How to Extract Text from a Scanned PDF
Learn how to recognize scanned PDF pages, review layout-aware output, and export useful text with OmniOCR.
A scanned PDF often contains page images instead of selectable text. Copy and search may fail even though the document looks normal on screen. OCR reads those page images and creates editable output.
Check the file first
Try selecting a sentence in your PDF viewer. If no text can be selected, or the selection is incomplete, OCR can help. OmniOCR accepts PDF files up to 10 MB.
Encrypted, damaged, or unusually complex PDFs may fail to process. Removing a password or exporting a clean copy before uploading can improve reliability.
Recognize the PDF
- Open the OmniOCR workspace.
- Upload the PDF; no sign-in is required.
- Keep the file selected while processing finishes.
- Compare the result with the original preview.
OmniOCR returns Markdown and, when the provider detects them, separate table, formula, and page-layout data. The reported page count also helps you confirm that the full document was processed.
Clean up the output
Review page breaks, headings, figures, footnotes, and multi-column reading order. Dense tables and mathematical notation deserve a second check. Copy a specific result view or download the extracted content for further editing.
The PDF is sent to the OCR provider only to perform recognition. OmniOCR does not store the source PDF or extracted text in its application database. Recent result text may remain in your browser until you clear local history.
