    PDFly – 56 free PDF tools that run in the browser▲10

    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!

    I do nothing in my dayjob for 95% of the Time so I made this▲34

    I had the problem of having a boring office job, where im not busy at all, i sit in an office and my bosses keep walking around. And i also enjoy scrolling (twitter) . So to fix this i made a simple free Chrome Extension to make it look like a PDF file. And here i made a little landing page for it. (am proud btw) : https://xdisguise.com/ So i made this :)
