Summary
A file upload question lets responders attach documents, images or PDFs directly to their form answers. You control which file types are accepted and how large each file can be, so submissions arrive in a format you can use.

Open your form and click the question you want to change. Type your question text, then click the Multiple choice drop-down at the right of the question card to see the list of question types.
Step 2
Choose File upload
In the list, click File upload. The list includes options such as Short answer, Paragraph, Checkboxes and Dropdown, so look for File upload below Dropdown.

Confirm the file upload prompt
A prompt appears with Cancel and Continue buttons. Click Continue to switch the question to a file upload.
Step 4
Limit the file types

Step 5
Allow PDF files
Under the file types, tick the formats you accept. The list includes Document, Presentation, Spreadsheet, Drawing, PDF, Image, Video and Audio. Tick PDF to accept PDF files.
Step 6
Set the maximum file size

Why this matters
You are collecting signed consent forms, résumés or event paperwork and do not want to chase attachments over email. A file upload question puts every submission in one place and keeps out file types you cannot open.
