Build a consistent 16:9 thumbnail
This preset uses a 1280×720 pixel canvas and a 16:9 aspect ratio. It works best with landscape artwork already composed for a widescreen frame.
A resize changes dimensions, not composition. Crop a portrait or square source before resizing when the subject needs to stay large and centered.
Useful for
- Standardize episode or tutorial artwork at 1280×720 pixels.
- Resize a video still before adding it as a thumbnail.
- Prepare matching 16:9 images for a series or playlist.
Resize tips
Check small-scale clarity
Preview the downloaded image at a smaller size to confirm the main subject and any text remain easy to recognize.
Use a 16:9 source
Starting with a widescreen crop reduces the chance that important content will be cut off or stretched.
