Hi HN, I have been working on a set of PDF tools that does all the processing directly in the web browser. From time to time I needed to do some simple PDF manipulations like merging PDF files. Sometimes the files contain my personal data and I was not comfortable using other online services where the file usually is uploaded to a remote server. Behind the scenes there is a small library written in C++ doing the changes to the PDF files. I am using the Emscripten compiler to compile it to WebAssembly that is running in the browser. It was a very good learning for me and it was easier than I…

PDFBolt▲16Hi HN, I'm Michał. I posted PDFBolt here about a year ago as a basic HTML to PDF API.

Hi HN! I built PDFly — a PDF toolkit that runs entirely client-side. No file uploads, no server processing, no account needed. It has 56 tools including merge, split, compress, convert, redact, compare, and an AI chat feature to ask questions about your PDF content. Everything runs in your browser using [mention your tech stack if relevant, e.g., WASM/JS libraries]. Would love feedback on the tools, UX, or anything else!
