File upload
Let respondents attach files to a public Google Form without ever seeing a "sign in with Google" prompt. The File Upload addon replaces a Short Answer or Long Answer field with a branded upload UI, and CustomGForm stores the file for you.
Works on Short Answer and Long Answer fields only. Add it from Field addons in the form customizer.
Key capabilities
- Restrict uploads to specific file types or whole groups (images, documents, archives, ...)
- Cap the number of files and the max size per file
- Custom upload label and description shown to respondents
- Uploaded file links appear alongside the response in the Results tab
Plan availability
File upload is a paid feature: it is not available on the Hobby plan. Starter allows up to 10 files per submission at 10 MB each (2 GB total storage); Pro raises that to 100 MB per file and 20 GB of storage.
