Converting the File into PDF/A

If you are the responsible student, you will receive an email from the UTUGradu system ( when your supervisor has initiated the examination process, and you are requested to fill in the information on the UTUGradu thesis form and submit the work to Turnitin originality check. Before this, however, the thesis file needs to be PDF/A converted and validated.

What is PDF/A? 

  • PDF/A is a document format for long-term storage and archiving. Its filename extension is .pdf. There are several types of PDF files, and not all files with a .pdf extension are PDF/A files.
  • To ensure that the file is a PDF/A file, the work is uploaded to the PDF/A validation tool before submitting the work to Turnitin.

The entire text of the thesis has to be in one file, including the title page, abstract, the appendices etc.
