What is Video Converter?

Video Converter is a user-friendly Chrome Extension designed for simple video conversions in the browser. Using the FFmpeg library compiled with the Emscripten compiler, it allows you to convert video file formats by dragging a file to the designated area, entering an FFmpeg command, and initiating conversion. Despite running slower than native FFmpeg applications, it's an ideal tool for straightforward video conversion tasks, operating without additional plugins. Note, this tool is not designed for audio conversion.

Video Converter extension helps you easily convert any video format to another (for example, WEBM to MP4). It uses the FFmpeg library which is compiled from C/C++ language to JavaScript with Emscripten compiler. Emscripten is a source-to-source compiler that can compile native C/C++ codes to JavaScript language. Please read this Wikipedia page to get more info about the Emscripten compiler.

To work with this add-on, just open the app UI and drag a video file to the designated area in the app. Then, type your FFmpeg command in the input file and press the - Run - button. Once the conversion is done, the link to download the video file will be available at the bottom of the UI. Please note that conversion may take some time depending on the video size and also the type of conversion that you choose. There are some sample commands available in the app UI (as buttons) which you can use to start working with this add-on.

Note: Since this add-on runs FFmpeg in the browser, it runs slower than the native FFmpeg applications/library. However, using the add-on is very easy. Simply add it to your browser and it starts to work without any additional plugins. It is only suitable for simple conversions and has a limited number of codecs.

Note: This add-on is specifically designed for "video" conversion. If you want to convert an "audio" file, please use my other add-on Audio Converter (
