PDF Page Splitter: Local-first A3-to-A4 PDF splitter (no uploads)

When I first started working with PDFs, I kept running into the same uneasy feeling. I just wanted to split a document — often something private, sometimes even sensitive — but every tool asked me to upload it somewhere. Some server, some cloud, some promise of “we’ll delete it later.” That never felt right to me. 🤨 I wanted a tool I could trust — because trust starts with not handing over your data at all. That’s why I built PDF Page Splitter as a pure frontend tool. Your PDF never leaves your device. No uploads. No tracking. No hidden background traffic. Everything happens locally, right inside your browser — like opening a document on your own desk and working on it with your own hands. 🔒💻 This approach isn’t just about privacy. It’s also about being respectful of real-world constraints. Uploading large PDFs burns time, data volume, and energy — especially on mobile devices, slow connections, or when you’re on the go. By keeping everything local, the tool is faster, more reliable, and much kinder to both your battery and your data plan. ⚡📶🌍 And then there’s the actual splitting. I’ve seen too many tools that “split” pages by re-rendering everything, bloating the file size in the process. That bothered me. Cutting a page should be like using a sharp blade, not a hammer. ✂️ So the splitting here is done properly: pages are rebuilt cleanly, content is preserved, and the PDF doesn’t suddenly grow just because you fixed its layout. In the end, this tool reflects how I think software should behave: respectful of your privacy, efficient with resources, and precise in what it does — nothing more, nothing less. ❤️📄
