VidPickr browser extension — one-click YouTube downloads, right from the page.

What the VidPickr extension does

On every YouTube watch page, the extension injects a small download button next to the video title. Clicking it opens a popup with the same format picker the website uses — every available resolution from 144p to 8K, audio- only options (M4A direct copy or MP3 at 320 kbps), and subtitle exports in SRT, VTT, or TXT. Pick a format, click download, and the file streams from YouTube’s CDN to your Downloads folder. No upload to any server, no queue, no “preparing your file” stall.

The extension uses the same in-browser muxing engine as the main web tool: WebCodecs to handle the stream, a fragmented MP4 muxer in JavaScript to combine video and audio, and the File System Access API to write directly to disk. The bytes you save are the same bytes YouTube serves to a browser playing the video — no transcoding, no quality loss, no fake-4K upscale.

Why use a YouTube downloader extension instead of a website?

Both work. The website is what you reach for when you download occasionally — paste a URL, click. The extension is what you reach for when downloading is part of a regular workflow: a podcast you save weekly, a creator whose videos you archive, a class you watch offline. Three concrete advantages:

• Zero copy-paste. The extension already knows what video you’re looking at. The button is in the page next to the title; one click and you have the format picker.
• Faster repeat downloads. Your default-quality preference persists between sessions, so the second click downloads the file directly without showing the picker.
• No new tab. The download happens inline with whatever you were doing on YouTube — picking the next video to watch, scrolling recommendations, reading comments.

Browser support

The extension targets the Chromium family of browsers, which covers most of the desktop browsing market in 2026. The install flow described above works identically across:

• Google Chrome — primary target, all features supported, chrome://extensions.
• Brave — same code path, Brave’s built-in tracking protection plays nicely with the extension, brave://extensions.
• Microsoft Edge — direct install supported now; Edge Add-ons store version pending Microsoft review (their YouTube-downloader policy is meaningfully less restrictive than Chrome’s).
• Opera, Vivaldi, Arc — Chromium-based; install identically.
• Firefox — Mozilla AMO submission pending. Firefox stable rejects unsigned extensions, so we cannot offer the direct-install fallback we have on Chromium browsers. Firefox users can use vidpickr.com directly until AMO approval lands.
• Safari — Apple requires Safari extensions to be Mac App Store apps wrapping the extension. We do not currently ship a Safari version; Safari users should use the website.
• Mobile browsers — extensions are not supported on Android Chrome or iOS Safari. Use vidpickr.com on iPhone or Android Chrome directly — the in-browser tool covers the same use cases.

Permissions and privacy

The extension declares two permissions in manifest.json:

• Host access for www.youtube.com and m.youtube.com — needed so the extension can read the video metadata on the page (title, available qualities) and inject the download button into the video header.
• storage API — saves your default-quality preference between sessions (e.g., “always pick 1080p MP4”).

The extension does not request access to: tab history, the broader web (no all_urls), the clipboard, the file system beyond the normal Downloads-folder scope, or any cookies outside the YouTube origin. The full manifest.json ships inside the zip — open it before installing if you want to verify what permissions are declared.

Architecturally, the privacy story is the same as the website: every byte flows YouTube CDN → your browser → your disk. Nothing about your downloads (URLs, filenames, formats, quantities) reaches our infrastructure. The extension makes no XHR or fetch calls to vidpickr.com domains during normal operation.

How updates work

Chromium disabled web-page-triggered extension updates in 2018, so off-store extensions like ours cannot auto-update. When we ship a new version we:

• Bump the file on this page (version number in the download button).
• Email Plus subscribers about meaningful changes.
• Show an in-extension banner pointing back here when a newer version is available.

Reinstalling takes the same 30 seconds as the first install. Your preferences (default quality, format) carry over because the extension storage API persists across reinstalls of the same extension ID.

Why this extension is not on the Chrome Web Store

The honest answer: Chrome Web Store policy 4.4 forbids extensions whose primary purpose is downloading from media-hosting sites that prohibit it in their terms — which covers every YouTube downloader. Long-running competitors have all been removed from the Web Store multiple times for this reason. Their current Chrome listings (when they exist) are usually disguised as generic “video helper” tools that do not name YouTube anywhere in the listing copy.

We could ship a watered-down store version that hides what it does. We would rather give you the real thing directly. The download you get from this page is the same code that would have been on the store had Google not prohibited it. Chrome itself still sandboxes the extension, restricts it to the permissions it declared, and quarantines anything misbehaving — the store gating was a discovery layer, not a security one.
