HLS & M3U8 Video Downloader - VidNeatDown von HandanCorp

Download streaming videos, save HLS/M3U8 playlists, extract blob URLs, and convert media segments directly to MP4 in your browser. VidNeatDown is a fast, privacy-first, zero-server video downloader utility designed specifically for scenarios where standard browser downloads fail.

Reconstruct and save media from complex embedded players, live streams, and fragmented web sources locally on your computer—no third-party companion software, external converters, or remote servers required.



• Advanced HLS & M3U8 Downloader:
Automatically sniffs .m3u8 playlists and downloads fragmented media streams seamlessly in the background with maximum speed.

• True Local TS-to-MP4 Remuxing:
Reconstructs and remuxes HLS/TS transport segments into universally compatible, high-quality .mp4 video files. 100% lossless remuxing—no re-encoding, no visual degradation, and full audio sync.

• Separate Audio/Video DASH Muxer:
Intelligently combines separate audio and video streams (e.g. Vimeo, Reddit, and Twitter/X) locally into a single, complete MP4 video with crystal-clear sound.

• Blob URL & Stream Sniffer:
Effortlessly detects and captures hidden blob: URLs and fragmented MediaSource extensions (MSE) streams that ordinary downloaders miss.

• Durable Resume Engine:
Incremental local writing ensures that if your Wi-Fi drops or your browser restarts, your download picks up right where it left off instead of starting from scratch.

• "Capture While Playing" Fallback:
When media URLs are heavily obfuscated or inaccessible, VidNeatDown’s built-in playback capture records visible, non-DRM streams directly from the video player buffer.

• Full-Featured Download Queue Manager:
Pause, resume, restart, cancel, reorder downloads, and choose your preferred resolution (1080p, 720p, 480p, or best available).



VidNeatDown includes built-in specialized extractors for popular platforms and thousands of standard HTML5 web players:
• Vimeo: Downloads hosted and embedded Vimeo videos in full HD with merged audio and video tracks.
• Twitter / X: Easily save high-resolution MP4 videos and GIFs from timelines, threads, and cards.
• Facebook: Download Facebook Reels, stories, and feed videos directly.
• Reddit: Automatically muxes Reddit’s separate video and audio DASH streams into complete MP4 files with sound.
• Bilibili: Enhanced support for multi-resolution video and audio extraction.
• Generic Embedded Players: Universal sniffer works seamlessly across thousands of streaming sites and custom web players.

1. Navigate to any website containing a video you wish to save.
2. Play the video for 2–3 seconds to allow the stream to initialize.
3. Click the VidNeatDown extension icon in your toolbar or sidebar.
4. Select your preferred resolution (e.g., 1080p, 720p, Original) and click Download.
5. VidNeatDown fetches the segments, remuxes the audio/video into an MP4, and saves it directly to your downloads folder.

Unlike other video downloaders that upload your links to remote servers:
• Zero Server Processing: 100% of segment fetching, remuxing, and file assembly happens locally inside your Firefox browser sandbox.
• No Companion App Needed: Works entirely out of the box without installing external executable files or desktop software.
• No Tracking or Telemetry: VidNeatDown does not track your browsing habits, collect personal data, or inject advertisements.



• DRM Protected Content: In compliance with store guidelines, encrypted or DRM-protected video streams (such as Netflix, Amazon Prime, Disney+, or Widevine/PlayReady protected media) cannot and will not be downloaded.
• Store Policy Compliance: This add-on adheres strictly to Mozilla Add-on Policies and does not support downloading from services where prohibited by law or platform terms of service.
