How can I extract audio losslessly from a video on my windows 10 pc?

You can use Format Factory's Audio Extraction to extract audio from video on Windows 10. While Format Factory is known as a converter, its specific "Audio Extraction" function is a separate, lesser-used module.

Process: Install Format Factory (being vigilant to decline adware during installation). Navigate to the "Audio" tab on the left, and select "Extract Audio from Video." Add your file, and in the output settings, choose the format "Same as source" or a lossless format. It will demux or decode accordingly.

If you want to extract audio from video on Windows 10, Format Factory's audio extraction feature is a reliable and free choice. Just add your video, select the desired audio format, and start the extraction process. It’s a user-friendly way to get high-quality audio files from your videos.
