Merge PDF Files

This tool merges multiple PDF documents into a single output file. It supports any number of input PDFs up to platform limits and aims to preserve fonts, images, and layout as produced by the source files. The result is a consolidated document suitable for sharing, archiving, or review. It operates without modifying the content beyond concatenation and preserves metadata when available, so bookmarks and document properties remain meaningful in the merged file.

Conceptually, pages from each input are concatenated in the specified order. For each input you may apply per-file page ranges to include only portions of a source, and the merged file will reflect those selections. If a source provides bookmarks or metadata, the tool attempts to retain them in the merged output; if not supported, metadata may be omitted.

Target users include legal teams compiling contracts, finance teams consolidating statements, educators assembling course materials, researchers curating reports, and operations teams sharing client portfolios. The unique value is robust handling of mixed-source PDFs, reliable page-range processing, and a single output file that simplifies distribution and reduces the risk of mismatched attachments.

Core features and behaviors include multi-file input, explicit ordering, optional per-file page ranges, optional bookmark and metadata retention, and support for encrypted inputs when passwords are supplied. Outputs include a single merged PDF along with computed totals (pages and file size) to facilitate downstream processing and validation. For sensitive materials, the tool adheres to platform privacy practices and processes data with transient storage.
