About GIF Compressor

The GIF Compressor shrinks an animated GIF until it fits the size limit you choose: 10 MB for a Discord upload, 256 KB for a Discord emoji, 1 MB for a Twitch emote, 128 KB for a Slack emoji or 5 MB for an email. Pick the limit, press one button, and it hands back the best-looking GIF that fits, with the animation, timing and transparency kept. Your file stays on your device the whole time.

At a Glance

GIF Compressor shrinks an animated GIF under the size limit you pick, such as 10 MB for Discord or 256 KB for an emoji, and keeps the best-looking version that fits, with the animation, timing and transparency kept.

How to compress a GIF to a target size

Add your GIF: drag a .gif onto the drop area or tap Choose a GIF File. Nothing is uploaded.
See what makes it heavy: the report shows the frames, length, colours and how much of each frame repeats the one before it.
Pick a target: tap a preset such as Discord upload or Slack emoji, or type your own limit in KB or MB.
Press Compress to target: the tool tries real versions of your GIF and keeps the best-looking one under the limit.
Compare and download: the original and the result play side by side. Adjust by hand if you like, then press Download GIF.

Size limits worth knowing

Where it goes	Typical limit	What usually works
Discord upload (free account)	10 MB	Full size is often fine after the lossless pass; drop to 480 px wide if not
Discord custom emoji	256 KB	128 × 128, 64 colours, 12–15 fps, a short loop
Twitch animated emote	1 MB	112 × 112, at most 60 frames
Slack custom emoji	128 KB	128 × 128, 32–64 colours, 8–12 fps
Email attachment	≈ 5 MB safe	Many mail servers refuse large files long before 25 MB
GitHub README or web page	≈ 2 MB	640 px wide, 10–12 fps, 128 colours

The presets use these values. Platforms change their limits from time to time, so if yours is different, type it into the custom box and the tool works to that number.

What makes a GIF smaller, from free to costly

Change	How much smaller	What you give up
Lossless pass: store only the part of each frame that changes	Often 20–60% when the background stays still	Nothing
Narrower width	Half the width is about a quarter of the size	Fine detail; usually the least visible trade
Fewer frames per second	24 → 12 fps roughly halves it	Smoothness; fine for screen recordings, harsh on fast action
Fewer colours	256 → 64 colours saves 15–30%	Banding on gradients and skin; invisible on cartoons and screenshots
Dithering off	5–20%	Flatter gradients, crisper flat art

Compress to target goes down this list in order, so a GIF that fits after the lossless pass keeps every pixel, and quality is only traded when the limit demands it.

Why a GIF is so much bigger than the video it came from

GIF is a format from 1987. It stores each frame as a picture with up to 256 colours and cannot describe motion the way MP4 does, so the same clip is often ten to twenty times larger as a GIF. Its one saving trick is letting a frame redraw only a rectangle and keep the rest of the previous frame, and many apps that export GIFs do not use it. That is why a GIF made by a phone or a screen recorder can often shrink a lot with no visible change, while a long, busy clip of real footage has a floor it cannot go below while staying watchable.

Frequently Asked Questions

How do I get a GIF under the 10 MB Discord limit?

Drop the GIF in, tap the Discord upload preset and press Compress to target. If the lossless pass is enough, the tool stops there and nothing changes in the picture. If not, it narrows the width, trims colours or drops frames, step by step, and keeps the best-looking version under 10 MB. Nitro raises the limit, so type your own target if yours is higher.

How do I make an animated Discord emoji under 256 KB?

Tap the Discord emoji preset. It targets 256 KB, and the tool usually lands on about 128 pixels wide with fewer colours and frames, which is the size Discord shows emoji at anyway. For a sticker or a Slack emoji, pick those presets or type the limit.

Will compressing my GIF make it blurry?

Not necessarily. The first pass is lossless: each frame keeps only the part that changed and the colour table is rebuilt from the colours the file really uses. Many GIFs shrink by 20 to 60 percent from that alone. Quality is only reduced when the limit demands it, and the page tells you how close the result looks to the original.

Why is my GIF still too big after compressing?

A long, busy or full-screen clip has a limit below which it stops being watchable as a GIF. If even the smallest version misses your target, the fixes are a shorter clip, a smaller frame, fewer frames per second, or sending it as an MP4 instead, which is far smaller for real footage.

Does it keep the animation, timing and transparency?

Yes. Every frame keeps its own delay, the loop setting is kept, and transparent areas stay transparent. When frames are dropped to save space, their time is given to the frame before them, so the animation still lasts the same number of seconds instead of speeding up.

Can I compress a GIF on my phone?

Yes. The page works in mobile Safari and Chrome. Tap Choose a GIF File to pick one from your photos or files, and the compressed GIF downloads to your phone. Very large GIFs take longer on a phone than on a computer.

Is my GIF uploaded to a server?

No. Every step runs in your browser on your own device, so the file never leaves it. Nothing is stored and no account is needed.
