What Is OCR and Why Do You Need It?
OCR (Optical Character Recognition) is technology that converts images of text into actual, selectable, editable text. If you've ever received a scanned PDF where you couldn't select or search the text — that's a document that needs OCR.
Scanned PDFs are essentially photographs of pages. The text looks like text to your eyes, but to a computer, it's just pixels. OCR analyzes those pixels and identifies the letters, words, and sentences, converting them back into real digital text.

What OCR Can Do
Extract Text from Scanned Documents
Turn image-based PDFs into searchable, selectable text. Perfect for scanned contracts, old documents, and paper records.
Extract Text from Images
Pull text from photos of documents, screenshots, or image files. Great for capturing text from signs, labels, or printed materials.
Make PDFs Searchable
After OCR, you can search within the document for any word or phrase — no more scrolling through 50 pages to find one sentence.
Convert to Editable Formats
Once text is extracted, you can convert it to Word, Excel, or plain text for editing.
OCR Accuracy — What to Expect
Modern OCR is highly accurate for:
- Printed text — 98–99% accuracy for clean, high-resolution scans
- Standard fonts — Excellent recognition of common typefaces
- Multiple languages — Supports English, Spanish, French, German, and many more
Accuracy may be lower for:
- Handwritten text — Depends on legibility
- Low-quality scans — Blurry or skewed images reduce accuracy
- Unusual fonts — Decorative or stylized fonts are harder to recognize
- Complex layouts — Multi-column or table-heavy documents may need manual review
Tip: For best results, start with the highest-quality scan possible. The Smart Scanner tool can help you capture clean, high-resolution scans using your phone camera.
