How this works

Report PDF scan quality

Choose a PDF to inspect scan-related signals like image objects, rotations, mixed page sizes, and compression markers before OCR.

Input 
document.pdf
Output 
Verdict, scan quality warnings, OCR preparation steps, verification checks, and limitations
Edge cases
  • Low-contrast, rotated, fax-compressed, mixed-size, or tiny-text scans can produce weak OCR.
  • Encrypted, malformed, or unusually compressed PDFs may fail before a complete report is created.
  • Marker counts can overcount repeated references or miss details hidden inside compressed objects.
Accuracy
  • This is not OCR and does not enhance scans. It highlights quality risks before processing.
  • Use the verdict as routing guidance, not as a guarantee.
  • Review the final output after any OCR, compression, cleanup, or conversion step.
Privacy
  • The PDF is inspected locally in your browser for this report.
  • Telemetry avoids raw filenames, file contents, extracted text, and report output.

Guide

How to use PDF Scan Quality Report

Step-by-step

  1. Choose an unlocked PDF from your device.
  2. Run the report and start with the Verdict section.
  3. Review Signals before following the Recommended next actions.
  4. Use the Verification checks section before sharing, uploading, OCRing, or converting the file.

Questions

Are my files uploaded or changed?

No. This is a read-only browser-local report. Use a separate cleanup, OCR, compression, or conversion tool when you decide what needs to happen next.

What should I do with a needs-review result?

Follow the recommended next actions, then verify the final output with the suggested checks before using it as a handoff copy.

Can this prove the file is safe for regulated use?

No. It does not improve scan quality, run OCR, or guarantee confidence scores.

Workflow fit

Use PDF Scan Quality Report in the right place

If you are unsure, start from the PDF chooser and pick by task: inspect, organize, compress, convert, print, compare, or flatten.

Best for

  • PDF workflows where page order, hidden document signals, output size, or final sharing quality matters.
  • Preparing a review, upload, print, or archive copy without turning the page into a generic article detour.
  • A focused inspect task where the expected output is scan-quality-report.

Before you start

  • This tool runs in the browser, so keep the tab open until the result is created and downloaded or copied.
  • Keep an original PDF copy outside the workbench before creating edited, flattened, compressed, or converted outputs.
  • If the document has passwords, unusual permissions, forms, annotations, or scripts, inspect those signals before finalizing a sharing copy.
  • Finish page-order changes before adding page numbers, watermarks, compression, or other final-copy operations.
  • Use the report as a decision aid, then route to cleanup, conversion, or verification tools if it finds something notable.

Quality checks

  • Treat inspection output as a signal report, not as a guarantee that every possible issue was checked.
  • Open the output PDF in a reader after processing; PDF structure can change even when the visible pages look similar.
  • Check page count, page order, orientation, metadata, and file size against the actual destination requirement.
  • Use checksums when the exact final copy needs to be referenced later.
  • Copy or download the result only after confirming the displayed output matches the task you intended.

Common mistakes

  • Compressing a PDF before deleting, extracting, or reordering pages creates extra throwaway versions.
  • Assuming visible page content is the whole document misses metadata, links, attachments, actions, annotations, and permissions.
  • Using text extraction on scanned pages will not create OCR text. Treat no-text results as a scan signal.
  • Closing the tab before downloading or copying a browser-generated result.
  • Treating the first result as final without checking the destination requirement.

Verify or clean up

Use these when the output needs checking, cleanup, comparison, compression, or a final share-ready pass.
