How this thumbnail downloader works
Every public YouTube video has a set of preview images stored on YouTube's image server, i.ytimg.com. They sit at predictable addresses built from the video's 11-character ID, such as https://i.ytimg.com/vi/VIDEO_ID/hqdefault.jpg. When you paste a link, this page does three things in your browser:
- Finds the video ID. It reads the ID from any common link format:
youtube.com/watch?v=,youtu.be/,youtube.com/shorts/,/embed/and/live/links, or a bare ID. - Asks YouTube for each standard size. It loads the five standard file names (listed in the table below) directly from YouTube.
- Checks what actually came back. If YouTube hasn't made a particular size for that video, it sends a small 120 × 90 grey placeholder instead of the real image. The tool measures every image as it arrives and marks those sizes as Not available, so you don't download a grey box by mistake.
Nothing you paste is sent to our server or stored. The only outside requests are the image requests your browser makes to YouTube's image server, the same requests it makes when you browse YouTube.
Thumbnail sizes YouTube provides
These are the standard files the tool checks. The pixel sizes are what YouTube's image server returned when we checked 11 different videos, including Shorts, in October 2026. The two 4:3 sizes usually contain black bars above and below a 16:9 picture.
| Label in the tool | File name | Size (px) | Shape | Always there? |
|---|---|---|---|---|
| Maximum resolution | maxresdefault.jpg | 1280 × 720 | 16:9 | No: missing for many older or low-resolution uploads |
| Standard definition | sddefault.jpg | 640 × 480 | 4:3 (letterboxed) | No: missing for some videos |
| High quality | hqdefault.jpg | 480 × 360 | 4:3 (letterboxed) | Normally yes |
| Medium quality | mqdefault.jpg | 320 × 180 | 16:9 | Normally yes |
| Default | default.jpg | 120 × 90 | 4:3 | Normally yes |
For most purposes, pick the largest size that shows as available. If you need a clean 16:9 image without black bars and the maximum size is missing, the 320 × 180 medium image is the only other 16:9 file, but it is small. Cropping the bars off the 480 × 360 image gives you a 16:9 picture of roughly 480 × 270.
What to do when the maximum size is missing
A missing maxresdefault.jpg is the most common surprise. It doesn't mean the tool is broken. YouTube simply hasn't created that file for the video. In our testing it is usually missing for videos uploaded in low resolution. YouTube's very first upload, "Me at the zoo" (ID jNQXAC9IVRw), only has the three smaller sizes. A few things to try:
- Use the next size down. "Standard definition" (640 × 480) or "High quality" (480 × 360) is often good enough for a reference or a blog preview.
- Wait if the video is brand new. Images for a video that is still processing may appear later.
- Ask the creator. If you have permission to use the thumbnail, the creator can send you the original artwork. YouTube recommends uploading custom thumbnails at up to 3840 × 2160, so the creator's original file is likely to be much sharper than any copy on the image server.
We explain the reasons in more detail in why maxresdefault.jpg is missing for some videos.
Saving the image
The Download button fetches the image and saves it as a file named after the video ID and size, for example jNQXAC9IVRw-hqdefault.jpg. If your browser or a privacy extension blocks that, the image opens in a new tab instead. Right-click it (or long-press on a phone) and choose Save image. Open shows the image in a new tab, and Copy link copies its address so you can paste it elsewhere.
Before you reuse a thumbnail
Being able to download a thumbnail doesn't give you the right to reuse it. A custom thumbnail is artwork made by the video's creator, and it is normally protected by copyright. Downloading one to study it, or for your own private reference, is very different from putting it on your own website, in a video or in an advert. YouTube's Terms of Service also restrict copying content except as the service allows, with the rights holder's permission, or as the law allows. If you plan to publish someone else's thumbnail, get their permission. Read our plain-English guide to using YouTube thumbnails legally first (it isn't legal advice).
Common questions
Is this tool free?
Yes. There's no sign-up and no download limit. The site is supported by advertising.
Does it work for YouTube Shorts?
Yes. Paste the Shorts link (youtube.com/shorts/…) and the tool reads the ID. The standard image files are landscape even for Shorts. In the Shorts we checked, the 1280 × 720 image had the vertical picture in the middle and a blurred copy of it filling the sides.
Why do some sizes say "Not available"?
YouTube only creates some sizes for some videos. When a size doesn't exist, YouTube returns a 120 × 90 grey placeholder. The tool detects that placeholder and labels the size as not available rather than showing it.
Can I get the thumbnail of a private or deleted video?
Usually not. If YouTube returns nothing but placeholders, the tool tells you no thumbnails were found. That normally means the video is private or deleted, or the ID is mistyped.
Do you keep a record of the links I paste?
No. The link is processed in your browser and isn't sent to our server. See our privacy policy for details.
