Use 100% free, private, client-side PDF tools to merge, split, protect, sign, and convert images to PDF with no server uploads.

Hi Product Hunt! 👋 I'm the maker of ScanFlow PDF Suite. I was frustrated by how almost every free PDF tool (like iLovePDF) forces you to upload your sensitive documents—like bank statements, legal contracts, or IDs—to their servers. Not to mention the hidden paywalls and slow processing times. So, I decided to build a completely private alternative. ScanFlow is a suite of PDF tools (Merge, Split, Protect, Sign, and Image-to-PDF) built with Next.js and WebAssembly. The catch? It processes everything 100% client-side. 🔒 Zero Server Uploads: Your files literally never leave your browser. ⚡ Blazing Fast: No waiting for files to upload or download. 💸 100% Free & No Limits: Zero server costs for me means it's completely free for you. We also have a mobile app, but I wanted to make the core web tools accessible to everyone without any sign-ups. I'd love for you to try it out with a dummy PDF (or a real one, it's safe!) and let me know your feedback on the UI and processing speed. Happy to answer any technical questions about the client-side architecture!

Merged a few contracts in Chrome and it worked instantly without uploading anything, which is exactly the kind of no-fuss tool I keep bookmarking. Splitting by page range was surprisingly quick too.

@phoenix_rong Awesome to hear! That 'no-fuss, instant' experience is exactly what we were aiming for with the client-side processing. Glad the merging and splitting worked smoothly for your contracts! 🙌

Since it made it to your bookmarks, what other PDF tools or features would you recommend we add to the suite next?
