WebM to GIF, with colour that holds up
Browser-based screen recorders save WebM. Bug trackers, documentation and support threads want GIF. This closes that gap without the muddy colour most converters produce.

What happens when you drop a file in
The file stays put. Your browser opens it the same way an image viewer would. There is no transfer, which is why there is no upload bar to watch.
An encoder arrives once. The first job on this site pulls down a compiled build of FFmpeg, roughly 30 MB. It is kept afterwards, so every job after the first starts immediately.
Your own hardware does the job. The work happens in this tab, on your processor. A laptop from the last few years handles short clips in well under real time.
The result lands in Downloads. Assembled in memory and handed straight to your browser. Close the tab and every trace of it is gone.
Why this particular pairing comes up so often
Screen recorders that run in a browser almost all produce WebM, because that is what browsers can encode natively. Meanwhile the places those recordings end up — issue trackers, documentation, support conversations — want a GIF, because a GIF plays inline where an embedded video does not.
So a very common sequence is: record a short interaction, then immediately need it in a format the recorder never offered. That gap is the entire reason this page exists.
There is a happy coincidence in it. Screen recordings are close to the ideal GIF source — large flat areas of colour, limited motion, short duration. They survive the 256 colour ceiling far better than camera footage ever does.
Ten seconds is the practical ceiling
GIF carries nothing between frames, so size grows almost in step with length. Ten seconds at 480 pixels wide lands around three to six megabytes; twenty seconds doubles it, and most places that accept GIFs cap uploads well below that. Trim before converting rather than after, because there is nothing to be recovered afterwards.
Common questions
Why is the GIF so much bigger than the WebM?
GIF stores each frame independently with no modern compression at all. A tenfold increase is entirely normal.
The colours look flatter.
256 per frame is the format's hard limit. Choosing the best 256 for your clip, as this does, gets closer than most tools, but gradients still band.
Should I use a GIF at all?
If the destination accepts video, no — video is smaller and sharper. GIF wins only where autoplay is required and video is refused.
Is the recording uploaded?
No, the conversion runs entirely in this tab.
