A user of the PDF24-Merge tool is having difficulties reviewing the merged PDF document before final download. Despite the tool's stated functionality of providing the user with a checking option before creating the final version, the user is encountering a issue. This complicates the process, as the user cannot ensure that all documents are arranged in the desired order or that there are no errors in the merging. Since the review is one of the tool's notable features, the lack thereof creates a significant inconvenience. This problem requires an immediate solution, especially since the user has no way to correct errors after downloading or make changes to the compilation.

The PDF24 Merge Tool can address the user's issue by providing a preview option before the final document is created. With this feature, the user can verify the order of the PDFs and make adjustments before the final document is downloaded. The intuitive user interface and drag-and-drop functionality aid this process and allow for easy corrections. A preview of the merged document ensures there are no errors in the merge and all files are sorted correctly and in the desired order. With this feature, the user can ensure that the final document meets their requirements before downloading it. Furthermore, the revised and finalized document will retain the quality of the original files. All these features are offered to the user for free and without the need for registration.
