PDF File Merger

This tool implements PDF merging in Python by reading input PDFs in a specified order, applying optional page ranges, and writing a single output file. It focuses on automation, reproducibility, and metadata preservation.
Core workflow uses a standard PDF library (e.g., PyPDF2/pypdf) to append pages from each input. Page ranges are parsed as start-end or single indices, inclusive. The tool validates inputs and reports any corrupt or password-protected files.
Who benefits: developers automating report compilation, researchers assembling literature sets, QA teams blending test documents, and IT ops integrating into pipelines. Unique differentiators include robust error handling, configurable merge order, and preserved metadata.
Outputs include the path to the merged file, file size, and a log of actions. Optional features such as preserving bookmarks or adding timestamps can be extended in pipelines.
