MP4 to GIF Optimization FAQ
How short / long should my MP4 clip be for a good GIF?
+
Animated GIF is best for clips under 10 seconds. Longer than that and the file balloons for GIF (which is uncompressed per frame). For longer animations target animated WebP, AVIF, or APNG — all three compress similarly to a real video codec.
What is the file size of a 5-second GIF animation from an MP4 clip?
+
GIF: 2-8 MB at 480p depending on motion complexity. Animated WebP: 200 KB to 1 MB at the same resolution. Animated AVIF: even smaller, often 100-500 KB. WebP / AVIF are 5-10x more efficient than GIF — use them whenever the platform you ship to supports them.
Will the GIF animation have audio?
+
No — animated GIF formats (GIF, WebP, AVIF, APNG) do not store an audio track. If you need sound, target a video format (MP4, WebM) instead of GIF.
Can I make the GIF animation loop forever?
+
Yes. The Loop setting makes the GIF repeat forever (the default) or play once and stop. There is no setting for a specific number of repeats. The loop flag is stored in the file, and most viewers respect it.
Why does my GIF look choppy compared to the MP4?
+
Two common causes: frame-rate downsampling (15 fps GIF vs 30 fps source — fix with the frame-rate option) and palette quantization on GIF (only 256 colors per frame — switch to animated WebP or AVIF for full 24-bit color and smooth gradients).
Is my MP4 private during GIF conversion?
+
Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted GIF are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
How long does the MP4 to GIF encode take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Does the GIF preserve transparency from the MP4?
+
Animated GIF supports single-color transparency only (binary mask). Animated WebP, AVIF, and APNG support full alpha channels. MP4 sources without an alpha channel (most camera footage) produce fully-opaque GIF regardless of format.
Can I share the GIF on Discord / Slack / Twitter / iMessage?
+
Animated GIF plays everywhere. Animated WebP plays on Twitter, Discord, and every modern browser but not on iMessage or older Slack clients. AVIF support is growing but still patchy on chat apps. For maximum compatibility ship GIF; for size ship WebP.
