To upload a cover for your book, open the Book Info section of your Dashboard and scroll down to the Cover Image section. Upload your cover image and scroll back to the top of the page to click Save. Note that the thumbnail preview of your cover image may not load the first time.
The cover image should conform to the following specifications:
- Dimensions: 2500px x 3750px
- Maximum size: 2 MB
- File format: JPEG or PNG
- Aspect ratio: 1:1.5
Your cover image will be used only on the web and ebook formats of the book. Covers for PDFs intended for print-on-demand purposes need to be prepared separately.
