Is it possible to restrict the file type and size that customers can upload?

Yes, you can set both the file type and file size limitations from the Uploader Settings. When configuring a file upload field, simply specify the allowed file types (such as JPG, PNG, PDF) and define the maximum file size (in MB). These settings ensure customers can only upload acceptable files and prevent oversized or unsupported files from being submitted.

You can also define how many files a customer is allowed to upload through a single field, offering full control over the file submission process during checkout.
