FAQ

Common questions

Optical Character Recognition (OCR) analyzes the pixel patterns of scanned letters and numbers, translating visual shapes into machine-readable text characters. The tool then overlays an invisible, aligned text layer directly on top of the original page image. This allows you to highlight text, copy paragraphs, and search for specific keywords using standard PDF viewers.
Documents scanned at 300 DPI (dots per inch) with good contrast between text and background yield the highest character recognition accuracy. Low-resolution scans below 150 DPI, skewed pages, or heavily handwritten documents may experience recognition errors. Straightening scanned pages and ensuring adequate lighting during scanning significantly improves results.
Yes, in addition to creating a searchable PDF file, the tool provides a dedicated text extraction tab where all recognized characters appear in an editable text box. You can review the output, correct formatting, and copy the text directly to your clipboard for use in word processors.
Character recognition is carried out directly in your browser using client-side OCR libraries without uploading your scans to remote web servers. Because all pixel analysis and document generation occur locally on your machine, your private financial figures, medical records, and legal contracts remain strictly on your device.
