Customer Facing Infomation

Please review the guide below to help resolve issues preventing you from uploading papers to

If you have a firewall and/or anti-virus (e.g., AVG) installed on your computer, then it may prevent Turnitin from working correctly. Note that sometimes, just using a different browser will resolve upload issues. For example, if you are using Internet Explorer, try using Mozilla Firefox or Google Chrome.

To submit a paper to Turnitin, your paper must meet our requirements. If an assignment is set to "Allow Any File Type," Turnitin will accept any file that is less than 40 MB AND less than 400 pages in length. If the assignment is set to "Allow only file types that Turnitin can check for originality," only files that can generate Similarity Reports will be allowed to be submitted to the assignment.

Turnitin will currently accept the following file types to generate Similarity Reports:

  • Microsoft Word® (.doc / .docx)1
  • OpenOffice Text (.odt)2
  • Google Docs via Google Drive™ (.gdoc files are NOT acceptable)3
  • WordPerfect®  (.wpd)
  • PostScript (.ps/.eps)
  • Adobe® PDF4
  • Microsoft PowerPoint® (.pptx, .ppt, .ppsx, and .pps)5
  • Microsoft Excel® (.xls and .xlsx)6
  • HTML 
  • Rich text format (.rtf)
  • Plain text (.txt)
  • Hangul Word Processor file (.hwp)

Your paper must contain a minimum of 25 words, must be under 40MB (or approximately two million characters), less than 400 pages in length, and must not contain spaces in between every letter (l i k e  t h i s).

Please note that we do not support:

  • Microsoft® Works (.wps) file types.
  • Apple Pages file types.
  • Spreadsheets created outside of Microsoft Excel (i.e. .ods).
  • GDOC*** files (.gdoc) which are just links to online Google Document files, but don't actually contain text or the document's content. Google Drive must be used to upload Google Docs.

Therefore, if you are using an unsupported word processor, you may need to save the file as a .txt or .rtf file in order to upload to Turnitin.

If submitting with Google Drive™ online storage service, third party cookies must be allowed in your browser, or attempts to sign into Google to upload from Google Drive will fail. Note that Google Drive functionality is not supported with IE8 or below.

1Note - Microsoft Word: We do not accept Microsoft Word 2007 macros-enabled (.docm) files (we do accept the standard .docx files). Whatever macro is encoded in the file is stripped away when submitted to Turnitin. For example, when using a "letter replacement macro," we strip the macro from the Wordfile, and whatever characters the student originally had in the file will appear (i.e. "a~"). Also, we do NOT accept password protected files.

2Note - Open Office Text: Turnitin will not accept .odt files created and downloaded from Google Docs online. Turnitin will not accept ".doc" files created using OpenOffice since OpenOffice ".doc" files are not 100% Microsoft Word equivalent.

3Note - Google Docs: GDOC files (*.gdoc) which are just links to online Google Document files, but don't actually contain text or the document's content are not supported. Google Drive must be used to upload Google Docs.

4Note - Adobe® PDF: Turnitin will not accept PDF image files, forms, or portfolios. PDF files which do not contain highlightable text (e.g., a "scanned" file, which is often simply a picture of text) are unacceptable. PDF portfolio documents containing multiple files are not supported.

5Note - Microsoft PowerPoint: It is possible to submit PowerPoint files through,, Turnitin Basic integrations, newer versions of the Turnitin Direct integrations, and LTI compliant integrations only. It not possible to submit PowerPoint files using other non-LTI compliant integrations. 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 3-D be removed prior to submitting to Turnitin.

6Note - Microsoft Excel: 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. 

Files uploaded to Turnitin must have correctly matching file extensions.  For example, if you save a document as a Word file, it must have a Word extension (.doc or .docx).  Turnitin will automatically reject files with mis-matched extensions (e.g., a .doc Word file manually edited to a .rtf extension without using the "Save As" feature).  If you are experiencing a file format issue, please re-open the file in a word processor, and save the file again using the "save as" function and choosing a different format from the file type pull down menu (try .rtf or .txt as they are the most "safe").

As mentioned above, if you have a firewall enabled (such as those included with many Antivirus programs like McAfee, Norton, and AVG) it may prevent you from uploading a paper to Turnitin successfully.  If this is the case, please add the following as a “safe site” (i.e, Trusted Site or WhiteList) to your firewall and/or browser:


If you do not know how to do this, please contact the help desk for the antivirus/firewall program in question for instructions.  Also, you must use a supported internet browser in order to successfully submit a paper.  Please update your internet browser to the latest supported version if you have any doubts about this.

If you continue to experience upload issues, you may try "disabling" all your browser's plugins/extensions and try uploading again. You can re-enable the plugins/extensions after your upload attempt.  If issues persist, please provide your file to Turnitin Support so that we can take a look at the paper from our end.  Also, please let us know the word processor and version you are using to write your paper.

As an alternative, please submit your paper by cut and paste:
  1. Select "cut and paste" using the pull-down on the paper submission page.   
  2. Open your paper in a word processing program and highlight the paper's text either by using your mouse or by choosing "select all" in your program's edit menu.   
  3. To copy the text of your paper, select "copy" from the edit menu.   
  4. Place your mouse cursor in the text box of your browser. To paste the text into your browser, select "paste" from your browser's edit menu.   
  5. Verify that all of your paper's text shows up in your browser. To submit your paper, click the "submit" button.
