Hi Product Hunt! 👋 The Problem: Like many of you, I frequently need to merge, compress, or edit PDF documents. But whenever I handled sensitive files, like contracts, tax returns, or bank statements... I felt incredibly uneasy uploading them to random third-party cloud servers just to perform a simple split or merge. The Solution: I didn't want my PDFs on someone else's server, so I built ZeroPDF. It is a 100% client-side, browser-based PDF workspace. By using WebAssembly and modern browser capabilities, all file processing happens locally on your device. Your files literally never leave your browser. 🛠️ What makes ZeroPDF different? Absolute Privacy: No servers, no uploads, no cloud storage. Bank-Grade Security: Apply AES-256 encryption purely on the client side. Smart Text Extraction: We built a spatial reconstruction algorithm to extract text from PDFs accurately, preserving paragraph structures. Instant Speed: Because there are no upload or download wait times, processing is instantaneous. The Full Toolkit: Merge, split, crop, watermark, and organize pages. I built this with React and styled it with shadcn/ui to keep the experience clean, fast, and minimalist. I would love for you to try it out, throw your most stubborn PDFs at it, and let me know how it holds up! I'll be hanging out in the comments all day to answer your questions and hear your feedback on what features I should build next.
