📌 Why this matters

Comparing PDFs catches changes that would otherwise slip through manual review, especially in legal documents, contracts, or technical specifications where a single altered word can have major implications.

You can spot subtle modifications like updated clauses, shifted numbers, or deleted sections without reading entire documents side-by-side. This becomes particularly valuable when reviewing document versions from different stakeholders, as people often make changes without highlighting them or providing clear change logs.
