Common Questions Answered

Quick help
Q1 How accurate is the local OCR scanner?
It provides very high accuracy on clear documents. Actual recognition performance depends on the scanned PDF resolution and image contrast.
Q2 Does it support multi-language documents?
Yes, you can select multiple dictionaries simultaneously to recognize mixed-language text strings in the same scanned file.
Q3 Can I run OCR on password-protected files?
You will need to input the user password to unlock the document canvas before the OCR engine can read and analyze the pages.
Q4 Is there a page count limit for recognition?
No limits are set, but scanning very large books client-side might consume more system memory and execution time.
Q5 Are my scans or texts uploaded to any external servers?
Absolutely not. All optical character recognition is performed locally within your browser sandbox. No file leaves your computer.
