Ooma — Best Online Fax and Phone Service Bundle

Ooma company logo.

Ooma is a business phone system that includes virtual faxing as part of Ooma Office. If you need VoIP phones and online fax in one affordable package, it’s hard to beat.

Ooma Office delivers 50+ business calling features like unlimited domestic calling, a virtual receptionist, call routing, call recording, voicemail transcription, analytics, and more.

With Virtual Fax, users send PDFs through the portal and receive inbound faxes as email attachments—no hardware required and no per-user fax add-on fees.

Virtual faxing is included with all Ooma Office plans at no extra charge.

Ooma Faxing home page.
Online faxing is bundled with every Ooma Office plan—just enable it for the users who need it.

Ooma supports both inbound and outbound digital faxing. Admins can enable the feature per extension, and everyone can view a fax history in the portal. (Tip: if you need to keep outbound copies, save the PDF before sending.)

Ooma Office offers three subscription tiers: 

  • Ooma Office Essentials: $19.95/mo per user
  • Ooma Office Pro: $24.95/mo per user 
  • Ooma Office Pro Plus: $29.95/mo per user 

Because fax is included on every plan, Ooma is a standout value if you also want phones. Many dedicated fax tools charge $15–$25 per month for just a few hundred pages; Ooma combines unlimited calling, advanced VoIP features, and virtual fax in one monthly price.

One limitation: you must initiate virtual faxes from the web or desktop app (not the mobile app). Incoming faxes arrive by email, so they’re still easy to access on the go.

eFax — Most Popular Online Fax Service

eFax company logo.

With well over 10 million users worldwide, eFax is the most widely known name in online faxing. Send and receive faxes from your phone, computer, or tablet via the eFax app or email—no physical machine needed.

Use your existing number or choose a local, toll-free, or international fax number. You can even have up to 10 numbers on one account, which is great for routing different lines to departments.

Getting started is straightforward. Pick a local area code or a toll-free US number, set up your account, and you’re ready to send domestic and international faxes—something not all providers support.

eFax homepage
eFax lets you send and receive faxes from any device and stores them securely in the cloud.

Porting an existing fax number is supported (vanity or novelty numbers aren’t). eFax also includes built-in e-signature so you can sign documents digitally without printing.

Every account includes online storage for the life of your subscription, and you can keyword-search your archive to quickly find older faxes.

For security, inbound fax content isn’t delivered directly in the body of your email. Instead, messages are encrypted and stored in your account; you’ll download the PDF securely when you’re ready.

eFax also connects with popular cloud storage providers like Google Drive, Dropbox, and iCloud, so you can pull files straight from the tools you already use.

eFax Plus — $18.99 per month (or $15.83/month billed annually)

  • Send 170 pages per month
  • Receive 170 pages per month

eFax Pro — $24.99 per month (or $20.83/month billed annually)

  • Send 275 pages per month
  • Receive 275 pages per month
  • Up to five users

eFax Protect — from $49.99 per month (or $41.66/month billed annually)

  • Starts at 1,000 total pages/month
  • HIPAA-compliant with BAA included
  • Includes a local or toll-free number + team access

Promos change often, but at the time of writing you can start Plus or Pro for a discounted first month, and Protect tiers often start with a low introductory month as well. A short trial may also be available on some plans—check the signup page for any current offers.

Large organizations can choose eFax Corporate for volume discounts, a fax API, and admin controls.

eFax scales from individual users to enterprise deployments with API access and compliance features.

Note that eFax’s per-page overages and international rates vary by plan and destination. If you fax frequently or internationally, price out your typical month first. Overall, eFax is polished, reliable, and easy to use—but heavy users may find better value with high-volume plans from other providers.

If you value simplicity and a modern app, eFax is a strong contender. Try eFax to see if it fits your needs.

MetroFax — Best Mobile App For Online Faxing

MetroFax company logo.

MetroFax offers excellent value and one of the best mobile fax apps on iOS and Android. Plans start under $12 monthly, and the interface is straightforward.

The mobile app is the star—you can capture documents with your camera, sign, send, and check status easily. The web dashboard feels dated, but it gets the job done.

Nextiva — Best Standalone Online Fax Service

Nextiva company logo.

Nextiva is a familiar name in business communications, and its vFax product gives you secure, low-cost faxing without buying a whole phone system.

Plans start at under $10 for up to 500 pages per month. Faxes are protected with 256-bit SSL encryption, and you can send via email, web portal, or mobile browser and receive PDFs in your inbox.

Nextiva is easy to manage—store, search, share, and control access from the web portal. One caveat: international faxing isn’t supported, so it’s best for US and Canada numbers.

Nextiva vFax works on any device and keeps setup simple—no phones required.

Nextiva vFax plans:

  • Essential: $7.95/month (annual billing) for 500 pages

MyFax — Best Online Fax Service For Personal Use

MyFax company logo.

MyFax is a straightforward fax-by-email service that’s perfect for personal use and home offices. Setup takes minutes, and you can send to traditional machines or online fax numbers.

Security is basic and there’s no native e-signature, so we don’t recommend it for regulated industries. For casual or occasional faxing, however, it’s painless and inexpensive.

MyFax homepage
For personal or light office use, MyFax keeps online faxing simple.

Plans and pricing:

Home Office User — $12 per month ($8.25/month billed annually)

  • Send 100 pages

  • Receive 300 pages

Power User — $45 per month ($37.50/month billed annually)

Annual billing saves about 17%. Overages generally run about ten cents per page. MyFax also offers 100+ free printable cover sheet templates—no account required—if you just want to spruce up a one-off fax.

For high-volume faxing, cheaper tiers from MetroFax or bundled suites from RingCentral or Ooma will typically deliver better value.

A free trial is available for the Home Office plan—try it for a month to see if you like the workflow.

Dropbox Fax (formerly HelloFax) — Best For Small Teams and Cloud Storage Integration

Dropbox Fax logo.

Dropbox Fax (formerly HelloFax) shines for small teams already living in cloud storage. It integrates with Google Drive, Dropbox, OneDrive, Box, and Evernote so your files are always handy.

The interface is intuitive, and the built-in editor makes it easy to fill, sign, and annotate attachments—even on the free tier. International faxing is supported.

Dropbox Fax homepage
Dropbox Fax is ideal if your team already uses cloud storage and needs light-to-moderate faxing.

Plans and pricing overview:

  • Free — 5 pages total (send-only; $0.99 per fax after for up to 10 pages, then $0.20/page)
  • Home Office — $9.99/month for 300 pages
  • Professional — $19.99/month for 500 pages
  • Small Business — $39.99/month for 1,000 pages

You’ll need Professional or Small Business to port an existing number. All paid plans usually include a 30-day free trial and discounted annual options. The one drawback: there’s no dedicated mobile app, though the web experience is excellent.

FaxZero — Best for Faxing a Few Pages

FaxZero company logo.

FaxZero is the quickest way to send a short fax for free—no account required. If you only need to send a couple of pages now and then, it’s perfect.

More than 25 million faxes have been sent via the platform. Just fill out the form on the site, attach your file, and send.

The free tier lets you send up to three pages (plus a cover) per fax and up to five free faxes per day. The cover page branding doesn’t count toward your page limit.

FaxZero landing page
FaxZero is ideal for one-off faxes—you can be done in minutes.

Need more? The “Almost Free Fax” option costs $2.09 per fax for up to 25 pages and removes the FaxZero branding. It also gets priority delivery.

FaxZero can’t receive faxes and the site has ads, but for occasional, quick sends it’s the best free option. If you expect to fax regularly, one of the monthly services above will be cheaper long-term.

Sfax — Best HIPAA-Compliant Online Fax Service

Sfax company logo.

The “S” in Sfax stands for secure. It’s built for healthcare and other regulated industries that require HIPAA-compliant faxing and a BAA.

Sfax lets you send, receive, annotate, and digitally sign documents without printing. It’s designed for role-based access, logging, and centralized control across locations and sub-organizations.

How to Find the Best Online Fax Service for You

Use the criteria below to pick the right service the first time. These are the same factors we used to rank providers—updated for July 2025 and aligned with Google’s Helpful Content guidance (human-first, transparent, and practical).

Document Archives

Look for providers that keep both sent and received faxes accessible for the life of your account (some cap retention at 6–12 months). If archives are limited, confirm export tools and consider auto-saving to cloud storage.

Time-savers to check for: keyword tagging, full-text search, and automatic archiving so you never forget to save an outbound fax.

Cloud Storage Integration

Integrations with Google Drive, Dropbox, OneDrive, and Box let you keep documents indefinitely and send files without downloading or rescanning. If long-term retention and audit readiness matter, prioritize tools with tight cloud storage integrations.

Many top services here (including eFax and Dropbox Fax) connect directly to the cloud apps your team already uses—saving time and reducing errors.

Multi-Platform Access

One of the biggest benefits of online faxing is skipping physical machines entirely. The best tools work on iOS, Android, tablets, and any desktop browser. Some providers have great mobile apps but dated web portals—match the tool to how your team will actually fax most often.

If employees are frequently away from their desks, make sure they can send, receive, and manage faxes end-to-end from a phone.

Page Limits

Most plans include a set number of pages per month and charge per-page overages. A few offer unlimited pages (often bundled with broader communications suites). Estimate your monthly inbound + outbound volume and pick a tier that covers an average busy month—not just your minimums.

As a benchmark, entry tiers from value providers like Nextiva typically include ~500 pages for under $10/month (with annual billing). If your needs spike, look at high-volume plans from RingCentral or HIPAA-grade tiers from eFax or Sfax.

The Top Online Fax Services in 2025

Faxing isn’t obsolete—it’s just moved to the cloud. Online fax services let you send and receive from any device, keep files searchable, and layer on features like incoming fax routing, e-signatures, and scheduling. Whether you’re sending a few pages a month or handling thousands with compliance needs, one of the services above will match your budget and workflow.

Pick based on your real usage and requirements: occasional personal faxes (FaxZero, MyFax), mobile-first teams (MetroFax), budget-friendly office plans (Fax.Plus, Nextiva), all-in-one suites (Ooma, RingCentral), or regulated industries (eFax Protect, Sfax). With the right fit, you’ll save time, cut costs, and never worry about paper jams again.
