COMMON QUESTIONS

Frequently Asked Questions

Optical character recognition setups decoded
? What is PDF OCR?
OCR stands for Optical Character Recognition. It is a process that translates rasterized page images and pixels of text into selectable, searchable computer text.
? Are my private scanned documents or contracts uploaded online?
No. The character recognition libraries load and execute inside your browser sandbox. Your images and documents never leave your computer.
? How accurate is the local character recognition engine?
High-contrast scanned text yields up to 98% accuracy. Accuracy decreases slightly on handwritten notes, crumpled papers, or low-resolution faxes.
? Which languages are supported?
Our client-side engine supports English, Hindi, Spanish, French, German, Chinese, and dozens of other dictionary packages.
? Can I download the raw text instead of a PDF?
Yes. You can extract the text directly into your clipboard, download it as a plain-text file (.txt), or save it as a structured PDF.
? Why does processing large PDFs take longer?
Because image analysis is computationally expensive. The client-side OCR engine analyzes pages sequentially, which depends on your device's CPU.
