1. Copy the text from the PDF and paste it into Word.
  2. After you copy the text there should be a little icon of a clipboard and piece of paper that you can click next to the last word that you copied. If you hover your mouse over this button it reads, "Paste Options"
  3. Click the button and select, "Match Destination Formatting".
  4. Click "Format", and then select "Auto Format". A window should pop up.
  5. Make sure "Auto format", and "general document" are selected and then click "ok".

Now copy the text into the LingQ text box like you normally would.
