1 Introduction
Kindle Previewer is a free desktop application that enables authors, publishers, and eBook service providers to preview
how their eBooks will appear when delivered to Kindle customers, and makes it easy to audit eBooks for different screen
sizes, display orientations, and font sizes. Kindle Previewer supports previewing your eBook with the latest typographic
and layout improvements that come with Enhanced Typesetting. Some of these improvements include higher quality
images, better table formatting and font alignments, smoother word spacing, hyphenation, kerning, and ligatures.
Kindle Previewer is designed to help authors, publishers, and eBook converters produce the highest-quality Kindle
eBooks. You can use the Kindle Previewer user interface to navigate through your eBook quickly and easily to confirm
that it is ready to be published to the Kindle Store and downloaded to Kindle devices and applications. To validate
multiple files, you can run Kindle Previewer from a command-line interface.
1.1 Quick Start
See sections 1.2 and 1.3 for system requirements and installation steps. Once you have successfully installed Kindle
Previewer, sections 1.1.1 through 1.1.3 provide examples of how you can preview eBooks with Kindle Previewer.
1.1.1 Opening Your eBook
To open your eBook, drag and drop the file into the dotted line box on Kindle Previewer (see Figure 1) or click File > Open
Book to select the file.
Your eBook should be in one of the following formats: .epub, .mobi, .htm, .html, .xhtml, .opf, .kpf, .doc, or .docx. Support
for .doc and .docx is currently limited to English-language content.
While your file is imported, Kindle Previewer displays a set of rotating screens that tell you more about the features.
When conversion finishes, thumbnail images of your eBook are displayed in the Thumbnail pane and an image of how
your eBook will look on a tablet device is displayed in the Previewer pane (see Figure 2).
Kindle Previewer User Guide
Amazon.com
page 6
Note: If you see a tablet device window and no thumbnails, it might be because your eBook is fixed-layout or does not
support Enhanced Typesetting (see section 2.1 for details).
In the Preview Options section, choose a device from the Device Type list and adjust the Font and Size to your
preference. Depending on your preference, you can collapse the Thumbnail, Previewer, or Preview and Navigation
Options panes from View > Window. See section 1.8.4 for more details.
1.1.2 Scanning through Your eBook
You can quickly scan through your eBook using the features of Kindle Previewer:
• Use the Thumbnail pane: o Scroll through the thumbnails to see how the overall layout of your eBook
appears to a Kindle customer.
o In the Preview Options section, use the Page Size slider to increase or decrease the size of the
thumbnails. This adjusts the size of the preview page and does not affect the actual content in any way.
o To get a full view of the thumbnails, set the Page Size slider in a position comfortable for you and close
the Previewer pane.
o To bring back the Previewer pane, click a thumbnail. o Use Auto-Advance View: Click the Auto-Advance
View button in the Navigation section. When you click the Auto-Advance View button, Kindle Previewer
navigates through your eBook automatically. You can pause, play, change speed, or click through pages
manually from this view.

1.1.3 Previewing Select Aspects of Your eBook
To preview select aspects of your eBook such as images, tables, links, lists, or drop caps, click the View All menu and
choose an option from the list (see Figure 3).
• Examples: If you choose Images, Kindle Previewer shows all pages with images in your eBook. If you choose
Drop Caps, Kindle Previewer shows all pages with drop caps in your eBook.
• You can scroll through these pages in the Thumbnail pane, click through them manually using the arrows in the
Previewer pane, or navigate through them automatically using Auto-Advance View.
• To search for pages with specific text, use Search at the top of Kindle Previewer and then use Auto-Advance
View to automatically preview all pages with the search results.
• To preview pages corresponding to a specific location, use the Location box in the Navigation section.
1.1.4 Validate Multiple Books with Kindle Previewer
To validate multiple files and get a summary of the validation status, errors, and warnings, you can run Kindle Previewer
from a command-line interface. If your book supports Enhanced Typesetting, you can use the generated output file (KPF)
to preview the book on Kindle Previewer user interface without having to reconvert the book. Run “kindlepreviewer –
help” from your command line interface to get started.
1.1.5 Run Quality Checks (Beta)
You can validate your book for quality issues such as broken links using the Run Quality Checks (Beta) option in the File
menu (see Figure 4). These checks are currently limited to external links, internal links (excluding table of contents), and
footnotes.

1.5 Supported Languages

(Simplified), Cornish, Corsican, Danish, Dutch, Eastern Frisian, English, Finnish, French, Frisian, Galician, German,
Icelandic, Irish, Italian, Japanese, Luxembourgish, Manx, Northern Frisian, Norwegian, Nynorsk Norwegian, Portuguese,
Provencal, Romansh, Scots, Scottish Gaelic, Spanish, Swedish, Welsh, and the Indian languages Malayalam, Tamil, Hindi,

1.6 Importing and Exporting Files
1.6.1 Supported Import File Formats
Kindle Previewer can display eBooks created in the following file formats:
• .kpf
• .mobi • .azw
• .epub
• .htm
• .html
• .xhtml
• .opf
• .prc
• .azw3

Kindle Previewer User Guide
Amazon.com
• .docx*
Note: Support for this file format is currently limited to English-language content.
Kindle Previewer User Guide

1.6.2 Supported Export File Formats
Kindle Previewer can export eBooks to the following file formats:
• KPF: You can use this file to open your book on Kindle Previewer the next time you want to preview without
reconverting it.
• MOBI: You can use this file to sideload to older Kindle reading applications or devices that don’t support
Enhanced Typesetting.
• AZK: You can use this file to sideload to older iOS devices that don’t support Enhanced Typesetting.
You can’t sideload a KPF file to a device. If your eBook supports Enhanced Typesetting, sideloading a MOBI or AZK file to
the latest devices won’t give an accurate preview of those layout and typographic improvements. You can use Kindle
Previewer to confirm that your eBook supports Enhanced Typesetting (see section 2.1).
Note: If you are unable to export or the export option is disabled, it might be due to the following reasons:
• If you’re previewing a KPF file, the export option is disabled. If you used Kindle Create to generate the KPF file,
you can directly upload it to Amazon for publishing. If you used Kindle Previewer to generate the KPF file, you
can use it to open your book without reconverting it the next time you want to preview, and you can send your
original source file (e.g., EPUB, DOCX) or the KPF file to Amazon for publishing.
• Kindle Previewer doesn’t support export to MOBI or AZK when the language of the book is Arabic or one of
the Indian languages. These languages are available only with Enhanced Typesetting features, and MOBI and
AZK files don’t support Enhanced Typesetting.
• If you’re using ePub or other HTML-based formats, make sure that you have defined the right language, and
remove any unnecessary language definitions. Some third-party tools add additional language definitions that
are not necessary, which might be preventing Kindle Previewer from exporting your book.
1.7 Kindle Devices Simulated
Kindle eBooks work uniformly across platforms, but may look different to readers depending on the screen size of the
device. Kindle Previewer allows you to preview your eBook on the following device types:
• Tablet: Preview how your eBook displays on devices with larger screens, such as Fire tablets, Apple iPads,
and Android tablets.
• Phone: Preview how your eBook displays on devices with a smaller screen, such as phones.
• Kindle E-reader: Preview how your eBook displays on Kindle E-readers such as Paperwhite, Voyage, and
Oasis

• When the Default device is Tablet, the Aspect ratio list is displayed as shown in Figure 11. If the Default
device is Phone or Kindle E-Reader, the Aspect ratio option is not displayed because Kindle Previewer

2.1 Enhanced Typesetting
Kindle Previewer allows you to determine if your eBook is able to utilize Enhanced Typesetting. Enhanced Typesetting is a
series of typographical and layout features that improve readability and enforce more consistent display behavior across
Kindle reading platforms, including phones, tablets, and Kindle E-readers. Some Enhanced Typesetting features include:
Kindle Previewer User Guide
Amazon.com
• Drop caps that dynamically adjust with font size
• Hyphenation and smoother word spacing*
• Kerning and ligature improvements*
• Enhanced image and table formatting
• Page Flip
Note: These features might not apply to Japanese and Chinese content.
To determine if your eBook is able to utilize Enhanced Typesetting, first import your eBook into Kindle Previewer. If your
eBook supports Enhanced Typesetting, the Enhanced Typesetting label is displayed in the Preview and Navigation
Options pane as shown in Figure 13 and the Thumbnail pane is displayed as shown in Figure 14. If Enhanced Typesetting
is not enabled, the Enhanced Typesetting label and the Thumbnail pane are not displayed.

3 Using Kindle Previewer from a Command-Line Interface
To validate multiple books, you can run Kindle Previewer from a command-line interface.
Usage instructions: kindlepreviewer <input> <-command(s)> [-option(s)]
• Input: Specify the input file name here when processing a single file, or the input folder when processing
multiple files.
• Command(s): Include at least one of the commands specified in this table:
Commands
-convert
Create a KPF file in the specified output path or a Mobi file if the book doesn’t
support Enhanced Typesetting. Use the Enhanced Typesetting-compatible KPF file
to open the book in Kindle Previewer's graphical user interface.
-qualitychecks
Use this option to validate external links, internal links (excluding table of
contents), and footnotes in your books. This feature is currently in beta.
-showpreview
Open the converted book in Kindle Previewer's graphical user interface. This will
first convert the book, and then open it for preview.
-log
Use this option to generate only the log files for validation without generating a
KPF or a Mobi file.
• Option(s): Choose any of options specified in this table (optional):
Options
-output <output
path>
Path to the output folder. Use this option to specify a preferred path to store
output file(s) instead of the default path (input folder).
Kindle Previewer User Guide
Amazon.com
-locale
<localeoption>
Specify your preferred locale. Use this option to set the language for
conversion log messages and the Kindle Previewer user interface. Supported
locales: • en (English)
• de (German)
• fr (French)
• it (Italian)
• es (Spanish)
• zh (Chinese)
• ja (Japanese)
• pt (Portuguese)
• nl (Dutch)
Usage
examples:
• Validate multiple files: You can validate multiple files for publishing errors by providing a folder containing
the files as the input. To check the status of all the files, you can use the summary log file in the “output/”
folder. To review errors or warnings, use the individual log file inside the “output/Logs/” folder. Example:
“kindlepreviewer inputfolder/ -convert -output outputfolder”
• To validate internal links, external links, and footnotes in your book, you can include “-qualitychecks” when
you run kindlepreviewer. You can see the resultant Quality Report in the “output/Logs/” folder. Example:
“kindlepreviewer inputfolder/ -convert -output outputfolder -qualitychecks”
• Validate files individually: You can use Kindle Previewer to process files individually and generate a KPF file,
which is compatible with Enhanced Typesetting. There are three options:
• Use the “-showpreview” command to automatically open the book on the Kindle Previewer graphical user
interface without reconverting it.
• Use the KPF file to manually open the book without reconverting it. You can’t sideload KPF files to devices.
• Use the individual log file inside the “output/Logs/” folder to review any errors or warnings.
• Example: “kindlepreviewer inputfile.epub –convert” or “kindlepreviewer inputfile.epub –showpreview” or
“kindlepreviewer inputfile.epub –convert –qualitychecks”
• Generate log files only: You can use the “-log” command to validate books and generate just the log files
(summary log file, and the individual log files), without generating any output file.
• Example: “kindlepreviewer inputfolder/ -log”
