AI-powered OCR

Not just pattern matching — our AI understands document layout, handles mixed text orientations, and recognises text in complex backgrounds.

✍️

Handwriting supported

Extracts clear block printing and typed handwritten notes. Accuracy depends on legibility — printed text achieves 98–99% accuracy.

📷

Phone photos work

Take a photo of a document with your phone camera and upload directly. As long as the image is in focus and well-lit, extraction is highly accurate.

🌍

Multi-language OCR

Supports all major Latin scripts, Cyrillic, Arabic, Chinese, Japanese, Korean, Hindi, and Greek — with automatic language detection.

What Is OCR and Why Does It Matter?

OCR (Optical Character Recognition) converts images of text into actual, selectable, searchable, editable text. Before OCR, a scanned document was just a photograph — you couldn't search it, copy from it, or feed it to any text processing system.

AI-powered OCR (what we use) goes further than traditional OCR libraries: it understands document layout, handles multiple text orientations, and recognises text in complex backgrounds and mixed-language documents.

Supported Input Types

  • Scanned PDFs — PDFs where every page is an image (no selectable text)
  • Photos of documents — taken with a smartphone camera
  • Screenshots — from any source (desktop, browser, app)
  • JPG, PNG, TIFF, WebP images — single-image files
  • Handwritten notes — clear block printing extracts well; cursive is partially supported

Factors That Affect Accuracy

  • Resolution (DPI) — 150 DPI minimum, 300 DPI recommended. Phone camera photos at full resolution are typically sufficient.
  • Lighting — even lighting with no shadows across text. Glare from glossy pages can reduce accuracy significantly.
  • Angle — documents photographed at an angle (keystoning) produce lower accuracy. Photograph straight-on or use automatic perspective correction.
  • Font — standard printed fonts: near-perfect accuracy. Decorative, cursive, or heavily stylised fonts: reduced accuracy.
  • Background complexity — text on plain backgrounds extracts perfectly. Watermarked, patterned, or coloured backgrounds reduce accuracy.

After Extraction: Recommended Next Steps

  • Check grammar — OCR occasionally introduces errors in similar-looking letters (I/l/1, O/0). Run through Grammar Check to catch these.
  • Extract structured data — if the image contained tables or forms, useExtract Data for structured CSV/JSON output.
  • Translate — extracted text from foreign-language documents can go directly into our Translate PDF tool.
  • Create a searchable PDF — use AI Chat with PDFon your original scanned PDF after confirming text quality with the OCR extraction.

JPG, PNG, TIFF, WebP, and PDF (scanned). Multi-page PDFs are processed page by page.

For clean printed text, accuracy is typically 98–99%. Blurry or low-resolution scans will reduce accuracy — use at least 150 DPI for best results.
