Frequently asked questions
- Is the video uploaded anywhere?
- No. The conversion happens entirely inside your browser using ffmpeg compiled to WebAssembly. We never see your file.
- What's the maximum file size?
- 500 MB. The hard limit is your browser's available memory — the cap stops the engine from crashing on multi-GB inputs.
- Why is the first conversion slow to start?
- We download the in-browser video engine (around 30 MB) the first time. After that, every conversion in this tab runs instantly without re-downloading.
- Which video formats are supported?
- Anything ffmpeg understands — MP4, MOV, MKV, WebM, AVI, FLV, 3GP. The output is always a single GIF.
- How do I make the GIF smaller?
- Pick the Small preset, lower the fps (8–12 is plenty for chat), and trim to the shortest segment you actually need. A 5-second 320 px GIF at 10 fps is usually well under 2 MB.
- Why does the colour quality look better than other online GIF makers?
- We use ffmpeg's two-pass `palettegen → paletteuse` pipeline with Bayer dithering, which produces a custom 256-colour palette per video instead of dithering against a fixed web palette.
- Can I trim the video before converting?
- Yes. Type a start and end timestamp (e.g. 0:05 and 0:12) to pull a short window out of a longer clip — useful for capturing one specific reaction.
- What's the maximum GIF length?
- Technically unlimited, but anything over ~10 seconds at 480 px gets very large and chat platforms often refuse files over 8–16 MB. Trim aggressively for sharing.
- Does this work on mobile?
- Yes, in Chrome and Safari on iOS/Android — but phones with under 4 GB of RAM may struggle on long clips. We show a soft warning when we detect low memory.
- Is the video-to-GIF converter free?
- Yes — completely free, no signup, no watermark, no upload.
