Best online fax services

Fax.Plus stands out with modern design, a strong mobile app, and the lowest month-to-month paid entry price in our current lineup. Basic costs $8.99/month, or $6.99/month when billed annually, for light non-HIPAA faxing. HIPAA and a BAA require Enterprise at $99.99/month, or $79.99/month billed annually, and e-signatures run through Sign.Plus integration.

RingCentral Fax offers the best pages-per-dollar ratio in our current lineup, with 3000 pages on its standalone Fax 3000 plan plus HIPAA compliance and API access. It is strongest for business and healthcare teams that can evaluate per-user pricing.

SRFax is the healthcare specialist of our lineup: the plans shown here are its HIPAA-ready healthcare tiers with a BAA on request, verified on SRFax's own plan builder. It also sells standard small-business plans that its materials list from $9.95/month; we publish the healthcare lineup we could fully verify. Accounts are available in the U.S. and Canada.

Nextiva vFAX is a budget-oriented business fax service from an established VoIP brand. Essential costs $9.95/month month-to-month, or $7.95/month billed annually, for 500 pages — one of the largest entry-tier allowances in our lineup. HIPAA compliance is offered through a separate dedicated plan, and faxing runs through the web portal or email.

eFax is one of the oldest online fax services, offering wide number availability and solid reliability. Best suited for users who value brand recognition and broad international coverage, though newer competitors offer better value per page.

Dropbox Fax is a strong choice for teams already using Dropbox-style document workflows and signature fields before send. It is less attractive for affiliate monetization versus RingCentral, eFax, MyFax, or Fax.Plus programs.

iFax is an app-centric fax service with a steep feature ladder: the entry Basic plan only sends, while receiving, a fax number, HIPAA compliance, and the well-rated mobile apps arrive on Plus and Pro. Month-to-month rates are $14.99/$29.99/$39.99 per iFax's own pricing cards; annual billing lowers them to $12.49/$24.99/$33.33. The web signup path offers a 3-day free trial of Pro.

MyFax is a straightforward option for users who just need basic faxing without bells and whistles. Its page-per-dollar ratio is not the best, but the simple interface and number porting may appeal to users transitioning from a physical fax machine.
