If what you need is to add extra text, such as a job description or a signature to your resume, go to get the SwifDoo PDF for iOS or Android app from the App Store or Google Play. You can edit your resume on your smartphone using online PDF file editors like Sejda or Canva or a mobile app like CV Maker Resume PDF Editor. The former is accessible in a browser without downloading it. You can also subscribe to the Adobe Acrobat mobile app to do the editing.
