If you're using Google Forms to collect offer details, client intake info, or anything that requires documents—like pre-approval letters, proof of funds, or signed disclosures—Google’s File Upload feature is a game changer.

It allows respondents to easily attach documents directly to your form submission, saving you from chasing down missing files later. But there are a few important things to know before you start using it.

How to Add a File Upload Question

Here’s how to allow file uploads in your Google Form:

Click the + Add question button in your form.
Change the question type to File upload.
Google will prompt you to allow uploads—click Continue.
Customize your question (e.g., “Please upload your buyer’s pre-approval letter (PDF preferred).”)
Set limits:
- Choose accepted file types
- Choose how many files respondents can upload
- Set a maximum file size (up to 1 GB)

Once your form is active, uploaded files will be stored in your Google Drive, and links to each file will appear in the linked Google Sheet. Everything stays in one place and neatly organized.

Restrictions to Keep in Mind

Before you start collecting documents, here are a few things you (and your respondents) need to be aware of:

1. Respondents Must Be Signed into a Google Account

File uploads only work for users who are signed in with a Google account. If someone tries to submit the form without being signed in, they’ll be prompted to log in first.

💡 Tip: Add a note in your form description to let users know they’ll need to sign in with Google.

2. Storage Limits Apply

Uploaded files are saved in your Google Drive, and they count against your storage limit. If your Drive is full (or close to it), uploads may fail. Make sure you have space, especially if you expect a lot of submissions or large files.

3. Privacy is Built In

Uploaded files are only visible to you, the form owner. Other respondents can’t see each other’s documents.

When Should You Use File Uploads?

This feature is great when you want to keep everything in one place. Some common uses for real estate professionals include:

Pre-approval letters with an offer submission
Signed seller disclosures or repair receipts
Proof of funds
ID verification for transaction coordinators

Instead of managing everything through email (and risking missed attachments), using file uploads in your form creates a smoother, more professional experience for everyone involved.
