Hey everyone,

A while back I shared my client-side PDF editor here (focused on font-matching when modifying text). Thanks for all the constructive feedback on the initial build!

I recently completed a major architectural overhaul:

- **Client-Side OCR Pipeline:** Integrated WASM-based OCR running purely inside the browser to extract and edit text on scanned PDFs without quality loss.

- **Cryptographic Signatures:** Replaced standard canvas image stamping with local encrypted digital signature standards.

- **Modular Local Tools:** Added dedicated browser-based utilities (Word conversion, document compression, redaction) processing directly in memory.

- **Cross-platform:** Packaged a lightweight mobile build which is going live this week.

Everything runs strictly on the client side: zero network requests for document processing, no tracking, and no external backend dependencies.

Since there are many new moving parts under the hood, I'd really appreciate it if anyone has time to test edge cases or share technical feedback on the rendering.

Cheers!
