Download an X GIF as a real .gif
When someone posts a GIF, X converts it to a short MP4 without sound. Our GIF downloads give you that MP4, which is smaller and sharper. If you need an actual .gif (for a chat app, a forum or a slide), convert it afterwards.

In short
- What X stores
- A silent MP4 (H.264), usually one rendition
- What we download
- That MP4, labeled GIF
- Real .gif
- Convert after downloading (ffmpeg, an editor or an online tool)
- Size change
- A .gif is often several times larger than the MP4
Step by step
- Download the GIF item. Paste the post link; the item is marked GIF. Click its button to save the MP4.
- Pick a converter. Desktop: ffmpeg (best quality). Phone: a converter app or a trusted online tool.
- Convert with a palette. Use the two-step palette method below; it avoids the banding of quick conversions.
- Check the size. If the .gif is too big, lower the width or the frame rate and convert again.
The ffmpeg recipe
GIF can only use 256 colors per frame, so the trick is to compute the best palette for this clip first, then apply it. Width 480 and 15 fps keep most reaction GIFs under a few megabytes:
ffmpeg -i clip.mp4 -vf "fps=15,scale=480:-1:flags=lanczos,palettegen" palette.png
ffmpeg -i clip.mp4 -i palette.png -lavfi "fps=15,scale=480:-1:flags=lanczos[x];[x][1:v]paletteuse" clip.gifWhy X uses MP4 for GIFs
Video codecs compress motion far better than the GIF format, so an MP4 of the same clip is typically a fraction of the size and keeps full color. That's also why our GIF download is an MP4: it's the best-quality file X has.
The MP4 has no audio track, so the MP3 button on GIF items always reports no audio track.
Keeping it a GIF on iPhone
If you save the MP4 to Photos it plays as a video, not as an animated image. Converting to .gif first (with a converter app or a Shortcut that uses “Make GIF”) and then saving the .gif keeps it animated in Messages and other apps.
Size and quality trade-offs when converting
A real .gif is far less efficient than the MP4 X stores. GIF supports only 256 colours per frame and has no inter-frame compression comparable to H.264, so a three-second MP4 of a few hundred kilobytes can turn into a GIF of several megabytes. Lowering the frame rate to 10–15 fps and the width to 320–480 px keeps the result shareable.
Many places that “need” a GIF accept MP4 today: most chat apps play short silent MP4s as looping animations, and slides in modern presentation software accept video. Convert only when the destination truly requires the .gif format, such as some forums, email signatures or older CMS fields.
Questions people ask
Can TwitterDownloaderX output .gif directly?
Not at the moment. We give you X's MP4, the best source, and you convert it.
Why is my converted GIF so large?
GIF stores every frame with limited compression. Lower the width or fps.
Do X GIFs have sound?
No, never.
