MOV to GIF Converter

iPhones, iPads and Macs record and screen-record video as MOV. To share a moment as a GIF — in a chat, a bug report, a README or a slide — pick where it starts and how long it lasts, and this tool turns that part into a looping GIF in your browser. Colours come from a palette built from the clip itself, so they stay close to the original. The ffmpeg engine is a one-time download of about 30 MB; your video is never uploaded.

How to use this tool

1. Choose a MOV file (MP4 works too).
2. Enter the start time and how many seconds to use; keep it short.
3. Pick the frame rate, width and speed: 10 fps at 480 px suits most chats.
4. Choose colours, dithering and looping, and download the GIF.

Formula

Frames = seconds used ÷ speed × frame rate

GIF size grows with width × height × frames, so halving the width roughly quarters the file. iPhone videos are usually HEVC (H.265); the engine decodes HEVC in software, more slowly than H.264, and a 4K frame has four times the pixels of a 1080p one, so keep the part short. Portrait videos stay upright; the width applies to the upright picture.

Example

3 seconds of an iPhone clip at 12 fps and normal speed gives 3 × 12 = 36 frames; at 480 px wide that is typically 1.5–4 MB. At 0.5× speed the same 3 seconds last 6 seconds as a GIF: 72 frames.
