👋 Hey Product Hunt! PDFflow is a privacy-first PDF toolkit with 20+ tools that work entirely in your browser. **The Problem:** Most PDF tools upload your files to their servers. That's a privacy risk, especially for sensitive documents like contracts, financials, or personal files. **The Solution:** PDFflow processes everything client-side using WebAssembly. Your files never leave your device. No uploads. No tracking. No accounts required. **What you can do:** 📄 Merge & Split PDFs 🗜️ Compress (reduce file size by up to 70%) 🔄 Convert to/from Word, Excel, PowerPoint, Images ✍️ Sign documents with draw, type, or upload 💧 Add watermarks & page numbers 🔓 Unlock password-protected PDFs ✂️ Crop, rotate, reorder, delete pages ...and more **Pro Features:** ⚡ Unlimited batch processing 📊 Advanced compression levels ☁️ Template sync across devices 📈 Usage analytics **Built with:** Next.js 14, pdf-lib, Vercel 100% free for basic use. Pro plan for power users. Would love your feedback! 🙏

I've always wondered what happens to my PDFs once they're uploaded to these online sites. I don't use them much because I'm a graphic designer and I use professional tools, but for anyone who doesn't use them, I think this is a great solution that protects privacy. The basic version seems very comprehensive to me, so what's included in the paid version? Good luck with your project.

@marcoparisidesign Thank you for checking pdfflow out, its always a pleasure. In the paid version you get unlimited uses of pro tools as pro tools have a 4 file limit per day on the free plan. Doing this allows everyone to use the services for free or at least fully experiment with the website before making any financial decision.

Yet again, Thank you for checking pdfflow out and keep posted for any updates. I have a lot of stuff planned.
