Your app

Download the PDF Builder (ZIP file)

KDPEasy Activity Book PDF Builder.zip · a small file, about 27 KB. No key, no account and no password.

  1. Download the ZIP file to your computer.
  2. Extract it first (right-click the ZIP and choose Extract All or Unzip). It will not run from inside the ZIP.
  3. Double-click index.html in the extracted folder. The app opens in your web browser. A README.txt in the same folder explains every step.

Use a current Chrome or Edge on Windows or Mac. The app works offline, and your pictures stay on your own computer. Nothing is uploaded.

How to build your PDF

  1. Your book. Click Open book file... and choose the file your Prompt Kit saved. It fills in the page size and shows each page's title. To get that file, click Save book file in the Prompt Kit (under Book settings). No book file? You can choose the page size by hand (8.5 x 8.5 in or 8.5 x 11 in). Two options are ticked for you: a blank back page after every picture, and a title page plus a copyright page. You can untick either one.
  2. Your pictures. Drop in your ChatGPT pictures (PNG or JPG). The app puts them in order and matches them to your plan. You can move, preview or remove any picture, and the app tells you if the number of pictures differs from your plan or if a picture looks too small or gets cut off.
  3. Title and copyright pages. Type the book title, your name and the year. These pages are printed exactly as you type them.
  4. Build the PDF. Check the summary (picture count, KDP page count, inside margin, picture width and rough file size), then click Build PDF. You get one PDF named after your book title, for the inside of your book. The order is: title page, copyright page, then each picture followed by a blank back.

Please open the PDF and check the first pages and a few pictures before you upload it to KDP. The app builds the inside of the book only: no cover, no pictures and no upload. It follows KDP's published margin and page rules as read on 2026-11-03, and KDP can change them, so check KDP's help pages when you publish. KDP reviews every book itself, and a printed proof copy is still a good idea.

Good to know

Sharper lines, not extra detail

Black-and-white line art that has to be enlarged is cleaned up and sharpened (you can switch this off). Color pictures are left alone. The app cannot add detail that is not in the picture.

About picture quality

Every page of the PDF is built at 300 DPI, as KDP recommends. A plain ChatGPT picture placed on the page is only about 130 DPI, so bold lines usually print readable but a little soft. Order a printed proof copy before you publish.

Telling KDP about AI

KDP asks authors to say when a book contains AI-generated content. Pictures made in ChatGPT count, so answer that question honestly when you set up your book.

If something goes wrong

Nothing happens when I open index.html

Extract the ZIP first, then open index.html from the extracted folder.

A picture could not be read

Save that picture again as PNG or JPG and add it again.

A long book is slow

A big book takes time and memory, and a long one can take several minutes. Close your other browser tabs, or build the book in two parts.

The app shows a note about 24 pages or a page limit

KDP needs at least 24 pages in a book. The top limit is 590 pages on 8.5 x 11 in and 828 pages on 8.5 x 8.5 in. The app tells you which limit applies.
