When Video Downloader Plus detects a video stream, you can pull it down to your device at any quality the stream makes available. The download process handles everything — manifest parsing, concurrent segment fetching, and audio/video merging — without requiring any additional software.

HLS and DASH stream downloads

Adaptive streams are segmented — the video is split into dozens or hundreds of small chunks spread across separate files. Video Downloader Plus handles the entire download pipeline:
  1. Parses the manifest file to map out every video and audio segment
  2. Fetches multiple segments at the same time for faster overall download speed
  3. Reassembles them into a single, contiguous media file
  4. Optionally remuxes the result into your chosen container format
Additional capabilities for adaptive streams:
  • Parallel segment fetching — Concurrent connections mean faster downloads, especially for longer videos
  • Retry on interruption — If a download stalls, you can restart it without losing progress
  • Automatic audio merging — When a stream carries audio and video in separate tracks, Video Downloader Plus combines them into one file automatically
  • Full quality selection — Every variant declared in the manifest is available to choose from
  • Live stream recording — Capture ongoing live broadcasts (Professional plan)

Progressive video downloads

For direct video files served over HTTP — MP4, WebM, MKV, and similar formats — Video Downloader Plus downloads the file as-is. File size is shown upfront when the server includes a Content-Length header.

Download limits

Free users:
  • Unlimited downloads at 720p and below
  • 3 Full HD (1080p) downloads per day
  • The daily count resets at midnight
Professional users:
  • Unlimited downloads across all quality levels
  • No daily caps
The 1080p daily limit is tracked per device. If you’re signed into a Video Downloader Plus account, it ties to your account instead, preventing the limit from being reset by switching browsers.

Supported formats

Video Downloader Plus can download content in 16+ container formats:
CategoryFormats
Common videoMP4, WebM, MKV, MOV
Transport streamTS, M2TS, MTS
LegacyAVI, WMV, FLV, MPG, 3GP, OGG
AudioMP3, AAC, M4A, FLAC, WAV
Converting HLS or DASH streams into MP4, MKV, MOV, or WebM is a Professional feature. Free users receive the native stream format.

Download settings

You can adjust download behavior from the options page:
  • Download management — Activates the browser’s download management API, giving you more control over save location and file naming. This requires a separate optional browser permission, requested at runtime.
  • Download path — Set a folder prefix so Video Downloader Plus organizes files into a subdirectory (e.g., Video Downloader Plus/ inside your Downloads folder).
  • File naming — Filenames are generated from the video title and deduplicated automatically by appending a number if a file with the same name already exists.
