Select any portion of a video and convert it to GIF. Set start time and duration precisely. Browser-based, no upload, no watermark.
Most videos are too long to convert to GIF in full — a 10-minute screen recording, a 2-minute product demo, or a 30-second clip from a downloaded video all need trimming before conversion. The key to a great GIF is identifying the exact 2–8 second window that captures the moment you want to share and nothing else.
GifSmith's clip trimmer gives you frame-level precision with a start time slider (set to any second in the source video) and a separate duration control. You can preview your chosen window before committing to the conversion, ensuring you get exactly the right moment without any wasted frames at the beginning or end.
The Start Time control scrubs through your video from 0 to the end of the file. Drop your video onto the forge and move the slider to find the frame where you want your GIF to begin. The Duration slider then sets how many seconds to capture from that start point.
For reaction GIFs: 1–3 seconds, tight crop to the key expression or moment.
For product demos: 3–8 seconds, capturing the key interaction or reveal.
For screen recording highlights: 4–10 seconds, showing the full interaction sequence.
Long source videos (downloaded MP4s, recorded meetings, tutorial footage) work just as well as short clips. GifSmith reads your video locally and seeks directly to your start point — the entire file doesn't need to be processed, only the segment you select. This means even a 2-hour video can produce a precise 5-second GIF clip without any slowdown.
Everything runs in your browser via WebAssembly FFmpeg. Drop your video, set start and duration, choose a quality preset, and hit STRIKE GIF. Your source file never leaves your device. Output is watermark-free and downloads instantly.
