JUST THE FAX
Send your friends a fax. It will not be a good one.
It ruins your photos properly
Not a filter. A real 1-bit fax — dithered to pure black and white, squashed to genuine fax proportions, with a header line across the top and a streak down it from a dirty roller. Your friend's face has never looked worse.
Nothing leaves your device
No account, no sign-in, no server, no tracking. The fax is made on your phone and goes nowhere until you hand it to someone yourself. There is nothing here to collect.
Nothing to install
It runs in a browser, so anyone you fax can reply from the link on the page without downloading anything. Put it on your home screen if you like it.
