Opening a KDF File
The KDF file type is primarily associated with Kindle for PC.
What is a KDF file
Consider these examples:
- Kindle Database File: Kindle for PC uses an SQL‐based structure to store e-book metadata. This format helps manage your e-book library. More information is available at Kindle Reader.
- Kodak Digital File: Used by Kodak EasyShare (and related programs) to store digital images or film data. It can also appear as a Kodak EasyShare image.
- Keysight Test Data File: Employed by Keysight Technologies, this file stores test data and is often compressed using the BZ2 algorithm.
- Knit Design File: Created by KnitBird, this format saves knitting patterns. It uses GZIP compression. More details can be found at KnitBird.
- Kinko's Document Format / Kindle Format 8 eBook: Sometimes the KDF extension is used in document management or e-book creation environments, such as with software like Kindle Comic Creator.
FilExt.com tip: Each variant is tied to its originating application. Use the specific program to open and view your file, and always back up the original before making any changes.
How to open a KDF file
You need a suitable software like Kindle for PC to open a KDF file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your KDF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a KDF file directly in the browser:.

Programs that open and convert KDF files:
- Kindle for PC
See the previous paragraphs to learn more about the main application. KDF files are often referred to as Kindle for PC databases because this type of file is primarily created or used by this software.
- Kinkos Photo by Kinko's, Inc.A prep file used by Kinkos. Program ID is KFP KDF.Document
- VisiQuest ((Khoros) Standard Data Format) by AccuSoftThe Khoros Pro product line was taken over by AccuSoft Corporation and a newly-branded release of the Khoros Pro product line is now called VisiQuest.

KDF file format:
Every file has a defined file format, i.e. how the data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. In the following you will find our evaluation of the KDF files:
The KDF file extension includes various formats for various programs. The following file formats are most commonly found in KDF files:
- 30% of all KDF files are based on the popular SQL file format. An SQL file contains a lightweight SQLite database, widely used in application development for storing application related data. These are binary files, so they do not contain words or text. The files are on average 720 KB in size and range from 79 KB to 1 MB. The file type is relatively new. The following keywords are characteristic: SQLite format 3. book.kdf is a typical file name.
- 20% of all KDF files start with the magic bytes 00 00 00 00 00 00 00 00, which are always the first bytes of this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are on average 190 bytes in size and range from 190 bytes to 190 bytes. Several words can almost always be found in the files, e.g. DCIM. Such KDF files store data about imagen.
All the rest of the KDF files (50%) have different formats, frequently e.g. BZ2, GZIP, UTF-16 (BE), PDF and KDF. These files sometimes refer to pngamd, calculator, hardware, spilhs, vision or kiwi. Drag & drop your file here to see the file format and a preview of your KDF file!
