GIF tool
Reduce GIF file size
Shrink animated GIFs for chat apps, email, and sites that bounce oversized loops. Cap the longest edge, dial colors, or chase a KB target—then download a lighter copy.

How it works
- 01
Drop your GIF
One loop or several. A first-frame thumbnail appears so you can tell stickers and memes apart before you press Reduce.
- 02
Cap size, colors, or KB
Use Options to shrink the longest edge, lower palette quality, or chase a hard KB target for chat and email limits.
- 03
Check, then download
Compare first frames if detail matters, confirm the new size, then download one file or a ZIP of the batch.
When an animated GIF is “too heavy”
GIFs store every frame as indexed colors. A short reaction clip exported from a phone screen recording can still weigh megabytes because width, frame count, and a busy palette stack on top of each other. Chat apps and ticket systems often silently reject the upload or refuse to play it.
This tool re-encodes the loop in your browser: optional resize, fewer colors, and—when you set a KB aim—thinner frame sampling. You see the new size in the list before you download.
What shrinks well (and what doesn’t)
Large stickers, banners, and screen captures
Wide loops with hundreds of frames respond best to a max-edge cap (480px or 360px is often enough for chat). Dropping palette colors next usually saves more weight than nudging quality alone.
Tiny, already-optimized memes
A 200×200 sticker with 32 colors may already be near the floor. Forcing “more compression” can make the file larger after re-encoding. When that would happen, we keep your original and label it—same honesty rule as our PDF tool.
How to use the Options panel
- Resize longest side — the strongest lever for banner GIFs. Leave it off for stickers that must stay pixel-sharp at their current size.
- Colors / quality — maps to palette size. Lower for chat; raise when faces or logos look posterized.
- Aim for a max file size — turn on when email or a CMS prints a number. We’ll also thin frames slightly while chasing the cap.
Practical tips before you send
- Trim the clip in your editor first if half the frames are a static hold— fewer frames beat aggressive recoloring.
- Prefer 480px or smaller for Slack/Discord stickers unless the team needs a full-width banner.
- After changing Options, press Re-run so the new cap actually applies.
- Always open Compare once—Play both / Pause both checks whether the reduced loop still feels smooth next to the original. List thumbnails stay still on purpose.

Common questions
How does GIF compression work here?
We decode every frame, optionally shrink the longest edge, thin frames when you’re chasing a KB target, and re-encode with fewer palette colors. If the result wouldn’t beat the original size, we keep your GIF and say so.
Will my animation still play after reducing?
Yes—you still get an animated GIF. Open Compare to play original and reduced side by side (Pause both freezes on stills). List thumbnails stay on the first frame to keep the queue light.
Will transparent sticker GIFs stay transparent?
Yes. We keep GIF 1-bit transparency when the original has a clear background, so reduced stickers shouldn’t turn into a black box. Soft edges may look a bit harder because GIF only supports on/off transparency.
Why won’t this sticker GIF get smaller?
Short loops with few colors and a small canvas are often already tight. Try a smaller max edge or lower the colors/quality slider. Tiny targets on already-compact stickers may not be reachable without looking broken.
Can I hit a max size like 500 KB?
Turn on “Aim for a max file size,” enter your KB limit, and press Reduce. We’ll shrink edges, colors, and frame density when needed. Some long, colorful clips simply can’t land under a harsh cap and stay watchable.
Can I reduce several GIFs at once?
Yes. Add a batch, reduce together, then download individually or as a ZIP. Re-run one file after tweaking Options without redoing the whole queue.
