YouTube to MP4 HD MP4 that plays anywhere

Quick answer

To convert YouTube to MP4, paste the video link into DownloadReel and choose a resolution. The video is saved as an MP4 with H.264 video and AAC audio, the most compatible format there is, so it plays on Android, iPhone, Windows, Mac, smart TVs and in editing apps.

What "MP4" really means

MP4 is only the container. What decides whether a file plays is the codec inside it. Many YouTube downloads come out as MP4 files with VP9 or AV1 video, which some devices can't decode. DownloadReel's MP4 files use H.264, which practically every device supports.

MP4 sizes at a glance

1. 1080p: best for TVs and computers; the biggest file.
2. 720p: sharp on phones and laptops; roughly a third of the 1080p size.
3. 480p and 540p: good balance for sharing in chats.
4. 360p: smallest file, fine for quick previews or slow connections.

Editing the MP4

Because the file is H.264 + AAC, it opens directly in CapCut, InShot, iMovie, Premiere Pro, DaVinci Resolve and Windows' Clipchamp without converting it again.
