Core Capabilities of PDNob Online

AI OCR PDF

Turn static scans and photos into dynamic, searchable documents using enterprise-grade optical character recognition — intelligently detecting tables, columns, and multilingual text.

Convert PDF

Convert PDFs to Word, Excel, PowerPoint, plain text, JPEG, PNG, or SVG — with intelligent layout retention and style preservation, not just raw text extraction.

Shrink file size up to 90% without visible quality loss — smart compression adapts to text density, image resolution, and embedded fonts for optimal balance.

Sign PDF

Create legally valid electronic signatures in seconds — upload your signature image, draw with touch/mouse, or type a styled name — all digitally sealed and audit-ready.

Protect PDF

Apply military-grade AES-256 encryption: set open passwords, disable printing/copying/editing, and assign granular permissions — perfect for HR records or client deliverables.

100% Free • No Login • No Limits
