How to upload files to Google Forms without a sign in?

You can add a file upload question in your Google Form to allow your users to upload file(s) as response to the question, but this option requires sign in. You can use the Formfacade add-on to convert Google Forms' file upload question into HTML file upload and let your users upload files without sign in.

What is the difference between Google Form's file upload and Formfacade's 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 Drive 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.
