TL;DR: PDNob Pro PDF Editor handles editing, OCR, conversion, signatures, and batch processing, while AI can summarize and answer questions about your files. Lifetime access is $49.99 (reg. $349.95).

The PDF you need to edit is, naturally (and unfortunately), almost never in an editable format. PDNob Pro PDF Editor handles text changes, OCR, conversions, signatures, and the usual document mumbo jumbo, then uses AI to summarize and answer questions about your files. For a limited time, you can grab a lifetime subscription to the service for $49.99 (reg. $349.95).

Whether you need to change a typo, sign a form, or just delete one unnecessary page, PDNob lets you do it all in one place, along with a few features that go well beyond basic document editing. Even better for households or small teams, one purchase supports two users with simultaneous use on two devices, so the license doesn’t have to spend its entire life tied to one computer.

PDNob lets you change existing text, fonts, colors, links, layouts, and images directly inside a PDF. You can also add page numbers and watermarks, redact information, fill and sign forms, or rearrange a document without rebuilding the whole thing somewhere else.

Other nifty features include:

• OCR for scanned documents: Extract text and turn scanned contracts, receipts, books, and other image-based files into editable, searchable PDFs.
• File conversion: Move between PDF and formats including Word, Excel, PowerPoint, TXT, and images while preserving the original formatting.
• Document organization: Merge, split, rotate, reorder, extract, or delete pages.
• Annotations: Highlight passages, leave comments and sticky notes, add stamps, or draw directly on a document.
• Batch tools: Convert, compress, organize, or run OCR on multiple files rather than handling them individually.

There’s also PDF compression for shrinking unwieldy attachments and password and permission controls when a document isn’t meant for everyone.

Its AI tools can tackle the contents of a document as well. You can chat with a PDF to ask questions about it, generate a summary, pull out key points, translate passages, or rewrite text. This could make a particularly lengthy report, research paper, or instruction manual easier to navigate when you only need a tiny piece of information. The lifetime license comes with 6,000 AI credits, so it’s worth noting that AI usage isn’t unlimited.

20GB of cloud storage is available, too, giving you another place to keep documents accessible, while support for Windows, Mac, and iPhone means you’re not restricted to a single desktop operating system.

Formerly $349.95, you can grab lifetime access to PDNob Pro PDF Editor for only $49.99, with two-user support and lifetime updates included.
