GIF Compressor — Hit an Exact File Size
Aim for a number — 8MB, 2MB, 500KB — and watch it land under your target before you download.
Need a GIF compressor that lands on a specific number instead of guessing? This one targets an exact file size — set 8MB for Discord, a few hundred KB for an email attachment — and a before/after preview shows the result before you download. Below: the three-step flow, how the lossy compression works, which levers (palette, dithering, frame rate) shrink a GIF most, and the questions people ask about reducing animated GIF size.

How to compress a GIF to a target size
- 1
Drop your GIF into the compressor
Drag an animated GIF onto the drop zone, or click to browse. It loads straight into the browser through WebAssembly — nothing is uploaded to a server, so there's no upload limit to fight.
- 2
Set your target size and dial in
Type the MB or KB cap you need and run it. The lossy palette, color reduction, and frame rate step down together automatically until the GIF lands under your target, and the final file size is shown before you download.
- 3
Download the smaller GIF
Once the preview meets your target, click to save. The compressed GIF lands on your device clean and unbranded — no watermark, no signup, no queue.
Why GIFMaker
Compress to an exact MB or KB target
Most tools give you a vague quality percentage; this one works backward from a number. Set 8MB, 2MB, or 500KB and the encoder reduces palette and frame rate until the GIF fits under that cap.
In-browser WebAssembly, no upload limit
FFmpeg compiled to WebAssembly runs the compression on your own machine, so the GIF never leaves your device and a 60MB source isn't blocked by some site's upload limit.
Exact final size, shown before download
After compression the exact output size is shown next to your target — in MB or KB — so you confirm the GIF landed under the number before you download it.
Clean output, no watermark
The compressed GIF downloads unbranded, with no watermark, logo, or account gate stamped onto it. What you get back is the same animation, just lighter.
How do you make a GIF file size smaller?
Shrink a GIF by cutting three things at once: trim the palette so fewer colors are stored per pixel, drop the frame rate so the file holds fewer frames per second, and apply lossy compression that lets near-identical frames share data. Together these can cut a GIF by 50–80% with little visible quality loss.
The compressor moves all three levers from a single target, so you set the MB or KB you want and it balances them for you. If you'd rather tune one knob at a time — a smaller palette, fewer frames, or a tighter dither pattern — optimize the GIF gives you that manual control instead. Both run on the same in-browser GIF toolkit, so nothing uploads either way.
How small can you compress a GIF for Discord, Slack, or email?
Aim for whichever platform cap you're sending to and set the compressor a hair under it: Discord allows 8MB on free accounts, Slack and most email attachments start rejecting files around 5–25MB, so picking a target safely below that ceiling keeps the upload from bouncing back at you. A short reaction GIF usually drops under 8MB with room to spare once you reduce the palette and frame rate.
If you're posting specifically to one chat app, the Discord GIF optimizer pre-loads the 8MB target for you. And when the GIF is too big mostly because it's too wide, resize the GIF to fewer pixels first — a narrower frame gives the compressor less data to chew through, so size and dimensions drop together.
Does compressing a GIF lose quality?
Compression trades some fidelity for size, but a well-built palette hides most of it: GIF is already capped at 256 colors, so color reduction and dithering scatter the loss across pixels instead of banding it, and trimming frame rate removes redundant frames the eye barely tracks. The result usually looks clean at a fraction of the megabytes.
GIF has no truly lossless path to a smaller file — every real size cut is lossy — so the goal is hitting your target with the least visible damage. If quality matters more than format, converting the source with video to GIF and a smart palette often beats compressing a bloated GIF after the fact.
