Faxvio

Faxvio is a pay-as-you-go online fax service for sending faxes from a web browser, iPhone, iPad or Mac. There's no subscription, no fax machine and nothing to install on the web. Upload a PDF or a photo, enter the fax number, and Faxvio shows a black and white preview of how each page will print on the receiving machine, plus the exact price, before you pay. Your first page is free. After that you buy page packs starting at $1.09, as low as $0.18 per page, and pages never expire. If a fax fails, the pages go back to your balance automatically. Faxvio marks a fax as Delivered only after the receiving machine confirms it, and every fax gets a PDF receipt with the date, time, number and transmission ID. Faxvio sends faxes to 37 countries, including the US, Canada, the UK, Germany, France, Japan and Australia. It also has free fax tools: a cover sheet generator, number formatter, quality preview and cost calculator.
