PDF Merger

The tool consolidates PDFs into a single document while preserving the original page order. It targets professionals in legal, finance, education, and operations who need to produce client-ready bundles, reports, or contracts. It accepts an arbitrary number of input PDFs, validates each file as a valid PDF, and outputs a single merged document. The merging process is deterministic: the user defines the exact order of inputs and can optionally specify which pages from each input should be included. The result maintains the fidelity of text and images, with no OCR, reflow, or watermarking unless explicitly requested by custom options.
Conceptually, the tool loads each input PDF, applies per-file page ranges when provided, and appends the included pages to a new output stream in the specified order. It preserves bookmarks and metadata when supported by the underlying PDF libraries, ensures proper pagination, and avoids altering content. It runs in-session without permanently storing documents, and the final output can be downloaded immediately or exported to a cloud location if the user chooses. Performance safeguards limit total input size to prevent timeouts and ensure reliability.
Use cases include compiling project reports, legal bundles for review, academic packets for submission, or client deliverables requiring a single file. The tool differentiates itself with precise per-file range handling, non-destructive merging, predictable output, and a lightweight processing model that supports reproducible results across platforms.
