Video saving and stream guides
How to save HLS (M3U8) video
HLS delivers video in small segments. An .m3u8 file is a playlist that points to those segments and possible quality variants; it is not the finished movie. Vidsavo can find supported HLS media on a page and assemble accessible segments into an offline file.
When HLS downloading makes sense
You are watching your own webinar, a permitted course recording, or another video that the rights holder allows you to save. Rather than exposing a direct MP4 URL, the player requests an m3u8 playlist and video segments.
- The source may offer different resolutions, such as 360p, 720p and 1080p.
- Audio and video sometimes arrive as separate streams. Combining them requires compatible tracks.
- Some stream URLs expire; a new request cannot guarantee renewed access.
Five steps to save permitted media
- Install Vidsavo from its official Chrome Web Store listing and open the permitted source page.
- Start playing the video that you have permission to save.
- Hover over a supported player or open the extension popup to find the video.
- Choose an available quality. During the free beta, all Pro features are available until December 31, 2026.
- Monitor progress in the download manager, save the file, and verify that both video and audio play correctly.
Why some m3u8 streams do not work
Not every streaming service provides ordinary HLS media. Sites may use DRM, access restrictions, unusual players or session-specific URLs. Vidsavo does not circumvent DRM or rights-holder restrictions.
- No download button: reload the page, start playback and check the extension popup.
- Video without sound: the audio stream may be separate, unavailable or incompatible.
- The download stops: a temporary URL may have expired or the source stopped serving segments.
- The file will not play: check the format and whether your media player supports its codec.
HLS versus a direct MP4
A direct MP4 is typically a self-contained media file. HLS comprises playlists and segments that must be fetched and assembled. Vidsavo automates the supported part of that process without promising that every site or protected stream will work.
Frequently asked questions
Can Vidsavo download any m3u8?
No. The source must be accessible, compatible and permitted to save. DRM is not supported.
How do I choose quality?
When the site offers multiple variants and Vidsavo detects them, choose the one you want from the download menu.
Will the MP4 include sound?
Compatible streams can be merged. Missing audio, unsupported codecs or a source that does not supply sound can affect the result.

Vidsavo works with accessible media on compatible sites. It does not support YouTube downloads or bypass DRM. Results can vary with the source player, browser and your permissions.
