YouTube Video Downloader

Overview

The perfect tutorial, a lecture needed for class, or a music video for a flight. YouTube won't let you save any of it. Online converter sites are a minefield of pop-ups and fake download buttons. This extension skips all of that. Install it, browse YouTube normally, and a download button appears on every video. Click it, pick your quality (up to 4K when available), and the MP4 saves straight to your computer. It works on regular videos, Shorts, entire playlists, and YouTube players embedded on other websites.

The extension handles everything behind the scenes. It grabs the best available video and audio, combines them into a single ready-to-play file, and drops it in your downloads folder. Queue up to three downloads at once with live progress tracking, and they keep running in the background while you browse other tabs. Need a whole playlist? Queue every video and let it work through them one by one.

Everything stays private. Downloads happen locally on your device, nothing gets uploaded anywhere, and there's zero tracking or analytics. Try 3 free downloads to see how it works, no credit card needed.

Why It Exists

• Get ready-to-edit MP4 files by automatically merging YouTube's split adaptive audio and video streams.

How It Works

• Install the extension: Add YouTube Downloader to Chrome, Edge, Brave, or Opera and activate your license. The extension integrates directly into YouTube pages.
• Browse YouTube normally: Navigate to any watch page, Shorts feed, playlist, or embedded player. The extension detects playable content and decrypts the adaptive stream URLs automatically.
• Pick your quality and download: Click the download button to see every available resolution with file-size estimates. Select your preferred quality and the extension fetches, merges, and saves the final MP4.
• Edit or archive offline: Your finished MP4 or WebM file is ready in your downloads folder. Use it for editing, presentations, research, or offline viewing on any device.

Reviews

• Finally handles encrypted YouTube streams (5/5): We archive client livestreams and Shorts. This is the only tool that keeps up with YouTube's encryption changes and still hands back perfect MP4 files. - Caleb Whitford
• A must-have for creative briefs (4.9/5): The quality list and file-size estimates mean no surprises, and the three-download queue lets me prep assets for edits in one sitting. - Natasha Yuen
• Great for research teams (4.8/5): Embedded videos on partner portals used to be a pain. This extension detects them instantly and finishes the background conversion while we keep browsing. - Simon Greaves
