https://freeflipbook.com
1•pang_shijiu•2h ago
Hi HN community,

I’m excited to share FreeFlipbook (https://freeflipbook.com/), a platform I’ve been working on to make it easy for anyone to create and share interactive digital flipbooks. Whether you’re a designer showcasing a portfolio, a teacher creating engaging educational materials, or a small business promoting products, FreeFlipbook lets you turn PDFs or images into responsive, mobile-friendly flipbooks with a realistic page-turning effect.

Some key features:

Simple Creation: Upload a PDF or images, and our tool automatically converts them into a flipbook with customizable themes.

Interactive Elements: Add links, videos, or annotations to enhance the reader experience.

No-Code Integration: Embed flipbooks on your website or share them via a unique URL.

Tech Stack: Built with C#,.NET core,Tailwind, optimized for performance and scalability.

I’d love to hear your feedback on the UI, features, or potential use cases. Have you used similar tools for digital publishing? What features would make this more useful for you? Looking forward to your thoughts!
