Make scanned pages searchable
OCR recognizes text in scanned or image-based PDF pages and adds machine-readable text so recognized words can be searched.
Make scanned PDFs searchable with OCR
Convert a scanned PDF to a searchable PDF
Add machine-readable OCR text to an image-based PDF so you can search and select recognized text while keeping the result as a PDF document.
No subscription required. Files are not stored permanently.
Add searchability without changing the job
Keep the PDF and make its scanned text usable
This workflow is for PDFs whose pages are images or scans and need OCR text for searching and selecting while remaining PDF documents.
Keep the result as a PDF
The goal is a searchable PDF, not a Word document or plain-text extraction, so the document stays in PDF form for the next workflow.
Understand where OCR errors can enter
OCR works from the visual information in the scan. Poor focus, low contrast, rotation and degraded originals can reduce recognition accuracy.
Review recognized text that matters
Names, numbers, dates and other important content should be checked after OCR because searchable text can contain recognition errors even when the page image looks unchanged.
From scanned PDF to searchable PDF
Add OCR in three steps
Use FilexFlow’s existing PDF to Searchable PDF workflow and review the OCR result before relying on recognized text.
-
1
Upload the scanned or image-based PDF
Choose the existing PDF whose visible text cannot be searched or selected normally.
-
2
Run PDF to Searchable PDF
Select the OCR workflow and review the estimated credit use before processing.
-
3
Download and check the searchable PDF
Download the generated searchable PDF and test important recognized words, names or numbers before using OCR text in a critical workflow.
When a PDF looks readable but its text is not searchable
Useful reasons to add OCR to an existing PDF
The page owns the conversion of an existing PDF into a searchable PDF; deeper OCR preparation and troubleshooting belong in the Guides.
Scanned records
Make a scanned document searchable
Add a searchable text layer when an existing scanned PDF must remain a PDF but you need to find recognized names, phrases or reference numbers.
Make a scanned PDF searchableOld or poor scans
Set realistic expectations for difficult source pages
Older, faint, skewed or degraded scans can produce weaker OCR. Review source quality and important recognized text before depending on the result.
Improve OCR on old or poor scansOCR review
Check recognition errors before relying on text
Searchability does not guarantee that every character was recognized correctly. Review high-value text such as names, dates, identifiers and numbers.

Searchable PDF and OCR questions
What to know before relying on OCR text
A searchable PDF adds machine-readable text to scanned content, but OCR quality still depends on what can be recognized from the source pages.
What makes a scanned PDF searchable?
OCR analyzes the visible page image and creates machine-readable text associated with recognized content, allowing supported PDF viewers to search recognized words.
Does PDF to Searchable PDF turn my document into Word?
No. This workflow keeps the output as a PDF. If the actual goal is an editable Word document, PDF to Word OCR is a different workflow.
Will OCR recognize every word perfectly?
No perfect recognition guarantee is made. Scan quality, contrast, orientation, typography and source degradation can affect OCR accuracy.
Why can a PDF look correct while searchable text contains an error?
The visible scanned page and the OCR text are different layers of information. The page image can still look correct even when OCR misreads a character or word.
What should I check after making a PDF searchable?
Search for important names, dates, numbers or phrases and verify recognized text against the visible page when accuracy matters.
