Yes. The extension detects Shorts feeds, standard watch pages, and embedded players on third-party sites, then serves the same quality list in each case.
The downloader supports livestream replays, but it needs the on-demand version to exist first. Once the replay is posted it converts the HLS stream into a single MP4.
No. DRM-protected purchases remain off limits. The downloader only works on videos you can already view without digital rights management.
Up to three downloads can be active at once. Each item shows progress, speed, and an interrupt button so you can prioritise what matters.
For long conversions we recommend keeping the original tab open. That ensures the stream segments stay available until the MP4 is finalised.
Chrome and Chromium-based browsers like Edge, Brave, and Opera are supported. Make sure you're on an up-to-date build for Manifest V3 compatibility.
Writes the merged MP4 or WebM files directly to your downloads folder and tracks progress for simultaneous jobs.
Saves license activation, preferred quality settings, and queue history locally so everything persists between browser sessions.
Injects the downloader UI into the YouTube page you're viewing, including Shorts feeds and embedded players.
Monitors when you switch videos or open new players so the extension can refresh available quality options automatically.
Reads player configuration data to decrypt stream URLs, fetch manifests, and merge DASH or HLS segments into a final MP4.
Sends completion, error, and license prompts without forcing you to keep the popup open during longer conversions.
Adds a "Download with YouTube Downloader" option when you right-click embedded videos for quicker access.
Limits privileged access to youtube.com, youtu.be, and YouTube CDN domains required to capture and decrypt the streams.
YouTube is the world's largest video platform, hosting billions of videos from creators, educators, businesses, and entertainers. However, YouTube doesn't provide a built-in way to download videos for offline viewing—even for content you want to reference, archive, or watch without an internet connection.
YouTube Downloader solves this by seamlessly integrating with YouTube's watch pages, Shorts, and embedded players to give you instant access to high-quality MP4 and WebM files. Whether you're a content creator backing up your work, a researcher archiving educational content, or someone who wants to watch videos offline during travel, this extension makes it simple and reliable.
