Free PDF to 3D Flipbook Converter
Real 3D page physics, not the 2D CSS flips of Issuu and Flipsnack. 3 projects free. Pro $3/mo vs Issuu's $35/mo.
How it works
Three steps. About a minute.
Upload your PDF
Drag the file into the browser. Pages are extracted client-side, so the file stays on your device until you choose to publish.
Customize the cover and dock
Pick a cover color matching your brand, set the title font, add clickable links in the dock (your site, IG, Calendly, whatever). Or accept the defaults.
Share the link or grab the iframe
Hit publish. Send the URL by email/WhatsApp/QR, or copy the iframe code into Notion/WordPress/Webflow/Carrd/Framer/Squarespace.
What you get
Built for the way people actually share things
Real 3D physics, not CSS-faked 2D
Pages turn with weight and momentum. Issuu, Heyzine, and Flipsnack render flat CSS page-flips. Side by side it's not even close — i3dify feels like a real magazine on a phone.
Cheapest path to remove branding
Pro at $3/month removes the i3dify pill AND adds custom domain AND analytics. Issuu charges $35/month for the same featureset. Heyzine wants $13/month for the custom-domain tier. We're 4-10x cheaper.
Mobile-touch optimized
Pinch zoom, swipe to flip, fullscreen one-tap. 70%+ of viewer traffic is mobile in 2026 — built for that. No app install for viewers.
Embed in Notion, WordPress, Webflow, Carrd, Framer, Squarespace
One iframe code (or URL paste in Notion). Step-by-step guides per platform on the site. No WordPress plugin to maintain.
Streams big PDFs page-by-page
Free includes 50 MB total storage. The 3D engine streams pages on demand so even 200-page catalogs load in under 1 MB initially. Works on 3G.
Password protect for client previews
Lock unlisted flipbooks behind a password for client deliveries, board reviews, or sensitive internal docs. Pro unlocks unlimited password-protected projects.

| Heyzine | $8/mo | Cheaper than Issuu, 2D page-flip. Custom domain only at $13/mo Pro tier. |

FAQ
Quick answers
Do I need to sign up to try it?
No. Upload a PDF and preview the 3D flipbook before creating an account. You'll only sign up when you want a permanent share link.
Does the free plan have a watermark?
Yes — a small i3dify branding pill stays in the corner of the viewer on free. Pro at $3/month removes it, unlocks unlimited projects, adds custom domain, and adds analytics.
How is this different from Issuu, Heyzine, or Flipsnack?
All three render PDFs as 2D CSS page-flips. i3dify renders pages as textures on real 3D book geometry with weighted physics — visually distinct on mobile especially. Pricing is also different: Pro at $3/mo vs Issuu's $35/mo, Heyzine's $8/mo, Flipsnack's $14/mo entry tiers.
Can I embed it on my website?
Yes. Every published flipbook has an iframe embed code. Step-by-step guides available for WordPress, Notion, Webflow, Carrd, Framer, and Squarespace. Any platform that allows custom HTML works.
Does it work on mobile?
Yes, mobile-first. Touch-optimized: tap to turn, pinch to zoom, swipe through pages, tap fullscreen. No app to install — it's a regular web page.
How is this different from a normal PDF viewer?
A PDF viewer renders pages flat. i3dify renders the PDF as a real 3D book with weighted page-turning physics, cinematic lighting, and a configurable cover. The format drives 2x time-on-page for visually-driven content (catalogs, lookbooks, restaurant menus, portfolios, brochures).
