The same four-step pipeline KDP self-publishers we talk to use to ship a puzzle book in a weekend.
1. Pick a niche and trim size
Most KDP puzzle books use 6×9 (compact paperback) or 8.5×11 (large-print senior editions). Pick trim before you generate so margins land cleanly.
2. Generate puzzles in batches
Choose a generator, set your batch size, and download PDFs. The free tier covers small-to-mid-size books; Premium (now live) unlocks batches up to 100 and watermark-free export.
3. Combine PDFs into a single manuscript
Use Adobe Acrobat, PDFsam, or Mac Preview to merge your puzzle PDFs and answer-key pages into one file. Add a title page and table of contents.
4. Upload to KDP
Open Kindle Direct Publishing, create a new paperback, upload your manuscript and cover, set categories and keywords (Book Bolt below is what most publishers use for keyword research), and publish.
Premium is live for KDP creators today
Watermark-free PDFs, editable Word/Google Docs export, custom fonts & trim-friendly layouts, and batches up to 100 are available right now — from $2.99 for a day pass.
Coming for KDP — founding waitlist
A one-click KDP book builder is on the way
We’re building KDP-specific power tools on top of Premium: a one-click book builder that compiles 100+ puzzles into a single print-ready manuscript, automatic bleed/trim/gutter for every KDP size, a page-count-aware cover helper, and organized bulk export. Join the founding waitlist for early access and lifetime founding pricing.
Free puzzle generator for KDP commercial use — what to know
The phrase “free puzzle generator for KDP commercial use” gets searched a lot because most free puzzle makers fall short in one of three ways: they cover the PDF in watermarks, they restrict commercial use, or they don’t support KDP paper sizes. PuzzlePage was built specifically to clear all three bars.
Branding policy
Free downloads keep the puzzle grid completely clean — no watermark stamped across the puzzle. The only branding is a small “Made with PuzzlePage.app” credit line at the bottom of the page. We keep the free tier genuinely usable for KDP work and earn our keep through Premium — which adds a fully watermark-free export — and affiliate partners.
License
You own the output. Sell it on KDP, sell it on Etsy, give it away as a lead magnet, use it on a worksheet subscription site. No attribution required, no per-unit royalty. The same model as a royalty-free stock asset.
KDP-ready PDF format
Every PDF is print-resolution, in one of the four KDP-accepted trim sizes (6×9, 7×10, 8.5×11, A4), with a separate answer-key page so a single download equals one ready-to-bind chapter. Upload it to KDP directly — no reformatting, no margin adjustments, no font-embedding step.
Frequently asked questions about KDP puzzle books
Can I use PuzzlePage’s puzzles in books I publish on Amazon KDP?
Yes. You have full commercial rights to puzzles you generate. They can be sold in Kindle Direct Publishing activity books, sold on Etsy or your own site, included in lead magnets, or used in any commercial product.
Do the free puzzle PDFs have any branding?
Free downloads include a small “Made with PuzzlePage.app” credit line at the bottom of the page. The puzzle grid itself stays clean, with no watermark across it. A watermark-free export is available now on the Premium tier.
Which paper sizes work for KDP puzzle books?
PuzzlePage exports US Letter (8.5×11”), A4 (210×297mm), 6×9” and 7×10” — the four sizes KDP supports for paperback puzzle books. 6×9 is the most common KDP trim; 8.5×11 is preferred for large-print senior editions.
Do I need to credit PuzzlePage in my KDP book?
You own full commercial rights to the puzzles you generate — the license is like a royalty-free stock site. Free PDFs carry a small “Made with PuzzlePage.app” credit line at the bottom of the page; removing that line is available now on the Premium tier.
Can I batch-generate hundreds of puzzles?
The free tier allows up to 5 puzzles per generation, and up to 10 per generation after a one-time email verification. Premium (now live) unlocks batches up to 100 puzzles and watermark-free export; a one-click KDP book builder is on the way for founding members.
