About

PDF9.Ai is a free, AI-powered PDF workspace that brings 68 tools into a single browser-based platform. It includes a PDF reader, full-featured editor, conversion suite, e-signature tools, and enterprise governance controls. Most operations run entirely in-browser, so files never leave the user's device. Nine built-in AI models enable document chat, summarization, and translation into 50+ languages at no extra cost. Key capabilities include merging, splitting, compressing, and organizing PDFs; converting to and from Word, Excel, PowerPoint, HTML, CAD, and image formats; OCR; PAdES/PKCS#7 digital signatures with audit trails; smart PII redaction; form filling for U.S. government forms; and document comparison. PDF9.Ai serves students, freelancers, legal professionals, accountants, HR teams, and enterprises. Teams benefit from SSO, RBAC, audit logs, and compliance-aligned infrastructure. Desktop apps are available for Windows and macOS.
