Choosing Based on Your Faxing Patterns
Occasional Faxers (1–3 times/month): Use pay-as-you-go (Dropbox Fax at $0.99/fax) or free options (FaxZero for US domestic; Fax.Plus for 10 pages/month permanently). Avoid monthly subscriptions unless you exceed 15–20 pages.

FAQ
What do people use now instead of fax machines?
Modern businesses use cloud-based internet fax services like Municorn Fax App, Dropbox Fax, and eFax to eliminate physical machines. Email, secure file sharing (Google Drive, Dropbox), and e-signature platforms also replace faxing in many workflows. However, regulated industries (healthcare, law, finance) still require fax for compliance, making digital fax services the standard replacement in 2026.
Can you fax with just internet?
Yes. Internet fax services allow you to send and receive faxes using only a computer, smartphone, or tablet with an internet connection. No fax machine or phone line is required. Upload documents, enter a fax number, and send via web portal or mobile app. Incoming faxes arrive as PDF email attachments or in-app notifications.
What is the best free internet fax software?
FaxZero offers the simplest no-signup-required free sending (5 faxes/day, 3 pages each, to US/Canada). Fax.Plus provides a permanent 10 pages/month free tier. For unlimited features, Municorn Fax App ($9.99/week) delivers the highest value when faxing regularly. Choose based on frequency: one-off = FaxZero; regular = Municipron or Fax.Plus free tier.
Is Google fax free?
Google does not offer a native fax service. However, Google Drive users can access faxing through Dropbox Fax, which integrates with Google Drive for document storage and retrieval. Dropbox Fax itself is not free (starts at $9.99/month), though it includes 5 free pages initially.
What is the most secure online fax service?
Services with SOC 2 Type II, ISO 27001, and HIPAA certifications rank highest for security: eFax (HIPAA, HITRUST, SOC 2 Type II), SRFax (HIPAA, BAA), and Municorn Fax App (ISO 27001, Compliancy Group verified, HIPAA with BAA). All use AES-256 encryption at rest and TLS in transit. For maximum security, verify the provider’s published trust certifications and BAA availability before signing.
Which internet fax service is best for small businesses?
Municorn Fax App ($9.99/week unlimited) or Dropbox Fax ($9.99/month for 300 pages) suit most small businesses. Municorn Fax App excels for teams needing unlimited faxing without page monitoring. Dropbox Fax is ideal for businesses already using Dropbox or Google Drive. For compliance-required sectors (law, healthcare), SRFax ($12.60/month) or eFax ($13.43/month) include HIPAA at no extra cost.
