Frequently Asked Questions

What is PDF preflight inspection?

PDF preflight is a diagnostic process that analyzes a PDF file's internal dictionary, structural integrity, embedded fonts, page bounding boxes (MediaBox, CropBox), and metadata to flag discrepancies before commercial printing or publication.

Can this tool detect mixed page sizes within a single document?

Yes. The preflight inspection analyzes every page individually, reporting exact point and millimeter dimensions so you can instantly identify irregular landscape pages or sizing errors.

Is my document analyzed privately?

Yes. SolversPro runs the preflight inspection entirely within your browser's local sandbox memory. No file contents or metadata are ever transmitted across the network.
