Once you've uploaded your eBook, you may want to make changes to the file. KDP compresses your eBook content file into a ZIP file that contains an HTML file of your text content, as well as any included images. You can download and unzip the ZIP file, edit the HTML file, then re-zip and re-upload the book content file.

Make sure the HTML file and included images are in a single folder in the ZIP file, without any content in sub-folders. We recommend opening your HTML file in Word to make changes. If you have extensive HTML knowledge, you can also modify the HTML file using an HTML editor of your choice.
