What it does
This tool turns part of your own video into an animated GIF. Your browser steps through the video frame by frame, reduces each frame to 256 colours and writes the GIF itself, so nothing is uploaded and it keeps working offline once the page has loaded.
GIFs play almost everywhere but are large, so short clips work best. To cut a longer video first, use the video trimmer; to make a GIF of something on your screen, record it with the screen recorder and open the recording here.
How to use it
- Press Open a video and choose a video your browser can play.
- Set the start and end with the sliders or the time boxes, or play the video and use Start at the current frame and End at the current frame.
- Choose the width, frames per second, colours and loop.
- Press Make the GIF, watch the progress bar, then Download the GIF.
What each setting does
- Start and End: the part of the video to use, in seconds.
- Width in pixels: 80 to 800; the height follows the video’s shape. A video is never made larger than it is.
- Frames per second: 5 to 20. More is smoother but makes a bigger file.
- Colours: Best works out 256 colours for each frame (median cut). Fixed uses the same 252 colours for every frame: faster, but skin and skies can look banded.
- Loop forever: on, the GIF repeats; off, it plays once and stops.
The line under the settings shows the number of frames and an estimated size, worked out by encoding the first frame and multiplying. A clip can have at most 300 frames.
Worked example
A 1280 × 720 phone video, clip from 2 to 5 seconds, width 320, 10 frames per second: that is 3 seconds × 10 = 30 frames of 320 × 180 pixels, each shown for 0.1 s.
FAQs
Why is 15 frames per second not exact? GIF stores how long each frame shows in hundredths of a second, so 15 fps becomes 0.07 s per frame (about 14.3 fps).
Does the GIF have sound? No. GIF is a picture format with no sound.
How do I make the file smaller? Shorten the clip, lower the width or the frames per second.
Where the numbers come from
- GIF89a file format (CompuServe Graphics Interchange Format, version 89a, 1990) with LZW compression; median-cut colour reduction (Heckbert, 1982). Encoder is fibub's own working.
