Questions
What size should a YouTube Thumbnail be?
YouTube Thumbnail uses 1280×720 pixels on this page. BunnyConverter loads that preset automatically so you can resize the uploaded image to the exact target dimensions in your browser.
Does BunnyConverter upload images when resizing for YouTube?
No. BunnyConverter resizes the selected image locally in your browser. The file stays on your device instead of being uploaded to a remote resize service.
Will resizing to 1280×720 change the image shape?
It can if the source image uses a different aspect ratio. This page keeps the exact 1280×720 target ready, but you may want to crop the image first if you need a cleaner fit without stretching.
