StreamFab YouTube Downloader Pro

Download YouTube videos, music, playlists, and live streams in up to 8K quality
Save videos as MP4/MKV/FLV or extract audio as MP3/M4A for flexible offline playback

Support H264, VP9 or AV1 codec

Many YouTube videos are now delivered in VP9 or AV1 in addition to H.264. StreamFab gives you the flexibility to choose the codec you prefer, which matters if you want to balance playback compatibility, compression efficiency, and overall file size.

H.264 remains the most broadly compatible option across older and newer devices, while VP9 and AV1 are better suited to many modern devices and supported players. Instead of taking whatever format happens to be available, you can save videos in a version that better matches the way you actually watch them.

Save YouTube videos in MP4/MKV format

StreamFab YouTube Downloader Pro supports saving videos in MP4, MKV, or FLV format, making it easier to watch your downloads across different devices, apps, and media players. Whether you prefer a broadly compatible format or need a container that better fits your playback setup, you have more control over the final file.

That flexibility is especially useful if you want to archive content on your PC, move files to another device, or build an offline library you can keep organized over time.

320 kbps Hi-Fi M4A/MP3 Music

If you only need the audio, StreamFab lets you save YouTube content as MP3 or M4A with multiple quality options, including up to 320 kbps. This is useful when you want music, lectures, interviews, podcasts, or other spoken content without downloading the full video file.

Audio-only downloads also make offline listening simpler on devices where storage space matters more. Instead of keeping a large video file for content you mainly listen to, you can save a smaller file that is easier to organize and play anywhere.
