What will you make?
Not enterprise publishing software. Not a template generator. SpreadViewer is for the book you've been meaning to finish — the one that deserves to look exactly the way you imagined it.
Full-page image blocks, panel layouts for sequencing art across spreads, square and landscape formats — everything a children's book needs to look like it belongs on a shelf. Drop in your illustrations, set the layout, see exactly what the printer will see.
Text shapes that turn lines into visual art. Page colors that set the mood of a section. Dividers that breathe space between poems. Your words were always good — now the page can match them.
Clean chapter structure, precise typography, and photo spreads that look like a real published book — not a Word doc with better margins. See every spread as a reader will before a single copy gets printed.
How it works
SpreadViewer runs in Chrome on your desktop. Open the file, upload your manuscript, and you're looking at your book.
Paste in your text or upload your document. Choose your KDP trim size — 6×9, 5×8, 5.5×8.5, and more. SpreadViewer pours your words into the correct template with real margins and gutters.
Left page and right page, side by side, exactly as a reader will hold it. Check your page count, see how chapters break, spot any layout problems before they become print problems.
When it looks right, export it. SpreadViewer outputs your spread at the exact trim size you chose — pixel-perfect, ready to upload to KDP. No resizing, no margin math, no surprises at the printer.
Use whatever computer you want — but make sure to export in Chrome. That's what makes the exact dimensions possible.
And one more thing
"I've never seen an affordable tool that lets you do this to a book interior."
Triangle, Diamond, Hourglass, River, and Chalice — visual arrangements of your prose that you won't find in Word, Vellum, or any other tool at this price. Around 170–185 words per shape hits the sweet spot. Play around with the font size, too — it helps hone the shape just right.

Elegant typographic separators between scenes and sections. The kind of detail that makes a book feel finished.
The paid feature
When your spread looks right, export it. SpreadViewer outputs a print-ready file at the precise trim size you chose — not close, not approximately, exact.
No resizing in another app. No margin math. No "is this the right size?" anxiety at upload. Just your file, the right size, ready to go.
SpreadViewer runs in Chrome on desktop. That's what makes the precise export possible — Chrome's PDF engine handles the exact dimensions reliably. Other browsers don't.
From the maker
SpreadViewer is the tool I wanted. It's honest about what it is — a viewer, a formatter, a confidence-builder before you print. Not a word processor. Not InDesign at a discount. Just the thing that answers the question every KDP author asks: will this actually look right?
And personally, I think subscriptions are getting out of hand. So once you pay, it's yours forever.
Let me know if you want a new feature or something rearranged and I'll try to add it. Email me directly. I'll see what I can do to help.

Yes. Upload your manuscript, pick your trim size, and see your real spread — margins, gutters, page count, everything. No credit card. The export is what costs $39.99.
The export outputs your spread at exact KDP dimensions. Chrome's PDF engine handles that precisely. Other browsers don't — the dimensions come out wrong. It's not an arbitrary restriction, it's what makes the export reliable.
SpreadViewer works with Word documents and plain text. Most authors write in Word or Google Docs — export to .docx and you're ready to go.
Triangle, Diamond, Hourglass, River, and Chalice — visual arrangements of your prose that you won't find in Word, Vellum, or any other tool at this price. Around 170–185 words per shape hits the sweet spot. Play around with the font size too to really hone the shape.
No. I think subscriptions for tools like this are the wrong model. You pay $39.99 once and it's yours. Future updates included. No renewal, no account.
No, you'll need to use your desktop or laptop. SpreadViewer is not optimized for mobile.
Email me directly. Let me know if you want a feature or if something isn't working properly and I'll take a look at it.
