How should I interpret PDF analysis results?

You get a simple binary answer: the PDF has been modified (yes) or it has not (no). Our system uses an internal confidence score (0-100) to produce this result; you do not need to interpret the number yourself.

On the result page you also see detailed metadata (creation date, modification date, creator, producer) and structural findings (e.g. incremental updates, xref anomalies). These help you understand why the service gave a yes or no. If the result seems unexpected, consider the PDF’s creation workflow and whether any modifications were authorized.

For important decisions, use this yes/no result as part of a broader verification strategy rather than the sole factor.
