# How to Download a YouTube Thumbnail in Every Size Source: https://devanasolver.github.io/youtube-creator-toolkit/blog/how-to-download-youtube-thumbnails/ Published: 2026-10-02 | Updated: 2026-10-18 | Site: Creator Toolkit (free YouTube creator tools) Related free tool: Thumbnail Grabber - https://devanasolver.github.io/youtube-creator-toolkit/#thumbnails **TL;DR:** Paste a YouTube link into the Thumbnail Grabber and it lists every thumbnail size YouTube has for that video, from 320 x 180 up to the 1280 x 720 max resolution file, so you can save the one you need. If you are making your own, YouTube recommends 3840 x 2160 pixels in JPG or PNG with a 16:9 shape. Every public YouTube video has a thumbnail image stored in several sizes. You can save any of them without a screenshot. The Creator Toolkit [Thumbnail Grabber](https://devanasolver.github.io/youtube-creator-toolkit/#thumbnails) shows all of them for a link you paste, so you can pick the size you want and download it. ## What sizes does YouTube keep? YouTube stores a thumbnail for each video at a few fixed sizes. These are the ones the grabber lists: | Size name | Dimensions | Good for | | --- | --- | --- | | Max resolution | 1280 x 720 | Blog headers, presentations, reviewing a design | | Standard | 640 x 480 | Medium previews | | High | 480 x 360 | Small embeds | | Medium | 320 x 180 | Tiny previews and lists | The max resolution file does not exist for every video. If a video was uploaded in lower quality, or is very old, YouTube may only have the smaller sizes. The grabber shows what is available and hides what is not. ## How to download a YouTube thumbnail 1. Open the video on YouTube and copy the link from the address bar or the Share button. Watch links, youtu.be links, Shorts links, embed links and plain 11-character video IDs all work. 2. Paste it into the [Thumbnail Grabber](https://devanasolver.github.io/youtube-creator-toolkit/#thumbnails) and press **Get thumbnails**. 3. Pick the size you need. Open it in a new tab to check it, or use the download button. 4. If you plan to reuse the image, read the section below first. ## Can you reuse someone else's thumbnail? Downloading an image is easy. Having the right to use it is a separate question. A thumbnail is usually the creator's artwork, so copying it into your own video or post without permission can be a copyright problem. Good reasons to grab a thumbnail are research, a reference for your own design, or a screenshot for a review where you are allowed to show it. When in doubt, ask the creator. Also keep in mind that YouTube's [thumbnails policy](https://support.google.com/youtube/answer/9229980) does not allow a thumbnail that misleads viewers into thinking they will see something that is not in the video. That applies to the thumbnails you make too. ## What YouTube says about your own thumbnails Here is what YouTube's [custom thumbnail help page](https://support.google.com/youtube/answer/72431) recommends today: - A resolution of 3840 x 2160 pixels for videos (2160 x 3840 for Shorts), with a minimum width of 640 pixels for videos. - JPG or PNG files. - An aspect ratio of 16:9 for videos and 9:16 for Shorts. - File size limits that depend on the device. Uploads from a computer allow up to 50 MB. Mobile uploads for video thumbnails are limited to 2 MB. - Uploading a custom thumbnail needs a verified account. YouTube also says vertical videos that use a 16:9 custom thumbnail get an auto-generated 4:5 thumbnail on the home, explore and subscription pages. Your own thumbnail still shows in other places, such as the watch feed and on desktop. ## Tips for checking a thumbnail before you publish - Shrink it. Most viewers see your thumbnail at around the size of a postage stamp. If the text is not readable at 320 pixels wide, it is too small. - Test it against the competition. Put your thumbnail next to videos in the same topic. The [Thumbnail Preview and A/B Compare](https://devanasolver.github.io/youtube-creator-toolkit/#abtest) tool shows it in a mock feed. - Keep one idea per image. A face, an object and a few big words is plenty. - Match the promise to the video. A thumbnail that overpromises gets clicks and then people leave, and YouTube's own help says clickbait tends to produce low average view duration. ## Limits of the Thumbnail Grabber - It only reads public videos. Private and deleted videos have no public thumbnail. - It shows the thumbnail YouTube currently serves. If the creator changed it recently, you may see the old one for a short time. - It does not tell you which thumbnail performs better. Only YouTube Studio data can do that. ## FAQ ### How do I download a YouTube thumbnail? Copy the video link, paste it into the Thumbnail Grabber, press Get thumbnails and save the size you want. No sign-up is needed. ### What is the biggest YouTube thumbnail size I can download? For most videos it is the 1280 x 720 max resolution file. Some videos only have smaller sizes. ### What size should my own YouTube thumbnail be? YouTube recommends 3840 x 2160 pixels for videos with a 16:9 aspect ratio, and at least 640 pixels wide. Use JPG or PNG. On a computer the limit is 50 MB. ### Can I get the thumbnail from a Short? Yes. Paste the Shorts link. Shorts thumbnails are 9:16 when the creator uploaded a custom one, so the images can look different from long videos. ### Is it legal to use another creator's thumbnail? Downloading is not the problem, reusing is. A thumbnail is normally the creator's work, so ask for permission unless a specific exception applies. This is general information, not legal advice. ## Sources - https://support.google.com/youtube/answer/72431 - https://support.google.com/youtube/answer/9229980 --- From Creator Toolkit: https://devanasolver.github.io/youtube-creator-toolkit/
