[Book Correction And Common Errors](https://help.publishdrive.com/book-upload-and-correction?hsLang=en#book-correction-and-common-errors) # Image is too large: can't be larger than 5.6 megapixels No images inside the ebook can be larger than **5.6 megapixels**. The total pixel size is calculated by multiplying the length and the width of a picture. For example, if you have an image that is 2,000 pixels tall and 2,000 pixels wide, that is 4 million pixels (2,000 x 2,000) or 4 megapixels (1 million pixels = 1 megapixel). The same is true for the embedded cover as well. The embedded cover is the one that is "inside" your book, in the EPUB file. If someone buys the book, the embedded cover will be displayed on the virtual bookshelf of the reader. Because most people read books on a smartphone or e-reader, there is a maximum size limit in many bookstores (like Apple Books) set: **5.6 megapixels** (otherwise books would occupy too much space on the user's device). ![](https://help.publishdrive.com/hs-fs/hubfs/inline34267595-png.png?width=328&height=420&name=inline34267595-png.png) ### Fix it using Calibre 1\.
