Frequently Asked Questions about YouTube Tools

Clear answers regarding file formats, privacy, performance, and usage limits.

What are the official dimension and file size requirements for YouTube thumbnails?
YouTube requires custom video thumbnails to be 1280 × 720 pixels (minimum width of 640 pixels) with a 16:9 aspect ratio and under 2 MB in file size. Supported formats are JPG, GIF, or PNG.
How does the duration badge safe-zone guide prevent obscured thumbnails?
YouTube overlays a black timestamp badge in the bottom-right corner of video thumbnails across mobile and desktop. Our thumbnail cropper displays this overlay during editing so key faces or text never get hidden.
What is the safe area for YouTube channel banners across TV, desktop, and mobile?
While the full banner canvas is 2560 × 1440 pixels (for smart TVs), the central text and logo safe area visible on all mobile phones and desktop browsers is 1232 × 338 pixels (or 1546 × 423 px depending on device scaling). Our banner tool marks this region clearly.
How do video chapter timestamps need to be formatted for YouTube descriptions?
The first timestamp must start at 00:00 (or 0:00), there must be at least three timestamps listed in ascending chronological order, and each chapter must be at least 10 seconds long.
