Frequently Asked Questions
OCR (optical character recognition) reads the text in a scanned PDF and adds an invisible text layer, so you can search, select and copy the text.
The OCR engine is Tesseract and English is the default. Choose the document language in the tool for the best accuracy.
Use clean, straight scans and a higher DPI setting (300 DPI is a good default). Low-resolution or skewed scans reduce accuracy.
You can upload PDFs up to 50 MB.
