Form File Upload in base64 format

Has anyone had any success converting a ‘file upload’ field in Webflow form to base64 format, and sending the data to Zapier? I have a file upload on my Webflow form for a user to upload an image, but I need the image to be sent to Zapier in base64 rather than Webflow hosted URL.
