Workflows

Scan to Searchable PDF

This workflow describes how to convert paper documents into PDFs whose text can be searched, by combining a quality scan with optical character recognition.

By PrinterArchive EditorialEdited by PrinterArchive Editorial

A plain scan produces an image of a page. To make the document genuinely useful for archiving and retrieval, the text within that image must be recognised so it can be searched. This workflow is deliberately generic and not tied to any specific product.

  1. Prepare the document

    Remove staples, flatten folds, and order pages so the scan reflects the intended sequence.

  2. Scan at an adequate resolution

    Use a resolution high enough for reliable text recognition while keeping file size reasonable. Clean, high-contrast scans recognise more accurately.

  3. Apply OCR

    Process the scan with OCR-capable software so an invisible text layer is added beneath the page image.

  4. Verify and save as PDF

    Spot-check that text can be selected and searched, then save as a PDF so appearance and searchable text are preserved together.

Frequently asked questions

Does every scan become searchable automatically?
No. A scan is an image until OCR is applied. Without OCR the document looks correct but its text cannot be searched.
