Install. Pin. Start watching.

The current release supports Chrome and Microsoft Edge on macOS. The extension is distributed as a direct ZIP package, rather than a browser-store listing.

1. Add the extension

Download the extension ZIP and unzip it.
Open chrome://extensions (or edge://extensions).
Enable Developer mode, click Load unpacked, and select the unzipped extension folder.
Pin PremiumVideoDownloader from your browser’s extensions menu.
Open the extension and click Enable video capture. Review the browser’s site access request.
Play a video, then open the extension to see detected sources.

Existing browser tabs may need a reload after installation. Video streams generally appear after playback starts. A browser-generated blob URL is not itself a downloadable media file; the extension looks for the underlying network source.

2. Install the local stream helper

MP4 and other direct file downloads work without it. HLS/DASH processing, separate audio/video merging and stream quality options use the local helper.

Download and unzip the macOS helper.
Install Python 3, yt-dlp and FFmpeg if not already installed. With Homebrew:

brew install python yt-dlp ffmpeg

In Terminal, enter the unzipped companion folder and run:

python3 install.py --browser chrome
# For Edge instead:
python3 install.py --browser edge

The installer registers this app only for your own browser account. It does not require an administrator password. Then open the extension → Settings → Connect helper.

3. Activate Premium

Choose a $6 monthly or $23 lifetime license. Payments are USDC or SOL on Solana. Send your transaction signature to support for manual verification. Sign in with the email account upgraded by support. On a new device, sign in with the same email and password, then choose Restore purchase. Lifetime Premium does not require another payment.

If no video appears

Check that site access has been enabled.
Play the video, then click the rescan button.
Reload a tab that was open before you installed the extension.
For expired media links, play the video again and capture a fresh source.
Browser-internal pages and encrypted DRM content are not supported.

Uninstall

Remove the extension from your browser’s extensions page. To remove only the helper registration, run python3 install.py --browser chrome --uninstall. Downloaded files and saved settings are preserved.
