Show HN: Browser‑Based PDF Tools That Operate Without Uploading Files

A new submission on Hacker News showcases PDF tools that execute in the browser. The service, PDFcdf.com, processes documents locally without sending data to a server. Users can view, edit, and manipulate PDFs directly in their web browser. The approach enhances privacy by keeping files on the client device. No upload step is required, reducing latency and bandwidth usage. The tools are built with web technologies that run on modern browsers. The project aims to provide a lightweight alternative to cloud‑based PDF services. Community feedback is sought to improve functionality and compatibility.
