About

The universal PDF editor - create, edit and convert with ease. Ashampoo PDF Pro 2 is the complete solution to manage and edit your PDF documents. The program has everything you need to create, convert, edit, merge and protect your PDFs. Create perfectly sized documents that are readable on any device and use encryption to protect your property when needed. Your PDFs are now as easily editable as Word documents! If you use Ashampoo® PDF Pro 2 at home, you can run it on up to 3 PCs! A single license is enough to provide your entire family with a powerful office suite! If you use it commercially though, it's one license per installation. Ashampoo PDF Pro is not only ideal to fill out forms but also to create and edit your own. It takes only a few clicks to add interactive elements, like selection lists, checkboxes or input fields, to your PDF form. These forms can then easily be filled out by anyone using a standard PDF reader.

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.
