Lines come out in reading order rather than jumbled together, so you can paste the result somewhere and it still makes sense.
The PDF reader loads only when you drop a file in, so the page itself stays light. Your file is read on your own machine and never sent anywhere — open your browser's network tab and watch while you use it.
No, and it says so instead of handing you an empty file. A scan is a picture of text with no text layer inside — that needs OCR, which is what our statement tool does.
Line breaks are, columns are not. It is meant for getting at the words, not for rebuilding the page.
Everything here is free and works the same way — in your browser.
