Online GIF Compressor
Use this online GIF compressor to reduce GIF size for chat uploads, Slack emoji, email, websites, or a custom target. The tool outputs GIF files and runs locally in your browser, so there is no upload to us.
Pick an upload target
We'll fit your GIF under this limit while keeping it as close to original as possible.
Targets that match real limits
Pick a Discord, Slack emoji, email, web, or custom target instead of guessing compression settings.
Local browser compression
The GIF is processed in your browser with WebAssembly, then you download the compressed .gif result.
Output stays GIF
The tool compresses animated GIF files directly, without converting them to WebP or another format.
Three steps. Zero uploads.
The entire pipeline runs in your browser tab.
Upload
Drop a GIF into the tool or choose one from your device.
Choose a target
Select a preset or enter a custom size target before compression starts.
Download
Preview the result, check whether the target was reached, and download the compressed GIF.
Common questions
Does this upload my GIF?+−
No. The compression flow is designed to run locally in your browser.
Which GIF targets are included?+−
The tool includes Discord Free 10MB, Discord Safe 8MB, Slack Emoji 128KB, Email Safe 20MB, Web 5MB, and custom targets.
Where should I start for Discord or Slack?+−
Use the [GIF Compressor for Discord](/compress-gif-for-discord) for Discord upload targets, the [GIF Compressor for Slack](/slack-emoji-gif) for Slack emoji files, or [How to Make a Slack Emoji GIF](/how-to-make-slack-emoji-gif) when you need the full Slack upload workflow.
Will it always hit the target size?+−
Not always. Some GIFs need fewer frames, smaller dimensions, or fewer colors before they can fit a strict target. See [How to Reduce GIF Size](/how-to-reduce-gif-size) for the step-by-step trade-offs.
