To submit a paper to Turnitin, your paper must meet the submission requirements. If an assignment is set to "Allow Any File Type," Turnitin will accept any file that is less than 20 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 Originality Reports will be allowed to be submitted to the assignment.
The paper being submitted must contain more than 20 words, must be under 20MB , must not exceed 400 pages in length, and must not contain spaces in between every letter (l i k e t h i s).
Therefore, if an unsupported word processor is being used, you may need to save the file as a TXT or RTF file in order to upload to Turnitin.
highly recommend that users pay attention to the image preview provided in the single file submission after clicking on "Upload" button to verify that the file is presented in an acceptable manner.
If a file format issue is occurring, 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"). Occasionally content in document headers and footers can prevent a file from being accepted by the Turnitin service. If you encounter issues uploading a document that contains headers and footers, editing or removing the content may resolve the issue
