How to use
- Choose an MP4, WebM or MOV file.
- Play the video and use "Use current" to set the start and end, or type the seconds.
- Pick the frame rate, width, colours and speed.
- Create the GIF, check the preview and download it.
Options explained
- Frames per second
- 10–15 fps looks smooth for most clips. Every extra frame adds to the file size, because GIF stores each frame as a full image.
- Width
- 480 px is a good default for chats and documents. Halving the width makes the file about four times smaller.
- Colours
- GIF allows at most 256 colours per frame. Fewer colours make smaller files but can cause banding in gradients and skin tones.
- Speed
- Plays the clip faster or slower without changing the number of frames.
How the frame count and speed are worked out
The number of frames is the clip length times the frame rate, rounded down. A GIF holds at most 450 frames. Each frame is shown for 1000 ÷ frame rate ÷ Speed milliseconds, with a floor of 20 ms. GIF itself stores delays in hundredths of a second.
| Frames per second | Frames in a 5 s clip | Longest clip (450 frames) |
|---|---|---|
| 5 | 25 | 90 s |
| 10 | 50 | 45 s |
| 15 | 75 | 30 s |
| 20 | 100 | 22.5 s |
| 25 | 125 | 18 s |
At 10 fps, Speed 0.5× shows each frame for 200 ms, 1× for 100 ms, 1.5× for 66.7 ms and 2× for 50 ms. The frame count stays the same.
The chosen Width is never enlarged beyond the video, the height follows the aspect ratio, and both are rounded to even numbers. A 1920 × 1080 video at 480 px becomes 480 × 270.
Frequently asked questions
Why is my GIF so large?
GIF is an old format with weak compression. Shorten the clip, lower the frame rate or width, or reduce the colours. For long clips a short MP4 is usually a better choice.
Is there a length limit?
Up to 450 frames per GIF, for example 45 seconds at 10 fps or 18 seconds at 25 fps.
Which videos work?
Any video your browser can play. MP4 (H.264) and WebM work everywhere; HEVC/H.265 and MOV files from iPhones play in Safari and in some other browsers.
Is sound kept?
No. GIF has no audio track.
