What is the Discord GIF size limit?

8MB for standard users, 50MB for Nitro subscribers. Server emoji GIFs are limited to 256KB. Server profile GIFs (animated avatars) are Nitro-only. For chat GIFs, 8MB is the limit — anything larger shows as a file download instead of playing inline.

What is the Slack GIF size limit?

Slack does not have a strict upload limit, but GIFs over 5MB may not play inline — they show as file attachments instead. For smooth inline playback, keep GIFs under 5MB. For Slack emoji, the limit is 128KB and 128x128 pixels maximum.

How do I compress a GIF for Discord under 8MB?

Upload your GIF to the compressor. Start with: 128 colors, 15fps, and width of 480px. Check the output size. If still over 8MB: drop to 64 colors, 10fps, or 320px width. A 3-5 second GIF at 480px/128 colors/15fps is typically 2-4MB — well under the limit.

Can I use a compressed GIF as a Discord emoji?

Discord emoji must be under 256KB and 128x128 pixels. This is very restrictive. Reduce to 128x128px, 32-64 colors, and 10fps. Keep the animation short (1-2 seconds max). Even then, some GIFs cannot hit 256KB — convert to a static PNG if the animation is not essential.

How do I compress a GIF for email?

Most email providers limit attachments to 25MB (Gmail, Outlook). But large GIFs slow down email loading. Aim for under 2MB for email GIFs. Reduce to 480px width, 128 colors, 15fps. If embedding in an HTML email, smaller is better — many email clients block GIFs over 1MB from auto-playing.

Why does my GIF not play inline on Discord/Slack?

File size. If the GIF exceeds the platform limit (8MB Discord, ~5MB Slack), it is treated as a file attachment and shows a download link instead of playing inline. Compress below the limit and it will auto-play in the chat.

Step-by-Step: Compress for Discord

Upload your GIF — drag and drop into the compressor

Still too large? Reduce to 10fps or 320px width

Discord Emoji (256KB Challenge)

Animated Discord emoji are the hardest — 256KB is extremely small for a GIF. Tips:

128x128px maximum — resize first
32 colors — aggressive but necessary at this size
10fps or lower — reduce frames
1-2 seconds max — every frame costs KB
Simple animation — minimal motion, solid backgrounds compress better
If still over 256KB: shorten the animation or convert to static PNG
