Buat PDF Pindaian Dapat Dicari dengan OCR

Our OCR engine achieves over 99% accuracy on clear, high-resolution scanned documents with standard fonts. Accuracy depends on the quality of the original scan, the clarity of the text, and the font type used. Clean scans of typed documents in common fonts (Arial, Times New Roman, Calibri) produce excellent results. For best accuracy, scan documents at 300 DPI or higher in black and white or grayscale mode.

OCR works best with typed or printed text. Handwritten text recognition has lower accuracy because handwriting varies significantly between individuals. While the engine can detect some handwritten content, it is not recommended for critical documents where perfect transcription of handwriting is required. For typed documents, forms, and printed materials, the accuracy is excellent.

After OCR processing, your PDF becomes fully searchable and selectable. You can search for specific words or phrases using your PDF reader's search function (Ctrl+F or Cmd+F). You can also copy and paste text from the document into other applications. The visual appearance of the scanned page is preserved — a hidden text layer is added underneath the scanned image, making the text accessible without changing how the document looks.

Yes. All OCR processing happens entirely in your browser using client-side WebAssembly. Your scanned document is never uploaded to any server. This is particularly important for sensitive documents like medical records, legal documents, or personal identification that you want to make searchable without compromising privacy.
