I built a 100% private PDF toolkit that runs entirely in the browser (No server uploads)

Hey everyone! I just launched PDFLabs, a free web toolkit for PDFs.

The biggest difference between this and sites like iLovePDF is that it has no backend server. Everything runs locally in the browser using JavaScript (pdf-lib & pdf.js). When you drop a file to merge, split, or compress it, the file never actually leaves your device.

It has 13 tools right now:

Merge / Split / Reorganize / Delete / Rotate PDFs
PDF to Images / Images to PDF / Text to PDF / Extract Text
Compress PDF / Add Watermark / Add Page Numbers / PDF Info
Try it out here: https://roaring-mermaid-ba6504.netlify.app

I’m a solo developer, so I’d love to hear your feedback on the UI/UX, mobile responsiveness, and how it performs on larger files. Brutal honesty is appreciated!
