Free ISBN Barcode Generator (Convert ISBN to Barcode)

How to Convert ISBN to Barcode for Amazon KDP

If you are self-publishing, you need to turn your 13-digit ISBN number into a graphic that scanners can read. Follow these simple steps to generate your free barcode:

• Step 1: Enter ISBN: Type your valid 13-digit ISBN (starting with 978) into the first box.
• Step 2: Add Price (Optional): If you want to embed a price, enter the 5-digit EAN code (e.g., 51499 for $14.99). Leave this blank if you are using Amazon KDP's standard barcode.
• Step 3: Generate: Click the "Generate Barcode" button. Watch the counter increment!
• Step 4: Download: Save the PDF file for your book cover designer or use the PNG for mockups.

Understanding the Barcode Components

An ISBN (International Standard Book Number) is your book’s unique fingerprint. The barcode is simply that number translated into lines (EAN-13 standard).

Do You Need a Barcode?

• YES: If you are printing physical copies (Paperback/Hardcover) to sell in stores or online.
• NO: If you are only publishing an eBook (Kindle/EPUB). Digital books do not need scanable barcodes.

Price Codes (EAN-5): Which One to Use?

Our tool now supports the optional 5-digit price extension.

1. No Price (Recommended for KDP)

Leaving the price field blank generates a standard EAN-13 barcode. This allows you to change the book's price later without redesigning the cover.

2. The "90000" Placeholder

Entering 90000 tells retailers: "This book has an ISBN, but no fixed price is printed on the cover."

3. Fixed Price

To encode a specific price (e.g., $9.99), the first digit is the currency (5 = USD) followed by the price. So, $9.99 becomes 50999.
