Free Fax Online: Common Questions & Answers

Can I fax with Gmail?

Yes. Services like Fax.Plus, CocoFax, and Dropbox Fax support email-to-fax: forward a document to a fax address, and it transmits to the recipient's fax machine. Gmail itself doesn't fax natively, but these integrations route through Gmail's infrastructure to send.

Can I fax from Google for free?

Partially. Fax.Plus integrates with Google Docs, allowing you to fax directly from Google Docs without leaving the app. Dropbox Fax works with Google Drive files. Both offer free page allowances, though limits apply. Standard Google services (Gmail, Drive alone) do not include native fax capability.

Is eFax still free?

eFax offers a free 7-day trial with 170 pages and full send/receive capability. After 7 days, a paid subscription is required. There is no permanent free tier; the trial is the only free option. If you need ongoing free faxing, choose FaxZero, Fax.Plus, or CocoFax instead.

Can I receive faxes online free?

Rarely. CocoFax allows receiving inbound faxes on the free tier (10 pages one-time). eFax trial supports receiving during the 7-day period. Most services require paid plans for inbound capability. For receiving, expect to pay $10–$25/month for a dedicated fax number and inbound allowance.

FaxZero is the longest-running: 15 pages/day (5 faxes × 3 pages) to US/Canada, no signup, no account needed. GotFreeFax is the alternative: 6 pages/day (2 faxes × 3 pages), also no account. Both are instant and truly free; choose FaxZero for higher daily limits.
