Ultra PDF Merger is a free and portable PDF file merging utility designed to combine multiple PDF documents into a single file with minimal effort. Built using C# on the Microsoft .NET framework, this lightweight tool focuses on doing one job well: merging PDFs quickly and reliably without unnecessary features or bloat.
This standalone executable is ideal for users who frequently need to combine reports, scanned documents, or downloaded PDFs into one cohesive file. While it does not require installation, it does rely on the Microsoft .NET Framework 4.0 to function properly. Users can easily control the order in which PDF files are merged and remove unwanted files from the queue before generating the final document.
Ultra PDF File Merger
Ultra PDF Merger was created to address common frustrations found in other PDF merging tools. The developer leveraged iTextSharp, a widely respected open source PDF library, to ensure reliable PDF handling and output. The result is a clean and easy to use application that focuses entirely on merging PDF files without modifying their content.
The interface is intentionally simple, making it accessible even for less technical users. Files can be added to the list, reordered using built in controls, or removed entirely before starting the merge process. Because it only works with unlocked PDFs, the program avoids complications related to encrypted or password protected documents.
