YouTube Thumbnail Scraper

YouTube Thumbnail Scraper extracts every video thumbnail visible on the YouTube page you're currently viewing — search results, channel uploads, playlists, home feed, trending, subscriptions, or hashtag pages. Export the thumbnails as JPG files and the metadata as a clean CSV. No API key. No login. No tracking. WHY YOU'D USE IT • Content creators studying competitor thumbnail design • Marketers running thumbnail A/B research • Designers building mood boards from top performers in a niche • Analysts pulling video metadata into spreadsheets • Anyone tired of right-click → save-image → repeat 100 times WHAT IT EXPORTS For every video on the page, you get: • Video ID • Title • Channel name • Duration • View count • Publish date • Direct video URL • Thumbnail URL (at your chosen quality) • Live thumbnail URL from the page THUMBNAIL QUALITY OPTIONS • Max resolution (1280×720) — for design work • SD (640×480) • HQ (480×360) — universal fallback • MQ (320×180) • Default (120×90) KEY FEATURES • One-click bulk JPG download — saves to a named folder under Downloads • CSV export for spreadsheet analysis • Auto-scroll to load every lazy-rendered video tile • Configurable scroll passes (1–100) for long channel feeds • Per-tab session memory — accidentally close the popup, reopen, results are still there • Auto-clear when you navigate to a new page (no stale data) • Manual Clear Cache button • Skips hidden tiles cached by YouTube's single-page-app routing • Works on Search, Channel, Playlist, Home, Trending, Subscriptions, Shorts, Hashtag pages • Works on www.youtube.com and m.youtube.com PRIVACY • No accounts, no signups, no analytics • No data leaves your browser except the direct download requests to i.ytimg.com (YouTube's public thumbnail CDN) • Open source — inspect every line of code • Permissions limited to youtube.com and the thumbnail CDN HOW IT WORKS 1. Open any YouTube page with videos 2. Click the extension icon 3. Choose thumbnail quality + scroll passes 4. Click "Scrape Page" 5. Click "Export CSV" or "Download Thumbnails" 6. Files land in ~/Downloads/<page-title>/ LIMITATIONS • Thumbnails come from YouTube's public CDN. If a video doesn't have a max-resolution version, the extension falls back to HQ automatically. • Chrome rate-limits batch downloads. For huge channels (500+ videos), download in chunks. • Respects YouTube — does not bypass private videos, paywalls, or age gates. Only sees what your browser already sees. This extension is for personal research and analysis. Respect copyright when reusing thumbnails.
