What types of files does Turnitin accept/read?

File Types:

For Turnitin to produce an originality report, a minimum of 20 words in a text-readable font must be included.

If any file type has been allowed, then there is no minimum number of words required, however, an originality report may not necessarily be generated.

If you are required to submit an assignment which is going to produce an originality report, your submitted document must comply with the following requirements.

Turnitin currently accepts the following file types for upload into an assignment:

     Microsoft Word™ (DOC and DOCX)
     Open office text document (.odt)
     Corel WordPerfect®
     Adobe PostScript®
     Plain text (TXT)
     Rich Text Format (RTF)
     Portable Document Format (PDF)

For more detailed information about acceptable file types please see this page:


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.

Please note : Documents created using Pages for Mac ( Redesigned for OS X Yosemite) are not accepted. Please convert the document into one of these formats: Microsoft Word (.Doc, or .Docx), Rich Text (.RTF), or plain text (.txt) formats.

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.

Please also note, in particular for Apple Macintosh PC users: When you upload your paper to Turnitin, an originality report is generated. If you upload your paper and a report is not generated, even though the paper appears to have been accepted, and it appears to be in an accepted file type such as Microsoft Word .doc or .docx format from your Mac, or pdf format, it means your submission has not been accepted. It may be that you have saved the document in a template .docx file format, which is not accepted.

File Size:

The file size must not exceed 40MB, nor must the document contain more than 400 pages. 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.

To check the file size before attempting to upload your paper, locate the document in your filing system, right click on it, and select Properties.  The number next to where it says "Size:" is the file size that needs to be under 40MB.

Managing Images You Insert Into Your Document So Your Document File Size Remains Within The File Size Limit:

Method 1:

If your essay or dissertation paper is going to contain embedded images or graphics, you must take care to prepare these images before you import them into your document. You can easily do this with freely provided image editing software which is installed on your computer, such as Microsoft Paint. If, for example you have a 4MB image that you want to use, prior to inserting the image into your Word document, first open it in Microsoft Paint, re-size it 800 pixels wide - you may want to experiment with sizes - and save this as a new image. The file size of this new image will be a tiny fraction of the original, such as 100KB, which is 1/40th of the original size, with barely a perceptible loss of quality or resolution. Experiment and choose image sizes that balance quality with file size such that, when they are loaded into your Word document, the Word document size does not grow too large and exceed the 40MB file size limit.

Method 2:

If you have not prepared your graphics before inserting them into your document, a quick solution to try is to click on an image in your document, then click on the Format Picture Tools on the top menu. In the first set of tools that appear, there is a Compress Pictures tool. A dialogue box opens, asking whether to compress the selected picture, with the check-box selected, or uncheck the check-box to compress all the images in the document. Then click OK. Then save as a new version of your document, and check the file size.
