I built a 100% local PDF merger — no uploads, no tracking, just a single HTML file

Hey r/SideProject! I was frustrated that every "free" PDF merger online uploads your documents to their servers, so I built a tool that does everything locally in your browser: ashiksagstrom-blip.github.io/pdf-merger How it works: - Uses pdf-lib (JavaScript library) to merge PDFs directly in the browser - Files never leave your device - Drag & drop interface with reordering - No signup, no watermarks, no ads - Works offline once loaded Tech stack: Single HTML file, Tailwind CSS, pdf-lib, SortableJS Hosted on: GitHub Pages (free) Code: github.com/Ashiksagstrom-blip/pdf-merger I added a small Buy Me a Coffee link in the footer for anyone who wants to support, but the tool is completely free. Would love feedback on: - Any bugs you find - Features you'd want to see added - UX improvements Thanks for checking it out!
