WHAT IS THUMB LAB
A darkroom for YouTube thumbnails
Every YouTube video is stored with five official thumbnail sizes, but YouTube only ever shows you one at a time. Thumb Lab reads the video ID out of any link and lines up all five sizes side by side, like frames on a contact sheet, so you can compare them and save the one you need without digging through page source or browser dev tools.
WHO IT'S FOR
Built for people who study thumbnails
Creators pull competitor thumbnails to study composition and color before designing their own. Editors grab a high-res still to reuse in a video preview. Students and researchers save frames for presentations. Thumb Lab keeps this fast and local — nothing you paste is sent anywhere except a direct request to YouTube's own image servers.

REFERENCE
YouTube thumbnail resolutions explained
YouTube generates the same five file names for every upload. Not every video has the largest one — Thumb Lab checks for you and drops any size that doesn't exist.
| FILE | SIZE | DIMENSIONS | TYPICAL USE |
|---|---|---|---|
| maxresdefault.jpg | Master | 1280 × 720 | Full HD reuse, print checks, thumbnail teardown |

FAQ
Frequently asked questions
Is it free to download YouTube thumbnails with Thumb Lab? ⌄
Yes. Thumb Lab is free, requires no sign-up, and runs entirely in your browser.
What's the highest resolution I can get? ⌄
Most videos have a 1280×720 master image. If a channel hasn't uploaded one, Thumb Lab automatically removes it from the sheet and shows the next largest size available.
Does it work with YouTube Shorts? ⌄
Yes. Paste any youtube.com/shorts/ link and Thumb Lab pulls the same five sizes as a regular video.
Do I need to install anything? ⌄
No. It works directly in your browser tab and no images are uploaded to a server — everything happens client-side.
Is it legal to download YouTube thumbnails? ⌄
Thumbnails carry the same copyright as the video they belong to. Saving one for reference, moodboards, or personal analysis is generally fine, but reusing someone else's thumbnail in your own published content without permission isn't advisable.
