The app’s support for different formats enhances its utility in various scenarios, whether for academic purposes or professional use.

Another significant aspect of Pen&PDF is its emphasis on open-source software. Being open source means that the app's source code is publicly available, allowing developers and users to contribute to its development or modify it according to their needs. This transparency fosters a community around the app, where users can share insights, report issues, and suggest improvements.

Customization options further enhance the user experience. Pen&PDF allows users to adjust settings to suit their preferences, including theme settings, page layout, and more. This flexibility ensures that users can create an environment that works best for them, whether they prefer a light or dark theme or different page orientations.

Pen&PDF also includes features that support document sharing and collaboration. Users can easily share their annotated PDFs with others, facilitating teamwork and communication. This aspect is particularly beneficial for group projects or joint reviews, where multiple users need to provide input on the same document.

Users can expect quick loading times and responsive interactions, making document management efficient. The emphasis on performance allows users to focus on their tasks without being hindered by technical issues.

Moreover, Pen&PDF is designed to handle forms effectively, although it has some limitations regarding certain PDF forms due to character encoding issues within the underlying library. Users should be aware of these limitations when working with forms, as they may encounter challenges in specific scenarios.

As an open-source project, Pen&PDF invites contributions from users who wish to improve its functionality. This collaborative spirit encourages innovation and adaptation, allowing the app to evolve in response to user feedback and technological advancements.
