Can I add a file upload option in my forms?

Yes, you can use a file upload question in your form to allow your users to upload a file as response to the question.

What's the difference between Google file upload and Formfacade HTML file upload?
Google Form's file upload question requires your users to be signed in to a Google account to upload their file and submit their response. The files are uploaded to the form creator's Google Drive.

Formfacade converts the Google file upload into a HTML file upload. The users will be able to upload a file using the upload file button and submit the form without having to sign in with a Google account. In the Google form, the file upload question will be converted in to a short answer question, where the url location of file uploaded by the user will be displayed.
