If you have advanced, professional faxing needs—like sending HIPAA-compliant faxes or customizing a fax cover page with a logo—SRFax is the best online fax service we tested for frequent business use.
Best free or inexpensive faxing for occasional use
With HelloFax, you can send high-quality faxes for free or for a low flat rate. There’s no monthly subscription required, unless you also want to receive faxes.
If you need to send a fax only once in a blue moon—to request a copy of your medical records, for example, or to send a signed loan agreement to a bank that requires faxes—we think you should use HelloFax. The service starts you out with five free outbound pages, and you can earn additional free pages for doing things like tweeting about HelloFax or inviting someone to sign up. After that, it’s just 99¢ to fax up to 10 pages and then 20¢ per additional page. In our tests, HelloFax sent clear, easy-to-read faxes, and it reliably received all the test faxes we sent to our account, when we paid for the receiving option. Its simple, easy-to-use interface makes the occasional chore of sending a fax quick and painless, too.
Secure, business-friendly faxing for monthly use
SRFax meets high-security legal requirements, such as HIPAA, and offers robust features at low subscription rates.
If you need to digitally send and receive faxes on a regular basis, we’d recommend subscribing to SRFax. In addition to its competitive pricing and solid fax quality, SRFax offers HIPAA compliance for health care organizations, as well as advanced security and privacy features, like spam-fax blocking and the option to specify how long you want the service to store your sent and received faxes. SRFax can’t send a fax from your cloud-storage app, but otherwise it provides excellent value for a home office or small business, whether you send and receive 25 pages a month or 2,500.
