• PDF text editing. The core functionality of Master PDF Editor resides in modifying textual content. Users can select any text block within a PDF document and edit it directly, changing the font, size, color, and text position. This feature eliminates the need to revert to the original document for minor corrections or content updates.
• Graphical object manipulation. The program allows inserting and modifying visual elements such as images, shapes, and lines. Users can adjust the properties of these objects, including their size, orientation, and transparency. This tool is essential for creating diagrams, adding corporate logos, or visually annotating technical plans and designs.
• Page management. Master PDF Editor offers a set of tools for the structural organization of documents. Available functions include extracting specific pages to a new file, inserting blank or imported pages from other documents, rotating pages to correct orientation, and deleting unwanted pages. It also allows merging multiple PDF files into a single document.
• Form creation and editing. The software includes capabilities for designing interactive PDF forms. Users can add text fields, checkboxes, radio buttons, and drop-down lists. Once the form is created, it can be filled digitally, saving the entered data without altering the static design of the document.
• Document annotation and markup. For review workflows, the application provides annotation tools. Users can highlight text, underline paragraphs, strike through obsolete content, and add sticky notes or text comments. These annotations are fundamental for collaborative review of drafts and contracts.
• Digital signatures and certificates. Master PDF Editor supports digitally signing documents to validate the authenticity and origin of the content. Users can create their own signatures or import existing digital certificates. The signing process applies a cryptographic stamp that detects any subsequent modification to the document, ensuring its integrity.
• Document encryption and security. Password protection is implemented to restrict unauthorized access to files. The program allows setting specific permissions, such as prohibiting printing, text copying, or content modification, using standard encryption algorithms to ensure the confidentiality of sensitive information.
• PDF and XPS format conversion. The tool acts as a bridge between PDF and XPS formats, allowing bidirectional conversion. Users can open XPS files and edit them with the same tools as a PDF, or save them in PDF format. This functionality is useful in environments where both document standards coexist.
• Export to image and text formats. Document content can be exported to other formats for reuse. Master PDF Editor allows extracting entire pages as JPEG or PNG images, and also exporting document text to plain text files, facilitating information extraction for processing in other applications.
• Watermarks and stamps. For document customization or status indication, the program includes the ability to add watermarks and stamps. Custom text or images can be inserted as a background or overlay on all pages or a selected range, indicating concepts such as "Confidential," "Draft," or "Approved."
• Cross-platform compatibility. Master PDF Editor is available for major operating systems, including Windows, Linux, and macOS. This compatibility ensures users can work with the same files and functionalities regardless of the platform they use, facilitating document exchange in mixed work environments.

Master PDF Editor is developed by Code Industry, a software company based in Riga, Latvia. The development of the application began in 2013, with the goal of creating a native PDF editing tool for Linux that later expanded to other platforms. The program is primarily written in C++ using the Qt framework for the graphical interface, which facilitates its portability across different operating systems.
