Underline text in a Microsoft Print to PDF file

Underline words, or remove an underline, straight in the PDF. PDFs made with Microsoft Print to PDF often have no real text, only drawn letter shapes. MythosPDF turns them back into text first, so this works on them too.

What that means when you underline text

  • • Formatting applies to the recovered text exactly as it would in a PDF that was saved with fonts.
  • • After export, the recovered text can be selected, copied and searched, which the printout could not do.

How Microsoft Print to PDF writes the PDF

  • • Depending on the app and the fonts, Microsoft Print to PDF either embeds the fonts or draws every letter as a filled shape.
  • • When letters are drawn as shapes, the PDF has no text at all: you cannot select, copy or search anything on the page.
  • • Letters are placed one at a time in printer units, inside a flipped page transform.
  • • Thin letters such as l, i and I, and the dots of punctuation, are often collected from many lines into one shape drawn later.

How MythosPDF makes a Microsoft Print to PDF file editable

  • • The page is read with OCR, then every word is matched to the letter shapes that draw it.
  • • Letters are grouped into fonts by their outlines and size, so bold, regular and heading text stay apart.
  • • The typeface is identified from letter widths and shapes, and each line gets its real baseline.
  • • The page is rebuilt with text fonts made from the document's own letter outlines, so it looks exactly as printed.
  • • Every rebuilt letter is checked against the original position, and the page is compared pixel by pixel before you edit.

What happens to the rest of the page

  • • The underline follows the text's colour and position.
  • • Underlines move with their words when text reflows.

Questions people ask

+Why can't I select text in my Microsoft Print to PDF file?

The driver often draws every letter as a shape instead of writing text. MythosPDF reads those shapes and turns them back into real text before you edit.

+Will the page look different after recovery?

No. The rebuilt text uses the document's own letter outlines, and every page is compared with the original before you edit.

+Can I remove an underline?

Yes. Select the words and press U again.
