This is an estimate, not an exact file size
Actual size depends on content, palette construction, dithering, frame differences, and the encoder.
Estimation model
size ≈ frames × width × height × (log₂(colors) / 8) × factor
Frames = duration × fps. Conversion uses 1 MB = 1,000,000 bytes.
Platform limit check
Statuses use the current estimate. Platforms can change their rules, so recheck the linked official source before publishing.

No stable global GIF cap is published; community and client rules vary
Reddit HelpVerified August 6, 2026. A general file limit does not guarantee inline GIF playback, and workspace, community, client, or admin policies may impose lower limits.
How to get under the limit
Each target assumes one change at a time. For complex footage, combining two changes is usually safer.

Frequently asked questions
How accurate is this GIF size estimate?+
It is useful for comparing settings before export, but it cannot replace a real encode. Frame differences, local palettes, dithering, and the encoder all affect final size.
Why does motion complexity affect file size?+
GIF LZW compression benefits from repeated pixel patterns. Static backgrounds compress better, while fast motion, noise, and dithering create more changing data.
What is the most effective way to shrink a GIF?+
Reduce dimensions first, then lower frame rate or duration. Fewer colors also help, but can be more visible in gradients and detailed scenes.
Why is an MP4 usually smaller than the same GIF?+
Modern video codecs predict across frames and use more efficient compression. GIF has a limited palette and an older compression model, so longer animation is usually better as MP4.
