Good to know
Choose a placement, then crop to fill or keep the whole image on a colored background. Presets describe output canvases; the publishing app can apply additional crops. JPG and PNG outputs are still images. Larger dimensions cannot restore missing detail.
What does the channel-banner guide show?
It marks the central area recommended for text and logos. The full banner has different crops on mobile, desktop, and TV. The guide is not included in the downloaded image.
Will my photo be stretched?
No. Cropping fills the selected shape without stretching. Keep the whole image fits it inside the canvas and fills any remaining space with your chosen background color.
Are these official required sizes?
Presets labeled Platform guidance follow the linked platform guidance. Suggested canvases are practical starting sizes, not official requirements. Check the placement preview before publishing, especially for ads.
