Frequently asked questions
What size is a Bluesky banner?
3000 x 1000 pixels, a 3:1 strip. Avatars look sharp at 1000 x 1000.
What is the difference between fill and fit?
Fill crops your image to the exact shape, keeping the part you choose. Fit keeps the whole image and adds a background color around it.
Is my text or image uploaded anywhere?
