How to Convert a JPG to 300 DPI for KDP

To convert a JPG to 300 DPI for KDP, you need to make sure the image has enough pixels for the size it will print. Simply changing a DPI label is not enough if the image is too small.

Step 1: Find your print size

Decide how wide and tall the image will appear in the book. For example, if the image is 5 inches wide, multiply 5 by 300. You need 1,500 pixels of width.

Step 2: Check your JPG dimensions

Right-click the file and check image properties. If the width and height are too small, the image may need to be upscaled.

Step 3: Export carefully

For photographs, JPG is usually fine. Use a high-quality export setting to avoid compression artifacts.

Quick formula

Required pixels = print inches × 300.
