By using this application, users not only enhance the security of their intellectual property but also retain more control over how their content is accessed and shared in various contexts. Ultimately, this robust tool ensures that sensitive information remains confidential while offering flexibility and user-friendly features for document management.

Files are sent via a secure and encrypted channel, guaranteeing their protection during transmission. After processing, these files are thoroughly deleted from the system to prevent any unauthorized access. Images undergo enhancement and are stored at a JPEG quality setting of 65%, which is typically adequate for numerous applications. Nonetheless, there is the possibility to modify the settings for improved image quality if needed, although this may lead to increased sizes of the resulting PDF files. Throughout the upload process, files are kept secure and remain in a safeguarded condition until they are permanently removed following processing. This comprehensive approach ensures that user data remains confidential and secure at every stage.

Create and manage PDFs without cost, while also being able to compress, split, and merge documents, as well as secure them with encryption and design forms easily, all from any Windows-based application. Enhance your PDF files by effortlessly adding form fields, text stamps, watermarks, letterheads, and additional elements to improve their appearance and functionality.
