JB's Video Downloader
A private, on-device downloader for video and audio from 1000+ sites, powered by yt-dlp + ffmpeg. It runs as a tiny app on your own machine, so every download uses your connection and stays entirely on your device.
- Widest site support: YouTube, Vimeo, TikTok, X/Twitter and 1000+ more
- Any quality from 4K down to 144p, with live file-size estimates
- One-tap audio extraction to MP3 at 320 kbps
- Real-time speed, ETA and progress, streamed live
- Download history and running stats: items, data and duration
- No accounts, no cloud, no telemetry
Mac: ~117 MB notarized disk image, nothing to install. Windows/Linux: ~95 KB, needs Python once.
Unlike the Converter, which processes files right in your browser, a downloader has to fetch and stitch media in a real local process (browsers block this for security). That is exactly what keeps it private: the work happens on your machine, using your connection, and nothing is ever routed through a server of mine.
No terminal. Just double-click.
Unzip and open. It runs in your browser at localhost:9321. The Mac app is Apple-notarized with Python and ffmpeg built in; Windows and Linux use a one-time start file.
Mac
- Download and open the disk image, then drag JB Video Downloader into Applications.
- Open it from Applications. No prompts, nothing to install.
- Your browser opens with the app running. Quit anytime with the ⏻ Quit app button.
Signed and notarized by Apple, so there are no security warnings. Python and ffmpeg are built in, for Apple Silicon and Intel.
Windows & Linux
- Unzip, then double-click the start file for your system.
- First run sets up in about a minute (needs Python 3.9+; ffmpeg installs itself).
- Later runs start instantly.
Windows → Start - Windows.bat Linux → Start - Linux.sh
Windows shows a one-time "Run anyway" approval; the included READ ME FIRST file has the 10-second steps.
On first launch you accept a short personal-use agreement, and each download asks you to confirm you have the right to that content. This tool is intended only for lawful use: content you own, that is licensed for free download, that you have permission to download, or that is otherwise permitted in your jurisdiction.
