अक्सर पूछे जाने वाले प्रश्न
How long does it take?
Typically 3 to 15 seconds per page on a computer and longer on a phone or an old device. Use 150 dpi for speed and 300 dpi for small print. Keep the tab open while it works.
Which languages are available?
English, Italian, German, French, Spanish, Portuguese and Dutch. The language data (a few MB) is downloaded from this site only when you start, then it is cached by your browser.
How accurate is it?
Clean, straight scans of printed text are recognised very well. Handwriting, photos taken at an angle, low-contrast or decorative text give worse results. Always check important numbers.
What does the searchable PDF contain?
Each page becomes a picture of the original page with an invisible text layer on top. It replaces the original text and graphics of those pages, so keep your original file.
Is anything uploaded?
No. The recognition engine and the language data are loaded from this site and run in your browser.
