How it works

  1. Step 1

    Choose a clip

    Drop a video or pick a file, up to 250 MB and 10 minutes.

  2. Step 2

    Set length, width and frame rate

    Shorter, narrower and fewer frames make a smaller GIF. 5 seconds at 480 px and 12 frames a second is a good start.

  3. Step 3

    Make it and download

    The GIF is built on your device with a palette made from your clip, then checked against X’s limits.

What decides the size of a GIF

A GIF stores every frame with a palette of at most 256 colours and compresses far less efficiently than video, so the file grows with three things you control: how long it is, how wide it is, and how many frames a second it plays. Halving the width cuts each frame to about a quarter of the pixels; halving the frame rate halves the frames.

This converter builds one colour palette from your clip before encoding, which keeps gradients and skin tones from banding.

GIF limits on X

From X’s help page on posting photos and GIFs. The converter tells you which limit your GIF fits.

RuleLimit
Animated GIF sizeUp to 5 MB on mobile, up to 15 MB on the web
GIFs per postOne, and not combined with photos
Tagging peopleNot possible on an animated GIF

When to post a video instead

GIFs have no sound. If the clip needs its audio, such as someone speaking, post it as a video. For reactions, loops and short demos without sound, a GIF autoplays and loops.

Frequently asked questions

Everything you need to know before you start.

Choose the video, pick a length (5 seconds is a good start), a width such as 480 px and a frame rate such as 12, and select Make GIF. It runs in your browser and downloads a looping GIF.

X allows animated GIFs up to 5 MB on mobile and 15 MB on the web. Reduce the width first, then the frame rate, then the length. The converter shows which limit your GIF fits.

No. The GIF is made on your device with FFmpeg running in WebAssembly. Only the converter itself is downloaded, once, and checked against a fingerprint before it runs.

GIF stores each frame with a palette of up to 256 colours and compresses poorly compared with video, so length, width and frame rate multiply the size. Halving the width saves the most.

No. The GIF format has no audio track. Post clips that need sound as video.
