What to expect
Each recognizer has up to 90 seconds. English, Russian and mixed models are available. OCR may misread letters, numbers and reading order; check important values. This tool processes images, not complete PDF documents.
Text output is limited to 1 MB per recognizer.
The first run may download converter files and take a moment. If it fails, check your connection or try a smaller file. Cancel stops active processing; you can choose another file and retry.
