Convert WEBM to GIF

A browser recording or a downloaded WEBM needs to become a GIF for a ticket, a wiki or a chat client that will not play video.

Where the streams already fit the target container this is a lossless remux, which is close to instant. Otherwise it re-encodes, which in a browser is slow — keep it under a few hundred MB and send long videos to the cloud engine.

    What actually changes

    WEBM and GIF are not the same picture in two wrappers.

    Frames are decoded from VP8 or VP9, resized, quantised to 256 colours and written as a GIF. Sound is dropped.

    Worth knowing first

    Screen recordings are the worst case for GIF. Text and UI chrome are full of fine detail and hard edges, which survive quantisation badly and defeat GIF's LZW compression, so a 2 MB screen capture can produce a 30 MB GIF.

    Questions

    WEBM to GIF, answered

    How do I make screen recordings smaller?

    Crop to the region that matters and drop to 10 or 12 frames per second. Cropping saves more than any other setting.

    Does transparency survive?

    WEBM can carry an alpha channel and GIF only has one transparent index, so soft edges become hard ones.

    How to convert WEBM to GIF

    01

    Add your files

    Drop one WEBM or two hundred. Batch conversion is not a paid feature here.

    02

    Choose your settings

    Graphics Interchange Format is lossy, so the quality control decides the trade between size and fidelity.

    03

    Download

    Instant, because the file never went anywhere. Nothing expires, since nothing was stored.
