How to use PDF Print Checker
- Choose one PDF within browser safety limits.
- Review every measured fact and unknown limitation.
- Use a linked existing tool only when a supported finding needs action.
PDF Print Checker
Review page consistency, rotation, raster DPI, font embedding, parser-reported protection, and explicitly unknown press checks.
The PDF and diagnostic facts stay in browser memory. The source is not modified, uploaded, or saved, and embedded actions are never executed.

Review page consistency, rotation, raster DPI, font embedding, parser-reported protection, and explicitly unknown press checks. Results are evidence-based, and any fact the current parser cannot establish remains labeled unknown.
How OpenFileTools processes it
Local processing, explicit choices.
The managed PDF.js session reads searchable-text fonts, page geometry, and image-paint operators in memory. Reused raster placements are measured independently at their displayed size. Embedded actions are never executed.
Questions, answered.
Is my PDF uploaded?
No. PDF bytes and diagnostic results stay in this browser tab.
Does this change the PDF?
No. These diagnostics are read-only.
Why does a check say unknown?
OpenFileTools reports unknown instead of guessing when the browser parser does not expose reliable evidence.
