Frequently asked questions
Why does my thumbnail look blurry on YouTube?
Usually the source was smaller than 1280×720 and got upscaled, or heavy compression artifacts got amplified. Start from art at least 1280px wide and let this tool set the final size — it re-encodes at high quality within the 2MB budget.
What's the safe area for thumbnail text?
Keep text and faces away from the bottom-right corner, where the video duration badge overlays, and remember the thumbnail is often displayed tiny — bold, high-contrast elements at the center-left survive shrinking best.
Can I upload PNG thumbnails?
YouTube accepts PNG, but a 1280×720 PNG of a photo-style thumbnail can exceed 2MB. The JPG this tool produces stays well under the cap at visually identical quality.
