PDF Unshare is a utility designed to safeguard PDF files by creating unshared versions that prevent unauthorized sharing, printing, editing, copying, or access. This innovative document protection software enables users to establish an expiration date for the protected PDFs, ensuring that the documents become inaccessible after that specified period. This tool is especially beneficial for entrepreneurs, book publishers, and educational institutions seeking to prevent unauthorized distribution of their materials online or to other individuals. With the free Unshared PDF reader program, users can view the protected files on Windows PCs, laptops, iPhones, iPads, and Android devices, with the added feature that it blocks screenshot functionality while the document is being viewed. Moreover, users have the capability to add custom watermark text and select a color for the watermark, enhancing the level of personalization for their protected documents. By utilizing this application, users can maintain greater control over their intellectual property, ensuring it remains secure and private.

Files are transmitted through a secure, encrypted channel, ensuring their safety throughout the process. Once the files have been handled, they are completely erased from the system. For images, they are enhanced and saved at a JPEG quality setting of 65%, which is generally suitable for a variety of uses. However, if you require higher quality, there is an option to adjust the settings for better image resolution, though this may result in larger PDF file sizes. Files are consistently secured during upload and maintained in a protected state until they are permanently eliminated after processing.

Generate PDFs for free, compress them, split and merge files, secure documents with encryption, and design forms with ease, all from any Windows application. Seamlessly add form fields, text stamps, watermarks, letterheads, and more to enhance your PDF documents. The user interface is both attractive and intuitive, eliminating the need for lengthy training sessions. Simply launch additional software like CIB doXisafe or CIB fairBrief following PDF creation. The system also accommodates the document standard for individuals with visual impairments. Numerous customization options allow you to define profiles for different use cases and customize menu labels to fit your needs. With a flexible interface, integration into your existing system is straightforward. You can create PDFs, compress files, edit extensively—including re-sorting, rotating, and deleting pages—merge PDFs, fill out forms (marked with a DEMO stamp), and explore many more features!
