Yes. Pages with a text layer become editable Word paragraphs that keep their font sizes, bold and italic, colors, images, tables and some column layouts. For scanned pages, run OCR in Starix PDF first. After exporting, check complex tables, vertical text and page breaks in Word.
Excel puts each recognized table on its own worksheet, with the values shown in the PDF, and exports the other pages as rows of text. PowerPoint makes one slide per page, with searchable text boxes placed over the page image. To change the wording on a slide, edit the PDF first, then export.
A signature or seal placed with Sign & Seal becomes part of the page when you save, applied redaction permanently removes the marked content, and flattening turns the affected pages into images. Keep the original file and review the copy before you send it. To add a certificate digital signature, use your own certificate.
