You can easily add documents stored on your computer to your Interfolio account. You'll need to create a placeholder for the document, which you can do from your accounts  "Home"  page or your  "Documents " page.

In your accounts "Home"  page please go to Dashboard and click on  "Upload a Document".   You can also go to your accounts "Documents" page and got to "Add Document".

From  "Upload a Document " or "Add Document"  click on the drop down arrow to select a document type, then give a unique title to your document and choose how to get the document into your account.

Please note you will not be able to upload a document if you select these document types: Confidential Letter of Recommendation, Confidential Evaluation, Non Confidential Recommendation letter, and Transcript.

Since the document is already on your computer, choose the option that reads “Electronic document - You have an electronic file that you are able to upload now.” Find the document on your computer, and then upload it. The document may take a few minutes to convert, so don't worry of the status is “Converting” for several minutes.
