Google Forms file upload limits calculator

Planning a form that collects files? Enter how many people will respond and how big their files are. The calculator picks the Google Forms settings you need (max file size, number of files, form total) and warns you before you run out of Drive space or hit the form's cap mid-collection.


Free Google accounts include up to 15 GB shared across Gmail, Drive and Photos (Google).

FAQ

What is the maximum file size for a Google Forms file upload?

Per question you pick a maximum of 1 MB, 10 MB, 100 MB, 1 GB or 10 GB per file (as documented by freeCodeCamp and groovyPost; Google's own help page lists the setting without the values).

How many files can a respondent upload to one question?

1, 5 or 10 files per question (freeCodeCamp). For more, add another File upload question.

Is there a total limit for the whole form?

Yes. A form accepts up to 1 GB of files by default, and you can raise it to 10 GB, 100 GB or 1 TB. When the limit is reached the form stops accepting responses (groovyPost).

Whose storage do uploads use?

The form owner's. Uploaded files are stored in a new folder in the owner's Google Drive (Google), and each Google Account includes up to 15 GB shared across Gmail, Drive and Photos (Google One Help). If you're over quota, you can't upload new files to Drive.

Do respondents need a Google account to upload?

Yes. Google: “To answer this question, responders need to sign in to a Google Account” (Google Help). There's no setting to turn it off.
