File type Note
  • Microsoft Word® (.doc/.docx)
  • OpenOffice Text (.odt)
  • WordPerfect® (.wpd)
  • PostScript (.ps)
  • HTML
  • Hangul Word Processor file (.hwp)
  • Rich text format (.rtf)

Turnitin® will not accept PDF image files, forms, or portfolios, files that do not contain highlightable text (e.g. a scanned file - usually an image), documents containing multiple files or files created with software other than Adobe Acrobat®. (Source: Turnitin)
  • Microsoft PowerPoint® (.pptx, .ppt, .ppsx, and .pps)
It is possible to submit PowerPoint® files through,, Turnitin Basic integrations, newer versions of the Turnitin Direct integrations, and LTI compliant integrations only. Turnitin converts the PowerPoint® slide deck into a static PDF, leaving all text and images in their original format but leaving out features such as presenter notes, embedded video, and animations. Text with visual effects is not supported, and it is recommended that any visual effects such as shadows and 3D be removed prior to submitting to Turnitin. (Source: Turnitin)
  • Microsoft Excel® (.xls and .xlsx)
The version of the file that can be viewed in the Document Viewer will look the same as it would if the Excel file had been saved as a PDF and submitted to Turnitin. We highly recommend that users pay attention to the image preview provided in the single file submission to verify that the file is presented in an acceptable manner. Users can adjust the way the file looks by editing the page setup and print area settings for the file prior to saving it and submitting it to Turnitin. (Source: Turnitin)
