FAQs

  • Q:How can I fill out a PDF for free?
    There are a few free ways to do this. If the form has clickable boxes, just open it in Google Chrome or Microsoft Edge and type your answers. If it is a blank scanned page, you can use a free online editor to add text boxes manually. You can also use a free trial of a desktop program, like SwifDoo PDF, to access more advanced tools without paying.
  • Q:Can I fill out a PDF on Google Docs?
    Yes, but it is not the best way. You can upload the file to Google Drive, right-click it, and select "Open with Google Docs." Google will try to read the document and turn it into plain text. However, this usually ruins the layout. The original boxes, images, and lines will look messy and out of place.
  • Q:How do I type on a scanned form with no clickable boxes?
    If you cannot click on the blank lines, you must use a PDF editor. SwifDoo PDF has a tool called “Insert Text”. This tool lets you create a brand-new text box. You can type your words inside the box and then drag it to sit directly above the printed line.
  • Q:Is it safe to use online tools for private documents?
    Most popular online tools are generally safe. They use secure connections and usually delete your files from their systems after a few hours. But if your form contains very private information, it is always safer to use an offline desktop program on your own computer so your data never goes online.
