Make GIFs for Discord, WhatsApp, Slack & More — Size Limits and Settings Cheat Sheet

Platform Limits — The Complete Reference

Every platform handles GIFs differently. Some auto-compress, some reject oversized files silently, and some convert GIFs to video behind the scenes. Here is what actually works on each platform:

Platform	GIF Limit	Auto-Converts?	Recommended Settings
Discord (free)	8MB	No	480px, 12fps, <6 sec → ~2-4MB
Discord (Nitro)	50MB	No	640px, 15fps, generous duration
WhatsApp	No official GIF upload	Converts to short MP4	Send as short video (<6 sec) or use GIPHY search
Slack	No hard limit	Auto-compresses large GIFs	480px, 12fps, keep under 5MB for speed
Twitter/X	15MB	Converts to MP4 on display	480-640px, 15fps, <10 sec
Reddit	20MB	Large GIFs → video player	480px, 15fps — Reddit compresses anyway
Telegram	No limit (auto-converts)	Always converts to MPEG4	Keep under 5MB for mobile users
GitHub README	10MB	No	640px, 15fps, 5-8 sec for demos
Email (Gmail)	25MB total	No	320px, 10fps, <3 sec — keep GIFs under 1-2MB
iMessage	No limit	No	480px — recipient pays data costs
Jira/Confluence	10MB default	No	640px, 12fps — useful for bug report demos

Discord — The Most Common Use Case

Discord is where most GIFs are shared, and the 8MB free limit is the tightest constraint people hit. Here is the reliable workflow:

1. Open the Video to GIF tool
2. Drop your video clip
3. Set width to 480px and frame rate to 12fps
4. Trim to under 6 seconds
5. Convert — result is typically 2-4MB

If the GIF is still over 8MB: Run it through the GIF Compressor for another 30-40% reduction. Or reduce to 320px wide — smaller canvas, smaller file, still looks great in Discord's chat window.

Pro tip: Discord displays GIFs at about 400px wide in desktop chat. A 480px GIF is slightly larger than the display size, so it stays sharp. Going to 640px or 1080px just wastes file size — Discord will scale it down anyway.

WhatsApp — It Is Complicated

WhatsApp does not support uploading GIF files directly. When you "send a GIF" on WhatsApp, you are actually sending a short, muted MP4 video that auto-loops. This means:

• Using GIPHY search (built into WhatsApp) — works, but limited to what GIPHY has indexed
• Sending a GIF file — WhatsApp converts it to a short video. Quality degrades in the conversion. Files over 5MB may fail silently.
• Better approach: Instead of converting video → GIF → WhatsApp video, just trim your video to under 6 seconds and send it directly. Skip the GIF step entirely — same visual result, better quality, smaller file.

If you specifically need a GIF for WhatsApp (not a short video), keep it under 3MB and under 5 seconds. WhatsApp's auto-conversion works best with small, short GIFs.

Social Media — GIF vs Short Video

For TikTok, Instagram Reels, and YouTube Shorts, GIF is the wrong format. These platforms want video.

Platform	Format to Use	Tool
TikTok	MP4 (9:16, <60 sec)	Crop to 9:16 + Speed up if needed
Instagram Reels	MP4 (9:16, <90 sec)	Crop to 9:16 + Compress
Instagram Story	MP4 (9:16, <15 sec)	Trim to 15 sec + crop 9:16
Twitter/X post	GIF (<15MB) or MP4	Video to GIF (Twitter converts to MP4 anyway)
LinkedIn	MP4 only (no GIF support)	Convert + Compress

The rule: If the platform supports video natively, send video. GIF is only better for messaging apps (Discord, Slack, email) where auto-play and no-click simplicity matter.

Quick-Reference Workflow by Platform

Start with your video clip and follow the workflow for your target platform:

• Discord: Video to GIF (480px, 12fps, <6 sec) → Compress GIF if over 8MB
• Slack: Video to GIF (480px, 12fps) → send directly (auto-compresses)
• Twitter: Video to GIF (640px, 15fps) → upload (converts to MP4 on display)
• WhatsApp: Trim video to <6 sec → send as video (better than GIF conversion)
• TikTok/Reels: Crop to 9:16 → Speed up if needed → send as MP4
• GitHub: Video to GIF (640px, 15fps, <8 sec) → drag into README editor
• Email: Video to GIF (320px, 10fps, <3 sec) → embed or attach
