Convert MOV to GIF
Short answer
Drop your MOV file into the converter below and download the GIF file. It runs in your browser with FFmpeg, for files up to 100 MB; nothing is uploaded. The file is re-encoded to an animated GIF with no audio track. Re-encoding takes longer than a container swap and costs some quality; how much depends on the clip and on the quality setting, and at the converter's default setting the loss can be visible, so keep the original.
Maximum file size: 100 MB. The first conversion loads a ~30 MB converter engine, once per visit. Nothing is uploaded - conversion runs on your device.
GIF is a low-color, audio-free loop. · Lossy re-encode · Browser-side via FFmpeg WASM - nothing uploaded.
Key takeaways
- The converter writes the GIF at the source's full size and frame rate: our 1080p, 30 fps, 10 second clip became 44.2 MB from a 9.2 MB MOV (4.8 times bigger).
- GIF has no sound and at most 256 colors per frame, so quality fell to SSIM 0.67 against the video.
- Scaling to 480 px wide at 15 fps with a generated palette made a GIF of 8.7 MB from the same clip.
- For web playback an MP4 is far smaller: our GIF back to MP4 shrank by 92%.
Measured: converter defaults against a prepared GIF
Measured on a 10 second, 1920 × 1080, 30 fps excerpt of Big Buck Bunny (animated film, not camera footage; (c) Blender Foundation, CC BY 3.0) as H.264 plus stereo AAC 192 kbps, using the same ffmpeg arguments this converter passes to its WebAssembly build, run with ffmpeg 6.1.1. Results describe this file, not every file.
| GIF | Size | Frame size and rate | SSIM vs video |
|---|---|---|---|
| Converter default | 44,178,243 bytes | 1920 × 1080, 30 fps | 0.6707 |
| Converter default, 3 s excerpt in the browser core | 20,380,147 bytes | 1920 × 1080, 30 fps | not run |
| Prepared: 480 px wide, 15 fps, palette | 8,665,621 bytes | 480 × 270, 15 fps | not run |
The default GIF is also very large per second: about 4.4 MB for each second of video at full size. Browsers and chat apps often refuse or choke on files that size.

Need a smaller GIF?
This converter keeps the video's full frame size and frame rate, which is exactly what makes GIFs large: on a 5 second 1920 × 1080 excerpt it wrote 27.68 MB. The Video to GIF tool lets you pick the width, frame rate and length and builds the palette from your clip: the same excerpt was 1.81 MB at 480 px and 12 frames a second.
How to make a small GIF in a terminal
ffmpeg -i in.mov -vf "fps=15,scale=480:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" out.gif- palettegen builds a palette from your clip and paletteuse applies it; FFmpeg's filter documentation describes both.
- Halve the width to cut the size by about three quarters; halve the frame rate to cut it by about half.
Why GIF is silent and limited
GIF stores each frame with at most 256 colors and no audio track. If you need sound or smooth gradients, keep an MP4. A GIF is for short, low-motion loops.
Questions people ask
Is this MOV to GIF converter free and private?
Yes. It is free, needs no account and runs entirely in your browser, so the file never leaves your device.
Will converting MOV to GIF reduce quality?
Some, because GIF is lossless, but limited to 256 colors and the file is re-encoded. How much depends on the clip and on the quality setting, and at the converter's default setting the loss can be visible, so keep the original. For uploads, the platform re-encodes again anyway.
Is there a file size limit?
Files up to 100 MB. The first conversion downloads a converter engine of about 30 MB once per visit; larger files are better handled by a desktop app such as HandBrake or FFmpeg.
Why is my GIF so large and silent?
GIF stores every frame with at most 256 colors and no sound, so it is far larger than the same clip in MP4. Keep GIFs short and small, or post MP4 where the platform accepts it.
Why is my GIF so large?
The converter keeps the video's full frame size and frame rate. Our 1080p, 30 fps clip became a 44 MB GIF.
Can GIFs have sound?
No. GIF has no audio.
How do I get a smaller GIF?
Scale the width to 480 px or less, use 12 to 15 fps and a generated palette, and keep the loop short.
Is MP4 better than GIF?
For almost every use except places that only accept images. Our GIF converted back to MP4 shrank by 92%.
