Free tools · THUMBNAILS
Paste a YouTube link and save its thumbnail in every size YouTube keeps.
Images load from YouTube’s own servers; nothing you paste reaches VidMyth. Thumbnails belong to their creators — use them for reference, or make your own.
This YouTube thumbnail downloader saves the thumbnail of any public YouTube video or Short. Paste the link, and every size YouTube keeps for that video appears — the full-size image where the video has one, then the smaller versions YouTube uses around the site. Press Download and the image saves to your device.
It runs entirely in your browser. The images load straight from YouTube's own image servers, nothing is uploaded to VidMyth, and there is no account, limit or watermark.
● HOW IT WORKS
Paste a YouTube link — a watch link, a youtu.be link, a Shorts link — or the video's ID.
Every size YouTube keeps for that video appears, from the full-size image down.
Press Download on the size you want; the image saves straight from YouTube to your device.
Free, with no sign-up. It runs in your browser; nothing you paste or upload is sent to VidMyth or stored. Next: Make your own thumbnail.
YouTube keeps several copies of every thumbnail. The largest, up to 1280 × 720, exists for videos uploaded in HD; when a video doesn't have it, the tool says so and offers the next size down. Standard (640 × 480), high (480 × 360) and medium (320 × 180) versions exist for practically every video.
The 4:3 sizes (640 × 480 and 480 × 360) are letterboxed copies of a 16:9 thumbnail, so they show dark bars above and below the picture. For the clean 16:9 image, take the largest size available.
Studying what works in your niche is the most common use: save the thumbnails of the videos you are competing with, line them up, and look for what they share — the text length, the faces, the colours, the composition. Recovering your own thumbnail when the original file is lost is another; so is putting a video's image into notes, a presentation or a review of your channel.
Thumbnails belong to the people who made them. Use other creators' images for reference and research, not as your own thumbnails, and ask before republishing one. When you need a new image, the YouTube thumbnail maker designs one for your own video, and the thumbnail size guide covers the rules for uploading it.
Every YouTube video has an 11-character ID — the part after v= in a watch link, after youtu.be/ in a short link, or after /shorts/ in a Shorts link. The downloader reads the ID from whatever you paste, so you don't have to find it yourself, and it ignores the rest of the link: timestamps, playlist IDs and tracking parameters make no difference.
YouTube serves each video's thumbnails from its own image servers at fixed addresses built from that ID. The downloader shows the sizes straight from there and saves the one you choose as a JPG named after the video, so you can tell your downloads apart later.
Paste a Shorts link and the downloader finds the Short's thumbnail the same way. For a Short of your own, YouTube now lets verified channels upload a custom Shorts thumbnail, recommending 2160 × 3840 in 9:16; the thumbnail resizer makes one from any image.
● QUESTIONS
Paste the video's link into the downloader above, choose the size you want and press Download. The image saves straight to your device; there is nothing to install and no account to make.
Yes. Paste the Shorts link (youtube.com/shorts/…) and the downloader shows the Short's thumbnail in every size YouTube keeps for it.
YouTube only keeps the 1280 × 720 version for videos uploaded in HD. When it doesn't exist, the downloader says so and the next size down — 640 × 480 — is the best available.
Saving a thumbnail to study it is common practice, but the image still belongs to its creator. Don't reuse another channel's thumbnail as your own, and ask permission before republishing it.
No. The tool runs in your browser and loads the images directly from YouTube's image servers; nothing you paste is sent to or stored by VidMyth.
● KEEP GOING
A YouTube thumbnail maker that plans before it draws: three ideas in three formats, then a spelling-checked 1280x720 image from each one you pick.
The recommended YouTube thumbnail size is 3840 × 2160 pixels for a video and 2160 × 3840 for a Short, in 16:9 and 9:16.
Resize any image to a YouTube thumbnail — 16:9 or 9:16, under the size limit — in your browser.
Paste a script and see how long it runs when read aloud — and whether it fits a Short.
Find the width or height for any ratio — 16:9, 9:16, 1:1, 4:5 — or the ratio of any size.
