Making a GIF from a video without ending up with a huge file
2026-10-01
GIF is a format from 1987. It has no modern video compression: every frame is stored as a separate 256-colour image. That is why a clip that is 2 MB as an MP4 can easily become 20 MB as a GIF. Three things control the size, and all three multiply together.
- Length. Twice as long is roughly twice as big.
- Dimensions. Twice as wide is four times the pixels.
- Frame rate. More frames per second means more images.
What the quality settings produce
| Setting | Frame rate | Width | Good for |
|---|
| High | 15 fps | 640 px | Tutorials and screen recordings where text must stay readable |
| Medium | 12 fps | 480 px | Most reactions and clips |
| Small | 8 fps | 320 px | Chat apps with strict size limits |
Height is scaled automatically to keep the shape of the original video.
Trim the video first
The converter turns the whole video into a GIF; it does not have a trim tool. Cut the clip down to the few seconds you need before converting. The Photos app on iPhone, Google Photos on Android, and the built-in video apps on Windows and macOS can all trim a clip in a few taps. Aim for under ten seconds.
Steps
- Trim the clip to the part you want.
- Convert with MP4 to GIF, MOV to GIF or WEBM to GIF. Start with Medium.
- Check the size shown next to the download button. If it is too large, convert again on Small.
When a GIF is the wrong tool
If the destination accepts video, a short MP4 looks better and is far smaller. Most social platforms convert uploaded GIFs to video behind the scenes anyway. Use a GIF when you need something that plays automatically with no player: documentation, README files, email, and forums that only allow images.
Two more limits to keep in mind: GIFs have no sound, and the 256-colour palette makes smooth gradients such as skies and skin tones look banded. Screen recordings and animation survive the conversion much better than camera footage.
