Make a scanned PDF searchable in a research paper printed to PDF
Last minute fixes to your own paper, like an author affiliation, a typo in a heading or a corrected figure caption, can be made directly in the PDF you're about to submit. If it was printed with Microsoft Print to PDF, the text may be drawn shapes. MythosPDF recovers it first, then you make a scanned PDF searchable as usual.
How to do it
- 1.Drop your Microsoft Print to PDF file into MythosPDF. Drawn letters are turned back into text in a few seconds.
- 2.Add the scanned PDF.
- 3.Download the searchable PDF.
What people change in a research paper
- • Author names and affiliations
- • Typos in text and captions
- • Acknowledgements
- • Contact email
What that means when you make a scanned PDF searchable
- • Page tools work on the printout as it is; no text recovery is needed.
- • For a Microsoft Print to PDF file with drawn letters, opening it in the editor already recovers real text. OCR PDF instead adds an invisible layer and leaves the pages untouched.
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.
Questions people ask
+Does OCR change how the page looks?
No. The text layer is invisible.
+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.
