How to use YouTube Thumbnail Resizer
- Drop your imageDrop a photo or design on the box, or choose one. Previews for every size appear.
- Choose what stays in viewClick the part of the image that matters most; every crop is centred on it. Or choose Show it all for no cropping.
- DownloadUntick sizes you do not need, then download them all as a ZIP, or one at a time.
Drop an image and get a 1280 by 720 YouTube thumbnail, the 16:9 shape YouTube asks for and well over its 640-pixel minimum width, cropped around the part you click, together with a 2560 by 1440 channel banner. Save as JPG to stay well inside the upload size limit.
How it works
YouTube Thumbnail Resizer is a web page that does its work on your own device. The file you choose is opened by your browser, changed there and saved from there; it is never sent to a server, so there is no copy of it anywhere to delete, no queue and no waiting for an upload. Most online tools of this kind send your file to their servers and work on it there, and many keep it for a while. This one does not. There is no account, no watermark and no limit on how often you use it, and the result downloads the moment it is ready.
Keep the subject in the centre
Thumbnails appear small in search and suggestions, with the length of the video printed in the bottom right corner. Click a face or the main subject so it stays centred and clear of that corner.
Questions
What size should a YouTube thumbnail be?
16:9, at least 640 pixels wide, as YouTube's help says; 1280 by 720 is the size most creators use and what this tool makes.
