Questions before you run it
What does PDF Image Inventory actually inspect or change?
The processor groups image resources by PDF cross-reference and records every page that references each one. It processes only the supported structures found in the selected PDF and returns a separate download. It does not overwrite the source, infer missing document intent, or certify legal, archival, accessibility, privacy, or security status. Review the artifact against the original before using it in another workflow.
What limits apply to PDF Image Inventory?
One unlocked PDF containing at least one embedded image resource. The request is limited to 10 MB, the document to 500 pages, discovered structures to 10,000 items, and generated output to 50 MB. Password-protected files must be unlocked first. Malformed, application-specific, or unsupported PDF objects may require a specialist desktop application and manual inspection.
What should I verify after PDF Image Inventory finishes?
Confirm the download opens and matches the stated output, then compare page count, visible content, navigation, form behavior, and any task-specific structure with the source. Vector drawings, masks, inline edge cases, and effective placed resolution need separate visual analysis. Keep the original until the result has been tested in the viewer, print process, records system, or downstream application where it will be used.
