Therefore, use this app for lite to moderate tasks and expect sudden crashes or errors while converting the video file (although it is rare). Since this project runs inside your browser via the Javascript engine, it has a lower performance comparing to the original FFmpeg engine in native platforms. Please note that this app uses FFmpeg library in Javascript which is a compiled version of the original FFmpeg library with Emscripten project. But, for advanced users, the command area can be edited to perform a more advanced conversion process. These commands are for those who are not familiar with FFmpeg. Pressing on each button will insert the corresponding command in the input area with a valid output file extension. There are 5 sample commands for converting video files in the app.

The wrong file extension will result in the FFmpeg process error. To add a correct output file extension you need to be familiar with FFmpeg commands and codecs. Please note that the final file extension needs to be correct depending on the conversion command you enter. You can see all the process info in the console area moreover, when the converting process is done, a preview for the final video will also be shown. Wait for the converting process to finish and then download the result to your system. When the command is ready, please click on the - Run - button at the top right corner. If you are familiar with FFmpeg commands, you can edit the command or insert your own.

Then, click on a sample command button to insert an FFmpeg command in the input field. Simply drop a video file in the designated area within the app (top section). This web application is designed to convert video files.
