How to Write on a PDF document — Adobe To mark up a page, you'll need to use an online editor and open your PDF into that editor. If you're on a Mac or PC, using our PDF to HTML converter will do an excellent job of formatting your PDF. Once a page has been turned into HTML, it can be sent as an email attachment to any website you choose, or uploaded to a form. We've found that writing on a PDF document is easy, but it is important to pay attention to the formatting of your document, because it can affect your ability to format other documents in other ways. Note and warning: If you are trying to send an email attachment that does not contain writing on the page, be sure to click the “Confirm” button to attach correctly. If you do so, you shouldn't get an error about a bad page. If you are sending a PDF file in a zip file, it is important to make sure that the file format matches the formatting used on the website you're sending to. If the text inside the page is white text on a black background, the file should be saved to Adobe PDF format. Other formats (e.g. Adobe XPS or .eps) have issues when using the “Confirm” button.
