mFax

mFax is an online faxing service that lets users send and receive faxes through a web browser or mobile app on iPhone, Android, Windows, or any device. The platform accepts various file types—documents, spreadsheets, photos, and slides—and automatically converts them into fax-ready pages. Users can add cover sheets, customize sender information, and track delivery confirmation.

The service is free to start with a 7-day trial period. It includes features like document scanning via camera, automatic edge detection and cropping, and incoming fax management. The maker built it with Lovable.
