Show HN: A privacy-first, client-side toolbox (PDF, Imgs, Dev) no server uploads

I’m Linus. I built this toolbox because I was tired of searching for "PDF Merger" or "Image Compressor" and having to upload sensitive files to random servers filled with ads and tracking.

The goal was to build a suite of utilities that runs 100% client-side using WebAssembly and standard Web APIs.

Features: - PDF Tools (Merge, Split, Watermark) using pdf-lib/pdf.js - Image Tools (Compress, Resize, EXIF strip) using JSZip and Canvas - Dev Helpers (JSON/SQL formatting, JWT debugging) - 0% Server-side processing - PWA support (works offline)

It’s built with Vanilla HTML/JS (no build step required) and hosted via simple FTP. No analytics, no cookies.

Source code (GnuGPLv3) is here: https://github.com/immineal/linu-li

I’d love to hear your feedback on the implementation or ideas for other client-side tools I should add.
