64), set Dither to No Dither, and raise Lossy. Adobe says 5–10, sometimes up to 50, usually won’t degrade the image.
5. Watch the size readout in the lower-left corner, or use the panel menu’s Optimize to File Size. Then save.

How to compress a GIF on Mac

The quickest way is any browser tool: open the GIF compressor in Safari or Chrome and drop the file in. With built-in apps, Preview can only resize. Choose View → Thumbnails, press ⌘A to select every frame, then Tools → Adjust Size, enter a smaller width and save. Preview has no color or lossy settings, and users report the saved GIF can stop looping. Check it before you share it.

How to compress a GIF in Canva

Canva has no compression setting for GIFs. Its “Limit file size” option only works for PNG and JPG. To get a smaller GIF from Canva:

1. Make the design smaller (a smaller custom size) and shorter, with fewer animated elements.
2. Share → Download, choose GIF. Free accounts export up to 1280×720 and 1 minute.
3. Compress the downloaded file in a GIF compressor to get the real savings.

How to compress GIFs with ffmpeg or gifsicle

Developers can script it. These are the ffmpeg commands we measured above (ffmpeg 7.1):

# Half size, 128-color palette, Bayer dither, only changed rectangles (−80% on our clip)
ffmpeg -i in.gif -vf "scale=iw/2:-1:flags=lanczos,split[a][b];[a]palettegen=max_colors=128:stats_mode=diff[p];[b][p]paletteuse=dither=bayer:bayer_scale=3:diff_mode=rectangle" out.gif

# gifsicle: frame optimization + lossy LZW + 128 colors (flags from the gifsicle manual)
gifsicle -O3 --lossy=80 --colors 128 in.gif -o out.gif

Compare the output size before you replace anything. As the table shows, a re-encode can grow a GIF that was already optimized.

How to compress a GIF for Discord

Discord’s free upload limit is 20 MB (up from 10 MB in August 2026, per Discord’s support page), and Nitro Basic is 50 MB. Custom emoji must be under 256 KB, and stickers under 512 KB at 320×320. Most GIFs already fit the 20 MB upload limit: Balanced alone took our 14.57 MB, 150-frame test GIF to 7.1 MB. For emoji, use the 256 KB preset; a 978 KB GIF came out at 252 KB. The compress GIF for Discord page has all three presets ready.

Why won't my GIF get smaller?

• It’s already optimized. Lossless can’t beat an optimized encoder; our video clips moved 0–1%. Use lossy, fewer frames or a smaller size.
• Every pixel changes every frame. Camera motion and fades defeat frame differencing. Drop frames or resize.
• It’s dithered. Noise patterns resist LZW. Turn dithering off or lower lossy noise.
• You’re re-compressing a compressed copy. Each lossy pass adds artifacts. Start from the original.
• It’s tiny. Our 2 KB test GIF only saved 0.5 KB, because headers and palette dominate.
