PDNob

Description

PDNob is a PDF productivity solution that spans free online tools, desktop apps for Windows and macOS, and a mobile app for iOS. Its free online editor lets you OCR, convert, sign, merge, compress, split, and organize PDFs without sign-up or watermark, handling common document tasks directly in the browser.

The desktop editor is built on a self-developed PDFium engine for fast handling of large PDFs, with high-accuracy OCR that converts scanned and low-quality documents into editable, searchable text while preserving layout. It supports editing text and images like a word processor, annotations, form creation, e-signing, password protection and redaction, batch processing, and conversion across 30+ formats.

PDNob's AI features let you chat with a PDF for source-backed answers, summarize documents at different lengths, translate while preserving layout, rewrite for clarity, and explain complex text, images, and formulas. An AI agent can select the right tools automatically for a given PDF task.

Developed as an independent brand within the Tenorshare organization and founded in 2022, PDNob emphasizes privacy with automatic data deletion, encryption, and GDPR and AES 256-bit standards. It offers a permanent free trial with feature limits alongside paid and lifetime licenses.
