Big File Form Uploads brings large, chunked uploads to Gravity Forms File Upload fields. Once the add-on is active, your File Upload fields inherit the maximum upload size from Big File Uploads and send files to your server in small pieces — so your visitors can submit large files without hitting host limits or timeouts.

This guide shows you how to add a large-file upload field to a Gravity Forms form.

## Before You Start

Make sure the following are active:

- Big File Uploads (free parent plugin), with your maximum upload size set under Settings → Big File Uploads → Uploading Files.

- Big File Form Uploads (the add-on).

- Gravity Forms.

## Step 1: Add a File Upload Field

- Go to Forms and open (or create) the form you want to edit.

- From the field panel, add a File Upload field under Advanced Fields.

- Drop it into your form layout.

## Step 2: Save the Form

This step matters. When you save the form, Big File Form Uploads prepares your File Upload fields for chunked uploading — it enables multi-file mode so the chunked uploader can take over.

- Click Update (or Save Form) after adding or editing a File Upload field.

- If you ever change your maximum upload size in Big File Uploads, no form changes are required — the new limit is applied to the uploader automatically.

## Step 3: Test the Upload

- Preview the form or visit the page where it's embedded.

- Choose a large file in the File Upload field.

- Submit the form.

The file is uploaded in small chunks before submission. The form won't complete until the upload finishes, so you never receive a partial entry.

## Good to Know

- Field upload limits. Big File Form Uploads sets the uploader's maximum size from your Big File Uploads setting. If you've set a smaller "Maximum File Size" on the field itself in Gravity Forms, that lower value still applies — raise it if you want visitors to use the full limit.

- Multi-file fields. When the add-on prepares a single File Upload field for chunking, it switches the field to multi-file mode. If you need visitors to attach more than one file, increase the Maximum Number of Files on the field.

- The limit is global. The maximum size comes from Big File Uploads and applies across all your Gravity Forms File Upload fields.
