Turnitin currently accepts the following file types for upload into an assignment:
- Microsoft Word™ (DOC and DOCX)
- Corel WordPerfect®
- Adobe PostScript®
- Plain text (TXT)
- Rich Text Format (RTF)
- Portable Document Format (PDF)
- Microsoft PowerPoint (PPT, PPTX, and PPS)
- Hangul (HWP)
For assignments that accept any file types the following image file types can be displayed and rendered in the Document Viewer:
All other file types that are not one of file formats listed above will be accepted by Turnitin when the assignment is set to "Accept Any File Type" but the file may not be displayed in the Document Viewer. When files cannot be displayed in the Document Viewer instructors are still able to download the original file from the Document Viewer.
The file size may not exceed 20MB. Files of larger size may be reduced in size by removal of non-text content or the instructor may be contacted to request multiple assignments to submit the document in sections.
Note: Text only files may not exceed 2 MB.
Note: PDF documents must contain text to be submitted. PDF files containing only images of text will be rejected during the upload attempt. To determine if a document contains actual text, copy and paste a section or all of the text into a plain-text editor such as Microsoft Notepad or Apple TextEdit. If no text is copied over, the selection is not actual text.
Tip: Users submitting scanned images of a document or an image saved as a PDF will need to use Optical Character Recognition (OCR) software to convert the image to a text document. Manual correction of the resulting document is highly recommended to fix any errors caused by the conversion software.
Note: Some document formats can contain multiple data types. This includes text, images, embedded information from another file, and formatting. Non-text information that is not saved directly within the document will not be included in a file upload. This includes references to a Microsoft Excel® spreadsheet included within a Microsoft Office Word document.
Note: Users whose files are saved in a file type that is not accepted by Turnitin will need to use a word processing program to save the file as one of the accepted types. Rich Text Format and Plain Text file types are nearly universally available in word processing software. Neither file type will support images or non-text data within the file. Plain text format does not support any formatting, and rich text format supports only limited formatting options.
Tip: When converting a file to a new file format, users should rename their file with a name other than that of the original file. This is suggested to prevent permanent loss of the original formatting or image content of a file due to it being overwritten.
