How to convert WebM to GIF
Drop your WebM file above. The first five seconds are selected; change the start andend, or play the video to the moment you want and press Start at player position. Choose a width and frame rate, check the size estimate, then press Make GIF. Watch it loop, and download it.
Screen recordings to GIF
Most browser screen recorders and Chrome extensions save WebM. Turning a short recording into a GIF is the easy way to show a bug, a feature or a how-to step in places that only take images: GitHub issues and READMEs, documentation, email and help-desk tickets. Screens have large areas of flat colour, so these GIFs stay small — 480 or 640 px wide at 10 fps is usually plenty.
Crop and trim first
If the recording shows your whole screen, crop it to the window that matters before making the GIF — a smaller picture is both easier to read and a much smaller file. The range settings here already trim the start and end.
GIF or MP4?
Slack, Discord, X and most chat apps play a short video on a loop just like a GIF, at a fraction of the size. If the clip is going somewhere that plays video, WebM to MP4 is usually the better choice. Use a GIF where only images work.
Other formats
For MP4 and other videos, use the Video to GIF converter; for iPhone and QuickTime files, MOV to GIF.
Frequently asked questions
How do I convert WebM to GIF?
Drop the WebM file above, choose the part you want — the first five seconds are selected for you — pick a width and frame rate, and press Make GIF. Preview the result, then download it.
Where do WebM files come from?
Browser-based screen recorders, Chrome extensions, online meeting tools and many websites save video as WebM. It plays in browsers but not in many other places, which is why people turn it into a GIF or an MP4.
Should I make a GIF or an MP4?
Make a GIF where only images work: README files, documentation, email, forums. Where video works — Slack, Discord, most social networks — an MP4 is smaller and looks better. WebM to MP4 makes one that plays everywhere.
Why is my GIF bigger than the WebM?
A GIF saves every frame as a separate picture, so it is usually much larger than the video. Shorten the clip, lower the width, or drop to 10 fps to make it smaller. The size estimate under the settings updates as you change them.
Does it work with transparent WebM?
The GIF is made on a solid background, so transparent areas come out filled. For animations that need transparency, export a transparent GIF from the program that made the animation.
Is my video uploaded?
No. The GIF is made inside your browser. Your video never leaves your device, and there is no watermark or sign-up.
