About

Monstera PDF Editor is a free, open-source desktop application for Windows 10 and 11, with more than 150 tools for editing, converting, organizing, and securing PDF documents without subscriptions, accounts, or watermarks. Users can edit PDF text and objects, merge and split files, manage pages, create and fill forms, add signatures and annotations, compare documents, and permanently redact sensitive information. OCR in 14 languages makes scanned PDFs searchable. The built-in AI assistant supports 10 providers and can summarize, analyze, and answer questions about documents using the user's own provider credentials. Standard PDF operations run locally, and Windows AppContainer isolation helps protect the system while documents are processed. Distributed through the Microsoft Store, Monstera is licensed under GNU AGPL-3.0, and its source code is publicly available on GitHub.
