Book Maker: Interiors, Coloring Books, Low-Content Books and Covers in Your Browser
Make print-ready Amazon KDP books in your browser: interiors with the right margins, coloring books, notebooks and planners, and full-wrap covers with the exact spine width.
Publishing on Amazon KDP should be about your book, not about margins, bleed and spine math. Book & Print Prep, part of Compressify by MultiProductX, turns your pages, drawings or manuscript into print-ready files for KDP and other print-on-demand platforms. Everything runs in your browser: your files never leave your computer. We are constantly developing and updating our tool to stay ahead of the competition, seamlessly adapt to the latest platform requirements, save you valuable time in production, and completely eliminate technical complexities and frustrating rejection issues.
What Book & Print Prep does
The tool has three modes, one for each file a publisher needs:
- Interior pages — the inside of your book, as a 300 DPI print-ready PDF.
- Paperback cover (full wrap) — back cover, spine and front cover in one file.
- eBook cover — a 1600 × 2560 px cover for Kindle and other eBook stores.
Made for KDP and the other big platforms
Pick your platform and the tool applies its own bleed and safe-margin rules: Amazon KDP, IngramSpark, Lulu, Barnes & Noble Press, Magazine / Blurb, or a local print shop (3 mm bleed).
All the common trim sizes are ready: 5 × 8, 5.06 × 7.81, 5.25 × 8, 5.5 × 8.5, 6 × 9 (the most popular), 6.14 × 9.21, 6.69 × 9.61, 7 × 10, 7.44 × 9.69, 7.5 × 9.25, 8 × 10, 8.25 × 6 landscape, 8.25 × 8.25 and 8.5 × 8.5 square, 8.5 × 11, 8.375 × 10.875, A4 and A5. You can also type a custom size.
Choose your paper — white, cream, standard color or premium color — and the tool checks the KDP page limits for it. It warns you when a book is under 24 pages, the KDP minimum for a paperback.
Interior pages done right
The interior is where most KDP rejections happen. Book & Print Prep sets the exact page size with bleed and shows safe-margin and gutter guides. The gutter (the inside margin near the binding) grows with your page count, just as KDP asks, so text never disappears into the spine.
You also get:
- Page numbers at the bottom center or the outside corner, starting from any page you choose.
- A black & white preview that shows how your pictures will really print on a black-ink interior.
- Two ways to place images: fill the whole page to the bleed, or fit inside the safe area with a white border.
Coloring book maker
This is the fastest way to turn your drawings into a KDP coloring book — no Word, no layout software.
- Upload all your coloring pages at once: PNG, JPG, PDF or Word.
- They are placed in file-name order (01, 02, 03…), each one on a right-hand page with a blank back, so markers never bleed through to the next design.
- Your intro pages (title, copyright) stay at the start, exactly as they are.
Optional extras, one click each: a "This book belongs to" page, a color test page at the end so kids can try their markers first, and a "Thank you — please leave a review" page. Landscape drawings can be turned automatically to fill the page.
Low-content books in one click
Notebooks, journals and planners are the classic way to start on KDP. Pick a type, choose the number of pages and the line color, and the tool fills the whole interior inside the correct margins:
- Lined notebook (wide ruled or college ruled)
- Dot grid (bullet journal)
- Graph paper
- Daily journal (date + lines)
- Daily planner
- Monthly habit tracker
- Recipe book
- Sketchbook (frame + title)
- Blank pages
Add a "This book belongs to" page if you want, then make the cover — your book is ready to upload. Open it directly here: Low-Content Book Maker.
Typeset a novel, non-fiction book or poetry
Import your manuscript from Word, PDF or a .txt file and Book & Print Prep lays it out like a real book:
- Book fonts: EB Garamond, Libre Baskerville, Crimson Pro, Lora, Merriweather and Georgia, plus Amiri and Noto Naskh for Arabic.
- Justified or ragged text.
- Chapters that start on a right-hand page.
- Title and copyright pages, running headers, a table of contents and a big first letter (drop cap).
- Margins: KDP minimum (most text per page), comfortable (recommended), wide (poetry, large print) or your own.
When it looks right, export the paperback PDF — or a Kindle / EPUB file from the same text.
Stamps and decorations on your pages
Add a small drawing, logo or ornament and put it exactly where you want: on one page, on every page, on right-hand or left-hand pages only, or on the first page of every chapter. The tool can remove the stamp's background, and you control its size, opacity and rotation. Drag it on the page or click a spot, and place it behind the text as a watermark if you like.
Paperback cover with the exact spine width
The spine is the hardest part of a paperback cover, because its width depends on your page count and your paper. Book & Print Prep calculates it for you.
- Back, spine and front are each edited on their own.
- Left-to-right books (English, French) or right-to-left books (Arabic).
- Separate front and back pictures, or one picture across the whole cover.
- Spine fill: a color taken from the front cover, a color you choose, its own picture, or no fill.
- Text blocks for title, subtitle, author and back-cover paragraph — on the front, back or spine, horizontal or vertical, with bold, italic, alignment, shadow and outline.
The barcode area stays free, because KDP prints its own barcode there.
Cover finishes: full color, matte look, black & white matte, metallic silver or metallic gold.
A store-thumbnail preview, so you can check that your title is still readable when it is tiny on Amazon.
Open it here: KDP Book Cover Maker. For Kindle, use the eBook Cover Maker (1600 × 2560).
