PDF-X - Simple online tools to reduce, split, merge and protect PDFs

Hi Product Hunt! 👋 I'm the founder of PDF-X. We started this project with a simple observation: everyday document problems can waste a surprising amount of time. A file is too large for an upload portal. You need only a few pages from a long document. Several files need to become one. Or a document needs password protection before it can be shared. There are already many PDF tools available, but we wanted to build something focused on the result people actually need. PDF-X starts with four practical tools: • Reduce PDF Size — make large files smaller for easier uploading and sharing. • Split PDF — extract the pages you need. • Merge PDF — combine multiple documents into one file. • Protect PDF — add password protection before sharing. Our approach is simple: no installation, no account required, and no need to understand complicated document-processing settings. Behind the interface, we have also spent considerable time researching file processing, temporary storage, resource management and process isolation. Part of that engineering work became a separate open-source project called PDF-X Secure Runner. But for everyday users, the experience should remain straightforward: Upload. Fix. Download. This is our initial release, and we want to learn from real usage before deciding which additional features to build. I'd love to hear your feedback: What everyday PDF problem takes up the most time for you? Is there anything about the existing tools that feels confusing or unnecessary? Which document-processing feature would you like us to explore next? Thank you for checking out PDF-X! https://pdf-x.co
