Upload a scanned or image-based PDF and extract readable text with Tesseract OCR in your browser. Review the combined text and download a .txt file. Up to 20 pages; accuracy depends on scan quality.
OCR adds a searchable text layer to scanned pages so you can copy, search, and sometimes reflow content. Accuracy depends on scan resolution, skew, handwriting, and language. Always proofread numbers, names, and legal citations extracted from OCR output.
Processing runs in your browser with Tesseract.js—your PDF is not uploaded to Utilnivo servers. Low-contrast faxes and phone photos may need rescanning at 300 DPI or higher before OCR will perform well.
Multi-column newspaper layouts may read columns out of order—use Extract PDF Pages to OCR one section at a time when structure matters.
For forms you plan to fill digitally, OCR the scan first, then run PDF to Word only if you need to edit field labels—not every OCR output reflows cleanly into Word.
Skewed phone photos of documents should be deskewed in a scanner app before OCR—rotation errors propagate into jagged text lines that confuse recognition.
