Kindle Direct Publishing lets you upload and convert your final draft from several formats. For best results, we recommend that you upload in DOC (.doc or .docx) or PRC (.prc) format. Be sure to read through the format you are using to upload below prior to publishing your work with KDP.
To learn more about the recommended PRC format, we suggest reading through our Simplified Guide to Building a Kindle Book. This guide walks you through editing a .doc in word, saving the file in a format accepted using Mobipocket Creator, and converting for optimum usability with KDP.
We accept the following formats:
- Word (.doc/.docx, or DOC/DOCX)
- ePub (.epub, or EPUB)
- Plain Text (.txt, or TXT)
- MobiPocket (.mobi, or MOBI and .prc, or PRC)
- Zipped HTML (.zip, or ZIP)
- Adobe PDF (.pdf, or PDF)
Word (.doc/.docx, or DOC/DOCX)
Kindle Direct Publishing accepts most DOC files for eBook conversion; however, some DOC files which contain complex formatting may not export well. Be sure to use the inline previewer to check your files conversion if it contains tables or is graphic intensive to ensure conversion was successful. To troubleshoot any conversion errors, we suggest reviewing our Simplified Guide to Building a Kindle Book.
Kindle content is re-flowable and can be viewed with different font sizes. For this reason, page numbers, font sizes and margins set in Word do not apply. The "Page Break" feature in Word should be used to create intentional page breaks (i.e. ending a chapter for a smoother transition and better reading experience).
Images can be added using the 'Insert' function in Word to create interest within your eBook. Do not use the copy/paste function.
If you're submitting your file in DOC format, the entire book text should be uploaded in one DOC file, including your cover file.
ePub (.epub, or EPUB)
KDP converts unzipped EPUB files.
Plain Text (.txt, or TXT)
KDP converts all text to HTML. Image locations referenced in the TXT file will not result in an image displaying in the eBook after conversion. For this reason, TXT files should only be used when your book file does not contain images.
Mobipocket (.mobi, or MOBI and .prc, or PRC)
KDP handles MOBI file formatting and images very well. For more information about the Mobipocket format and the Mobipocket Creator, please visit the Mobipocket Creator homepage.
Important: Only unencrypted MOBI files are supported. Also, if your book file is not in one of the formats listed here, use the "Save As…" or "Export" function in the program you used to create the file to export the contents into HTML format.
Zipped HTML (.zip, or ZIP)
If your HTML file contains images or multiple files, please compress all files into a .zip file before uploading.
For help with HTML please see our Basic HTML Formatting Guidelines.
The following pages provide information for advanced HTML formatting.
• Supported HTML Tags
• Custom HTML Tags Supported
Important: All the files in the ZIP archive must be in a single folder, without any files in subfolders (such as image files). Save your details in the web browser using the "Save As Web Page (Complete)" option or similar, which will include any images on the page. Then the resulting files can be put inside a ZIP file.
Adobe PDF (.pdf, or PDF)
While the Kindle Direct Publishing accepts Portable Document Format (PDF) files for eBook conversion, PDF files contain special formatting and/or images which may not export well in the conversion process. It is difficult for optical character recognition systems like our KDP converter to interpret the embedded formatting and image placement.
We've had publishers report numerous formatting and conversion issues when uploading PDF files, such as irregularly bolded text, irregular page breaks, inconsistent font sizes, inconsistent text flow, and missing or oversized images. For this reason, we recommend converting your PDF to DOC format and following our Simplified Guide to Building a Kindle Book.
