Some platforms and web tools specifically call for WebM, and finding out your video is in the wrong format after you have already tried to upload it is a frustrating way to learn that. The Video to WebM Converter on File Tools Online turns your video into the WebM format, a format built specifically for playing smoothly on the web. Upload your video, let the tool process it, and download the WebM version.

WebM is an open, royalty-free video format developed specifically for use on the web, built to play natively in browsers through HTML5 video without needing an extra plugin. It generally uses efficient video and audio codecs designed to keep file sizes down while still looking good, which is part of why it is a common choice for embedding video directly on websites.
The exact codecs this tool uses internally, most commonly VP8 or VP9 for video and Vorbis or Opus for audio in a standard WebM file, are set inside the tool's own configuration and are not something we can confirm without testing the live tool directly. Whichever combination it uses, the result is a video file built around the same open standards that made WebM a natural fit for the web in the first place.
Needing a video in WebM format comes up constantly for anyone publishing video directly on a website or working with web-focused tools. Most of these situations trace back to the same reason WebM exists in the first place: a format built specifically to be efficient and reliable inside a browser, rather than adapted from formats designed for cameras or editing software.
A lot of search interest around WebM is actually about the opposite direction from what this tool does: taking a WebM file you already have and turning it into MP4, generally because MP4 is more universally supported across devices, editors, and platforms. If that is what you need, this is not the right tool, this Video to WebM Converter takes a video in another format and turns it into WebM, not the other way around.
File Tools Online's Video Converter handles any video format, including WebM, and converts it to MP4, that is the tool to use if you have a WebM file and need MP4 instead. Keeping the two directions straight before you upload will save you a round trip: use this tool to go into WebM, use the Video Converter to go out of WebM and into MP4.
The tool accepts common video formats such as MP4 and MOV as a source file to convert into WebM. If your source file is in a less common format, run it through the Video Converter first to get it into MP4, then convert that result to WebM. Confirm the full accepted format list against the live tool if you are working with an uncommon container or codec. Footage exported straight from a phone or a screen recording app is usually already MP4 or MOV, so most people can upload directly without an extra conversion step first.
WebM is generally known for efficient compression, so converting to it often produces a smaller file than the original, though the exact balance between file size and visual quality this tool uses is set inside its own configuration and is not something we can confirm without testing it directly. As with any video format conversion, some quality loss is possible, particularly if your original file is already heavily compressed, converting a compressed file again rarely improves on the original. If you need the smallest possible WebM file and are not satisfied with the default result, running the output through the Video Compressor afterward gives you a second pass at reducing file size.
Converting a video to WebM traditionally meant installing dedicated encoding software and learning its settings. The Video to WebM Converter on File Tools Online skips that step entirely. There is nothing to download and nothing to install, whether you are on Windows, Mac, Android, or iPhone, you upload your video directly in your browser and download the WebM result. For a quick, occasional conversion, that is generally faster than installing and configuring dedicated encoding software.
Because the Video to WebM Converter runs in your browser rather than as installed software, it works the same way on Windows, Mac, Chromebook, Android, and iPhone. There is nothing tied to one operating system, so you can convert a video to WebM on whichever device you happen to have it on.
