Download thumbnails, transcripts and comments from any YouTube video — plus bulk transcripts from playlists or a whole channel. One extension, free, no data collected.
+ Add to Chrome — FreeFrom the small 120×90 preview up to the full-HD 1280×720 maxres image — see which sizes exist for the video and grab the one you need.
This is a 3-in-1 downloader: thumbnails, the full transcript (TXT, SRT, Markdown) and the comment thread (CSV or text) all download from the watch page you are already on.
Point it at a playlist, your Watch Later or a whole channel page and it collects the transcripts one by one into a single download.
Studying what the winning thumbnails in your niche do — composition, faces, text weight — is how packaging improves. Save references into a folder and study them side by side.
Everything is read from YouTube in your own browser and goes to your downloads folder. The extension has no account, no tracking and no servers of its own.
Whatever YouTube has generated for that video — typically 120×90, 320×180, 480×360, 640×480 and, when available, the 1280×720 maxres version. The extension shows only sizes that actually exist.
No — thumbnails are the creator's work and re-using one on your own upload is a copyright problem. Download them to study, reference and learn from. Make your own better one.
Yes — one extension, three downloaders. Transcripts export as plain text, SRT subtitles or Markdown (timestamps optional); comments export as CSV or text, replies included. Playlists and channel pages can be harvested in bulk.
Yes — Shorts have thumbnails, captions and comments too, and the extension finds them the same way.
A thumbnail earns its keep in click-through rate. VideoCore's free video diagnosis reads a video's real performance and tells you whether packaging is the bottleneck.
Real analytics, script decoding, idea mining and revenue attribution for your channel — built on measured data, never generic guesses. The core tools are free to try.
