Show HN: Privacy friendly suite of PDF tools

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 thought to get something working, credits to the Emscripten project. The tool is also a PWA and can be used offline (once loaded).

I am looking for any kind of feedback, comments or ideas for new tools that I could add.

Honestly, you should charge like $1 for each operation. People will trust it more that way, as you're not incentivized to snoop on their files (or put 500 ads everywhere).

Very cool, I like it. I resort to using smallpdf.com on occasion, would love to use this instead. Hope you will have a chance to add more features. What else do you think would be feasible browser side?

This is very cool. I had to build something similar but did it server side... client side seems like a much better option. My first thought was... I don't know of any client side pdf libraries that work in the browser... this seems like a good case for WebAssembly.
