A single HTML file that organizes your PDF pages locally, mobile friendly

Most PDF tools upload your files to servers you know nothing about. I wanted a tool that is fully private by design, not as an afterthought.

How it works

PDF.js renders the page thumbnails, pdf-lib builds the final output. Everything runs client-side, no backend, no server calls. It's a single .html file you can download and use offline.

What it does

* Merge pages from multiple PDFs * Drag and drop to reorder * Rotate and delete individual pages * Download as a single PDF * Touch drag support for mobile

Tested a 345-page PDF on my MacBook without any issues. Curious whether others experience slowness on larger files or older devices.
