よくある質問
- How long should my GIF be?
- 3-10 seconds is the sweet spot. Longer GIFs become large quickly due to GIF's inefficient compression.
- What does FPS control?
- Frames per second. Higher FPS = smoother motion but larger file. 15 FPS is a good default for most reactions.
- What is the typical GIF file size?
- A 5-second 480px wide 15fps GIF is usually 1-3 MB. Mobile-sharing-safe when under 5 MB.
- Does the GIF have audio?
- No — GIF is a still-image format that does not support audio. Video is converted visually only.
- Is my MP4 uploaded?
- No. Everything runs in your browser via FFmpeg.wasm.
- Can I reduce GIF size after conversion?
- Yes — pick a smaller width (320-480px), lower FPS (10-15), or shorter duration to reduce size by 2-5×.
