Frequently Asked Questions

What size should a YouTube thumbnail be?

YouTube custom thumbnails display at 1280×720 pixels (the widely-used recommended size from Google Ads specs; YouTube's help page recommends up to 3840×2160 with a 640px minimum width) with a 16:9 aspect ratio. The minimum width is 640 pixels. Upload any size photo and this tool will automatically resize and crop it to the perfect YouTube thumbnail dimensions.

Why does YouTube require 16:9 for thumbnails?

YouTube recommends the 16:9 aspect ratio for custom thumbnails — other ratios may be letterboxed or display differently. This tool crops your photo to exactly 16:9 so it always meets YouTube's recommendation.

What file format is best for YouTube thumbnails?

JPEG offers the best quality-to-size balance and is the recommended format. PNG is only needed if your thumbnail uses transparency. YouTube also accepts GIF and PNG, but JPEG produces the smallest files with no visible quality loss.

Will my photo metadata be removed?

Yes. All EXIF metadata including GPS location, camera model, and timestamp are automatically stripped from your output thumbnail. Your processed image contains only the visual data.
