MP4, MOV, AVI and WebM are all supported. The maximum file size is 100MB.
Is my video uploaded to a server?
No. Everything runs locally in your browser using FFmpeg.wasm. Your videos never leave your device.
Why are your GIFs smoother than other tools?
We use FFmpeg.wasm with advanced dithering algorithms (Floyd-Steinberg and Sierra) and a two-pass palette generation process — the same techniques used by professional video tools.
What is the free daily limit?
Free users can generate 3 GIFs per day and clips up to 3 seconds long. Upgrade to Premium for unlimited generations and any clip length.
What does Premium unlock?
Premium unlocks unlimited GIF generations, clips longer than 3 seconds, Ultra Smooth quality mode (Sierra dithering), and 30fps output. See the full breakdown on our Premium page.
Can I cancel my Premium subscription?
Yes, cancel any time. Your premium access continues until the end of your billing period. Email us at TwentyOneToolsSupport@gmail.com if you need help.
