Convert MP4 to GIF Online — No Upload, No Watermark
GIF is still the king of inline animations on Slack, GitHub, Reddit, and old-school chat apps. Converting MP4 to GIF turns short clips into shareable, autoplaying loops.

Where MP4 files come from
A GIF is what you reach for when the destination will not autoplay a video: an email, a README on GitHub, a wiki page, a chat client that only previews images.
What changes when you convert MP4 to GIF
| Format | Video frames become a palettised animated image |
|---|---|
| Colours | Reduced to 256 per frame |
| Audio | Dropped entirely, since GIF has no sound |
| File size | Usually grows sharply compared with the MP4 |
Worth knowing first
GIF has no compression between frames, so a few seconds can be many times larger than the MP4 it came from. Keep clips under about five seconds, drop the frame rate to 10 or 15, and reduce the width. If the destination accepts video at all, it is the better answer.
FAQ
Why is my GIF bigger than the video?
Because GIF stores every frame as a complete image with its own palette, while H.264 stores mostly the differences between frames. That is the whole reason video codecs exist. Shorter, smaller and slower GIFs are the only lever you have.
How do I keep the GIF small?
Cut the length first, since size scales almost linearly with duration. Then drop to 10 or 15 frames per second, which reads fine for short loops, and reduce the width to what the page actually displays. Those three together usually bring a file down by an order of magnitude.
Where did my audio go?
GIF has no concept of sound and never has. If you need audio, the destination needs to accept video, and an MP4 or WebM is the right file.
Is this MP4 to GIF converter really free and without upload?
Yes. The tool runs entirely in your browser using FFmpeg compiled to WebAssembly. Your MP4 file never leaves your device — open the DevTools Network tab to verify zero uploads. No signup and no watermark. The practical size limit is the memory your browser gives this tab, which is generous on a computer and a few hundred megabytes on a phone.
