Growwly Labs Free · any video

Download any YouTube
thumbnail in full resolution.

Paste a video link and grab every size YouTube actually has for it, from the HD original down to the frames the algorithm auto-picked. No sign-up, no watermark, no upload limit.

Thumbnails belong to whoever uploaded the video. Use them for research and reference, not for reposting.

Under the hood

No upload, no queue,
no watermark.

Most thumbnail grabbers put a server between you and an image that was already public. This one just works out which sizes exist and hands you the files, which is why it returns in about a second.

  1. Step one

    Paste anything

    A full watch URL, a share link, a Shorts link, an embed URL, or the bare eleven character video ID. If there is a video ID somewhere in what you pasted, it will find it and ignore the rest.

  2. Step two

    Every size, checked

    Not every video has every resolution, and YouTube serves a grey placeholder rather than an error for the missing ones. Your browser loads each candidate and drops anything that comes back as a placeholder, so you only see real files.

  3. Step three

    Download the one you need

    Each card shows its true pixel dimensions so you can pick deliberately. You also get the four frames YouTube auto-generated from the timeline, which are often the most useful thing here if you are studying a competitor's packaging.

Frequently asked questions

Which resolutions can I get?
Up to 1280×720 for the maxres original, then 640×480, 480×360, 320×180 and 120×90, plus the four auto-generated timeline frames at 480×360. Whatever the video actually has is what you will see.
Why is the HD version missing sometimes?
Because it was never made. YouTube only generates the maxres file for some uploads, mostly older or lower-resolution ones, so there is nothing to fetch. Rather than hand you a grey placeholder, we leave it out.
Does it work with Shorts?
Yes. Shorts links, embed links, live URLs and youtu.be short links all work. Note that the stored thumbnail for a Short is still the standard landscape frame, not the vertical cover you see in the Shorts feed.
Can I use these thumbnails on my own videos?
No. The thumbnail belongs to whoever uploaded the video, and reposting one as your own is a copyright problem and usually a strike. Studying what makes a rival's packaging work, and then making your own version, is the legitimate use.
Do you store the videos or thumbnails?
No. The images load straight from YouTube's own image servers to your browser, and the download just passes the file through. There is no account, no history and nothing kept after you close the tab.
Is there a limit?
No. This one costs us almost nothing to run because there is no model and no analysis behind it, so there is no daily counter and no sign-in wall. Use it as much as you like.

Studying someone else's thumbnails?

The Thumbnail Agent does this properly: it tears down the thumbnails beating yours on click-through and tells you what to change about your own.
