Scan Quality Checklist for Multi-page PDFs
Use a consistent capture workflow and then review every page. Automated scan warnings help prioritize inspection but cannot replace checking the document itself.

Quick checklist
Use the checklist as a starting point, then follow the instructions of the receiving website or organization. Save your original before editing.
Get the source scan right
Place each page flat against a contrasting background and use even lighting without a strong shadow across the text. Keep the camera parallel to the page whenever possible. A document scanner is useful for batches because it offers more consistent focus and framing than hand-held photos.
Look closely at faint pencil marks, seals, signatures and fine printed tables. These are often the first details to disappear when a scan is too dark, too light or overcompressed.
Inspect the complete PDF
Open the finished PDF and compare its page count and sequence with the source document. Look for accidentally scanned blank backs, duplicate sheets, rotated pages and clipped corners. Scan Quality Checker can flag visually unusual pages and provide a CSV report.
Treat the checker's brightness, contrast, sharpness and skew values as indicators rather than standards. A nearly blank legal page could be intentional, and a photograph in the document may skew the visual metrics. Visually review the output at normal zoom before making any deletion.
Fix only confirmed problems
If a page is genuinely blurred, rescan it instead of relying on artificial sharpening. If it is sideways, use Rotate PDF. If the PDF contains unwanted scanner duplicates, Smart PDF Cleaner can suggest pages, but you should select removals only after comparing names, dates and signatures.
Use PDF Page Size Analyzer when printing or a receiving portal requires uniform paper size. A PDF with one Letter page in an otherwise A4 stack can print with inconsistent margins.
Final submission check
Open the downloaded final PDF in a second viewer and check the first, middle and final pages as well as every page that was flagged. Confirm that all attachments and required signed pages remain. Store the unchanged original in case you need to repair or recreate the submission.
Common situations and next steps
| Situation | Suggested next check |
|---|---|
| Blank-looking page | Compare it with the source; pale stamps or a short note can look empty in a thumbnail. |
| Low contrast | Rescan with consistent lighting; inspect fine print and handwriting. |
| Possible skew | Look for tilted text lines and check if it affects legibility. |
| Unexpected paper size | Check the destination's format instructions and the PDF Page Size Analyzer report. |
