Use the Windows and Mac desktop apps or the iOS app to read, edit and manage PDFs wherever you are.
PDNob PDF Editor is aimed at people who work with PDFs daily and want the core toolset plus a layer of automation. The suite covers reading, text and image editing, annotation, page organization, forms, signing, protection and compression, and it handles batch conversion between PDF and more than 30 formats including Word, Excel, PowerPoint, EPUB, images and PDF/A while preserving the original layout.
Its AI layer is what differentiates it from a classic editor. An AI PDF agent can summarize long documents, answer questions about their contents with source-backed responses, and translate PDFs. The OCR engine, built with Tenorshare's ADRT technology, turns scans and skewed or low-quality pages into editable, searchable PDFs across 16+ languages, with automatic deskewing and denoising beforehand. Tenorshare also touts a self-developed PDFium-based engine that opens large documents quickly without lag.
The product spans Windows 10/11, macOS and an iOS app, and is available as a free download alongside a lifetime license option and team pricing. Because it belongs to the wider Tenorshare PDNob family, it pairs naturally with the company's image-to-text and image translator utilities for a document workflow that stays in one ecosystem.
Redline text, add annotations and signatures, watermark drafts and export to Word or PDF/A without installing several separate tools.
OCR digitized papers and textbook pages into searchable PDFs, then use the AI agent to summarize them or answer questions about their content.
Convert, compress, merge, split and password-protect large batches of PDFs with consistent output formatting.
Translate PDFs into other languages and keep the layout usable for review, sharing or archiving.
