Frequently Asked Questions
Is 1280×720 required for all YouTube thumbnails?
Yes — YouTube recommends this exact 16:9 resolution for crisp thumbnail display across desktop, mobile and TV apps.
Will my image be cropped to fit 16:9?
Yes — it’s cropped to exactly fill 1280×720 rather than stretched, keeping proportions natural.
Can I add text overlays for my thumbnail with this tool?
No — this only resizes/crops to the correct dimensions; add text or graphic overlays in a separate editor before or after.
Does YouTube reject thumbnails that aren’t exactly this size?
YouTube does accept other sizes/ratios and will crop or pad them itself, but uploading at the exact 1280×720 recommended size avoids YouTube doing that cropping for you.
