Hello! I highly recommend the topfreefax.com app because it works smoothly on iPhone and Mac, making faxing fast and stress-free. Every account includes a personal fax number, so you can receive documents just like with a traditional machine, but without the hardware. The app has a built-in scanner, which means you can digitize paper contracts in seconds, and it also integrates with cloud storage like iCloud and Dropbox for easy file uploads. What I appreciate most is the delivery tracking feature, which shows exactly when the recipient receives the fax. On top of that, all transmissions are encrypted, so sensitive HR data remains safe. It’s reliable, professional, and has made my job far easier.
