Why Choose Our PDF OCR Service?
Scanned and image-based PDFs store text as raster pixel arrays rather than searchable character streams. ForgeFile's PDF OCR engine parses the PDF page tree, extracts embedded bitmap images (including CCITT Fax, JBIG2, and FlateDecode streams), and performs optical character recognition aligned with ISO 32000 specifications.
The resulting document embeds an invisible, selectable OCR text layer directly behind the original scan images, enabling Ctrl+F full-text searching, text selection, and copy-pasting while keeping the visual layout completely unchanged.
PDF Architecture Handled by OCR
- Pure raster PDF scans - PDF containers enclosing scanned document images without an existing text stream.
- Mixed vector and raster pages - Documents with selectable digital text on some pages and image scans on others.
- Multi-page document trees - Sequential recognition across multi-page document catalogs, preserving page order and bookmarks.
- Rotated and skewed pages - Automatic page orientation and deskew detection before character segmentation.
Searchable PDF & Document Deliverables
- Invisible text overlay - Generates searchable PDF files with glyph bounding boxes aligned to underlying scan coordinates.
- Editable Word DOCX - Reconstructs paragraph flow, tables, and typography into native editable Microsoft Word format.
- Structured table retention - Identifies tabular cell boundaries for financial statements and reports.
- The maximum file size depends on your plan.
- Encrypted processing - Files are encrypted in transit and at rest.
The PDF 2.0 file format specification is documented by the Library of Congress digital format sustainability project.

Frequently Asked Questions - PDF OCR
What types of PDFs work with PDF OCR?
Scanned PDFs, image-based PDFs, and mixed PDFs (combining selectable and scanned pages) are all supported. Native text-selectable PDFs are passed through without OCR and returned as-is.
What output formats are available?
Searchable PDF (original appearance with invisible text layer), editable DOCX (Word-compatible with formatting preserved), and plain TXT.
How accurate is PDF OCR?
Scan resolution (300 DPI recommended), skew angle, and contrast directly affect recognition accuracy. Faded text or severe compression artifacts may require manual verification.
Can it extract data from tables in scanned PDFs?
Yes. Table detection identifies rows, columns, and cell boundaries. Tables are reproduced in the output DOCX as editable Word tables, or exported to CSV on request.
What languages are supported?
14+ languages: all Latin-script European languages, Cyrillic (Russian, Ukrainian, Bulgarian), Arabic and Farsi (RTL), Hebrew, Chinese (Simplified and Traditional), Japanese, Korean, Greek, Thai, Hindi (Devanagari), and more.
Is my PDF kept private?
Files are encrypted in transit and at rest. How long they are kept depends on your plan.
