CodeKitHubWhat Is This Tool?
A thumbnail grabber turns a video URL into a direct link to that video's cover image, in whichever resolutions the platform has actually generated for it. For YouTube this works because thumbnails live at predictable, publicly documented URLs on YouTube's own CDN (img.youtube.com) — the tool builds those URLs from the video ID and checks which sizes exist, from the small default preview up to 1280×720 maxresdefault where available.
Vimeo doesn't publish a predictable thumbnail URL pattern, so the tool instead calls Vimeo's public oEmbed endpoint (the same mechanism sites use to embed a Vimeo player from just a URL), which returns the video's official thumbnail. No API key or login is required for either platform.
Why Use It?
- Get the actual highest resolution available — not every video has a maxresdefault (1280×720) thumbnail; the tool checks each size and only shows the ones that really exist, instead of linking a broken image.
- Works for both YouTube and Vimeo from the same input box — paste any recognizable video URL and it's detected automatically.
- Nothing is uploaded: the video URL is parsed locally and the thumbnail is fetched directly from the platform's own servers.
- One-click download for every available size, useful for blog covers, video previews, thumbnails in a CMS, or quick reference images.
- Free, instant and requires no account on YouTube, Vimeo or this site.
How to Use
- Copy a YouTube or Vimeo video URL (a full watch link, a youtu.be short link, or a Vimeo video link all work).
- Paste it into the input box and click "Get thumbnail" (or press Enter).
- A preview of the largest available thumbnail appears, with every resolution that actually exists for that video listed below it.
- Click any size to download it directly.
Example
Input
https://www.youtube.com/watch?v=dQw4w9WgXcQOutput
Max resolution (1280×720), Standard definition (640×480), High quality (480×360), Medium quality (320×180), Default (120×90)Not every video has every size — very old or low-resolution uploads may not have a maxresdefault thumbnail. The tool only lists sizes it confirmed actually exist for that specific video.
YouTube thumbnail sizes explained

|---|---|---|
| maxresdefault | 1280×720 | Only exists for videos uploaded in HD |
| sddefault | 640×480 | Standard definition, widely available |
| hqdefault | 480×360 | Almost always available |
| mqdefault | 320×180 | Medium quality |
| default | 120×90 | Always available — the smallest fallback |
Frequently Asked Questions
Why doesn't this video have a maxresdefault (largest) thumbnail?
YouTube only generates the 1280×720 maxresdefault thumbnail for videos uploaded in HD. Older videos, low-resolution uploads, or some auto-generated content may only have the smaller sddefault, hqdefault, mqdefault or default sizes. The tool checks each size individually and only lists the ones that actually load, so you won't get a broken image.
Does this work on private or unlisted videos?
No. Both YouTube's thumbnail CDN and Vimeo's oEmbed endpoint only return data for videos that are publicly viewable. Private videos, and in some cases age-restricted or region-blocked videos, won't return a thumbnail.
Is the video itself downloaded or uploaded anywhere?
No — only the thumbnail image, and only from the platform's own public servers. The tool never downloads, re-hosts or processes the video itself, and the URL you paste is never sent to any server other than YouTube's or Vimeo's.
Can I use these thumbnails for my own content?
Video thumbnails are typically copyrighted by the video's creator or the platform, the same as any other image on the video. This tool is meant for legitimate uses like previewing a link before sharing it, archiving a reference image, or building an embed with your own player — not for republishing someone else's thumbnail as your own content without permission.
What URL formats are supported?
Any recognizable YouTube link works — full watch URLs (youtube.com/watch?v=...), short youtu.be links, Shorts links, and embed URLs. For Vimeo, standard vimeo.com/VIDEO_ID links work. Paste the whole URL; the tool extracts the video ID automatically.
Do I need to install anything or sign up?
No. It runs entirely in your browser as a web page — no extension, no app, no account. Paste a URL and the thumbnail appears within a second or two.
Why is the image I get lower resolution than I expected?
The tool can only serve the sizes YouTube or Vimeo actually generated for that specific video. If a video wasn't uploaded in HD, YouTube never creates a maxresdefault (1280×720) version, so the largest real option might be 640×480 or smaller — that's a limitation of the source video, not of this tool.
Can I grab a thumbnail from a YouTube Shorts video?
Yes — Shorts URLs (youtube.com/shorts/VIDEO_ID) are recognized the same way as regular watch links, and the same set of thumbnail sizes is checked.
Does this download the video file itself?
No. This tool only ever fetches the static cover image, not the video. There's no video downloading functionality here at all — for that you'd need a dedicated video downloader, which is a separate category of tool with its own copyright considerations.
Is there a limit to how many thumbnails I can download?
No limit and no rate-limiting beyond what YouTube's or Vimeo's own public servers might impose. You can paste as many URLs as you want, one after another.
Why does the thumbnail look cropped or padded compared to the video itself?
YouTube and Vimeo generate thumbnails at a fixed aspect ratio, usually 16:9. If the source video itself has a different aspect ratio (like a vertical Short), the platform crops or pads the frame when creating the thumbnail — this happens on the platform's side before the image ever reaches this tool.
