Details

How this works

Check OCR readiness

Choose a PDF to see whether it looks scanned, mixed, rotated, or already digital before using OCR.

Input 
document.pdf
Output 
Verdict, OCR candidate signals, scan-routing steps, verification checks, and limitations
Edge cases
  • Mixed digital/scanned PDFs may need both PDF to Text and OCR review instead of one blanket workflow.
  • 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 does not run OCR. It helps decide whether PDF OCR or PDF to Text is the better next step.
  • 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 OCR Readiness Checker

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 run OCR, repair scans, detect every language, or promise recognition accuracy.

Workflow fit

Use OCR Readiness Checker 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 ocr-readiness-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.

PDF Image Density Report

Execution depth

Finish the job with fewer retries

Use these checks when the result will be emailed, uploaded, published, imported, or used as a final handoff copy.

Good uses

  • Decide whether a scanned PDF is worth sending to OCR.
  • Check rotation, image-density, and text-layer signals before PDF OCR.

Bad inputs

  • Expecting OCR output from the checker.
  • Using it to correct scan quality.
  • Skipping review when the OCR result will be reused in a formal document.

Output checklist

  • Confirm OCR is needed instead of text extraction.
  • Review likely blockers before running PDF OCR.
  • Plan a manual check of names, totals, dates, and line breaks.

Failure modes

  • Low contrast and rotated scans can still produce weak OCR.
  • Language and handwriting issues require manual review.
  • Readiness signals do not predict every OCR error.

Runtime limits

  • Browser-local checker.
  • No OCR is run.
  • Use before server-backed OCR when quality matters.
