How to Find Bad Pages in a Scanned PDF Before You Send It
2026-10-11 · themgdev team
A long scanned PDF can look fine at first glance and still contain one empty page, the same sheet twice, a faint receipt or a sideways page in the middle. Those mistakes usually surface only after the file has been sent, printed or archived.
PDF Scan Doctor checks every page in one pass and produces a page-by-page audit without uploading the document.
What the scan check looks for
- Likely blank pages with almost no visible ink.
- Duplicate pages with the same visual fingerprint.
- Blur and low contrast that may make text hard to read or OCR.
- Possible skew from a page going through the scanner at an angle.
- Rotation problems and pages whose size or orientation does not match the rest.
How to check a scanned PDF
- Open PDF Scan Doctor.
- Add the scanned PDF you want to inspect.
- Choose whether to remove likely blank pages, remove later duplicate copies, or correct explicit 180-degree rotation metadata.
- Click Check and clean PDF.
- Review the findings on screen, then download the cleaned PDF and HTML audit report.
Why blur and skew are reported instead of silently fixed
Removing a clearly empty page does not affect the pages you keep. Sharpening, boosting contrast or deskewing is different: it normally rebuilds the page as a new image and can reduce quality, remove selectable text or make a faint original look worse. The doctor flags those pages so you can inspect them and rescan the source when that is the better answer.
Keep the audit with important records
The downloadable report lists every page, its findings and its page size. For a case file, invoice batch or records archive, that gives you a simple quality-control record and a direct list of pages that may need to be captured again.
Is the scan uploaded?
No. The PDF is rendered, checked, cleaned and packaged in your browser. Confidential documents stay on your device.
