Information guide

PDF upload preflight metadata checks

Understand which local PDF metadata, page-size, file-size, and page-count details should be checked before upload or delivery.

Quick answer

The practical starting point

Confirm that you selected the correct PDF, then compare page count, page dimensions, and file size with the destination's requirements. Mixed page sizes or an unexpected count are reasons to stop and inspect the document visually.

What this guide explains

Learn which PDF file details to inspect before using a PDF checker.

File size, page count, and page dimensions are quick signals that the wrong PDF may have been selected.
Metadata checks are useful before delivery, but they do not replace print proofing or visual review.
A local PDF check keeps the file private while still producing a handoff note or review report.

Use metadata as a fast mismatch detector

Page count, dimensions, and file size are useful because they can reveal the wrong export before upload. A one-page file where twenty pages were expected, a mixed-size document, or a dramatic size change should trigger review. Record the observed values with the filename so another person can reproduce the check.

Compare the detected page count with the source document.
Check whether all pages share the required trim or canvas size.
Investigate unusually small or large files rather than assuming compression is harmless.

Know what metadata cannot prove

A browser metadata check does not prove that fonts are embedded, images have enough effective resolution, colors are correct, bleed is present, links work, or the pages render as intended. Open the final PDF in a trusted viewer and follow the printer, marketplace, or client preflight requirements.

Inspect every page after conversion or compression.
Use a print proof or specialist preflight for production work.
Keep private or sensitive PDFs local and remove unnecessary metadata before sharing when required.

FAQ

Does this replace print proofing?

Use it as a quick local preflight for page count, page size, and file size before deeper print checks.
