How to convert WebM to AVI
Upload your WebM file
Drag and drop a WebM file to turn into AVI, or click to browse. Anything under 1GB, and nothing is installed.
Confirm AVI as the output
AVI is already selected, so there is nothing to configure. Switch to another format in the panel if WebM needs to go somewhere else.
Convert and download
We convert the WebM on our servers, usually in under a minute. Create a free account to download the AVI.
Why convert WebM to AVI?
WebM is the open, royalty-free container built for the web. It is what most browser-based screen recorders produce, and VP9 packs the same picture into noticeably less data than H.264.
The practical problem: Most editing software, phones and TVs will not open a WebM file. Social platforms and messaging apps frequently reject the extension outright. Safari and older Apple devices handle WebM inconsistently.
AVI solves that. Widely readable by desktop players from the same era.

WebM to AVI questions
Is the WebM to AVI converter free?
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the AVI itself beyond the free-plan badge.
Do I need to install any software?
No. The conversion runs on our servers and you use it from a browser tab, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where WebM plays: Chrome, Firefox and Edge; hit and miss elsewhere. Where the AVI you get back plays: Desktop players with the right codec pack.
Does converting WebM to AVI reduce the quality?
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the WebM on normal viewing. What changes is the container and the codec. AVI holds: DivX, Xvid, MJPEG and other legacy codecs. Converting the same file back and forth repeatedly will eventually show, so keep your original.
How large a file can I convert?
Anything under 1GB per upload, which is more footage in some formats than others. WebM: Very small at the same quality. AVI coming back: Very large for the quality. For anything bigger, trim or compress it first, both are free tools here.
Is my file kept private?
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
