File Upload Forms for Google Drive
Forms Studio is a nocode online forms builder for creating file upload forms that resemble Google Forms. See sample form.
You can include one or more file upload buttons in your web forms and receive files from anyone. The uploaded files are saved directly in your Google Drive, neatly organized in folders while the form response is saved in Google Sheets.
Your forms can have CAPTCHAs to prevent spam, you can protect forms with passwords and also include multiple e-signatures to let people sign the form before submission.
Forms Studio is powered by Google Scripts and the files are uploaded to Google Drive with the Google File Picker. You (form creator) need a Gmail or GSuite account but the form submitter doesn't need a Google Account. Your form can even allow anonymous file uploads and form submissions.
