Online Fax Services Reviews
1. Fax.Plus — Most Cost-Effective Faxing Service
Fax.Plus is a low-cost service for faxing a document online.
They have a simple free plan and four paid plans (Basic, Premium, Business and Enterprise), billed monthly or annually. Current prices are on Fax.Plus’s pricing page.
Customers benefit from a user-friendly interface as well as a reliable smartphone app. This is a bonus since many of the recommendations on the list seem to excel at only one or the other.
Despite being cost-effective, Fax.Plus provides a lot of additional features for each plan. Let’s take a closer look at what each plan includes.
Free
- A small number of free pages
- Unrestricted storage
- Supports only sending faxes
- Electronic signature
- Multiple recipients
Basic
- A monthly page allowance, with extra pages charged per page
- Sending and receiving fax
- Allocated fax number
Premium
- A larger page allowance
- All features of the Basic plan
- Fax logs can be exported as a CSV file
Business
- A larger page allowance
- Several team members
- Integration with Slack
- Multiple numbers
Enterprise
- The largest page allowance
- All features of the Business plan
- Unlimited team members
- API for Fax.Plus
- Integration with Zapier
- Advanced security features
- Priority assistance
As can be seen above, the options are versatile and comprehensive. But, for a budget-friendly option, the Basic and Premium plans are the ideal options.
In terms of price, the Business plan is also fine. However, its monthly page allowance won’t work for high-volume users.
You can add a vanity fax number to your plan for a one-time fee. Signing up for Fax.Plus is free. The duration of the free plan is unrestricted. When you use up the free pages, you’ll be charged per page.
2. eFax — Most Widely Used Online Fax Service
eFax is the global leader in online faxing, with over 10 million users worldwide. It’s easy to use: send a fax online from your mobile, tablet, or computer.
The nice part? No fax machine is needed.
It’s also easy to start using eFax. Choose an area code depending on your location or a toll-free number in the United States. One of eFax’s most notable features is the capability to send a fax internationally, which is something that not every online fax service offers.
You can convert a fax number to eFax if you already have a number for your company. It’s worth noting that eFax does not support novelty or custom fax numbers.
As previously stated, faxing is widely used in situations where signatures are needed. Electronic signatures are built into eFax, allowing you to sign forms without having to print them.
eFax provides unrestricted online storage to ensure that your faxes are securely stored for the duration of your account. Searching for keywords makes it easy to find files.
In terms of security, eFax will not send fax content to your email inbox. Rather, Inbound faxes are encrypted and stored safely. As a result, you can fetch confidential faxes from there.
eFax lets you retrieve files from online cloud storage services like iCloud, Dropbox, or Google Drive and send them out through your virtual fax.
eFax now sells Personal, Business and Corporate plans. Each includes a monthly page allowance with a per-page charge above it, and annual billing costs less than monthly. Current prices are on eFax’s pricing page.
They also provide eFax Corporate solutions with volume-based pricing. You can contact their sales department for a quote.
In comparison to the competition, eFax is on the expensive side.
eFax is a common, easy, and straightforward fax service. The mobile app is sleek, and you’ll get high-quality faxes.
In terms of value for money, eFax may not be the top choice. There are cheaper solutions available, and they are not ideal for high-volume users. To see if eFax is a good fit for you, sign up for a free trial.
3. MyFax — Best Online Faxing Service For Personal Usage
If you want to send a fax from your phone or tablet, MyFax is another great choice. The simplicity of this online faxing service is what makes it stand out.
The process of getting started is quite easy. MyFax is a service for faxing via email. Recipients with online fax services and traditional fax machines can also receive messages.
While MyFax is straightforward, it falls short when it comes to security. They also don’t have a digital signature option.
As a result, I’d suggest MyFax for personal use rather than faxing company-related or confidential details.
MyFax has three plans (Home Office User, Small Business User and Power User), billed monthly or annually, each with a monthly page allowance. Current prices are on MyFax’s pricing page.
Home Office User
- A monthly allowance of sent and received pages
Small Business User
- A larger page allowance
Power User
- The largest page allowance
When you hit your limit on any plan, extra pages are charged per page.
Again, MyFax is best used for personal usage. The number of faxes you can send per month is restricted even on the Small Business and Power User plans.
For comparison, MetroFax’s top plan includes more pages for less than the cost of the MyFax Power User package. If you send a lot of faxes, you might be able to find a better deal somewhere else.
The Home Office User plan is the only one that offers a free trial of MyFax. It’s worth giving the platform a month to see if you like it.
4. MetroFax — Best Mobile Service For Faxing A Document Online
MetroFax offers great value for money when it comes to faxing a document online. It’s a great choice for small businesses and personal usage, with three plans billed monthly or annually. Current prices are on MetroFax’s pricing page.
The following features are included in all MetroFax plans:
- You’ll be able to port your current fax number
- Toll-free and local fax numbers
- There are no long-distance fees
- Send fax to multiple people at the same time
- Instant confirmations and automatic retries
- There are no long-term commitments
Metrofax has one of the best smartphone apps for online faxing. Although the web interface is a little dated, it’s a great choice for sending and receiving faxes from your phone.
MetroFax provides great fax quality. You won’t have to pay an activation fee to start using it, unlike most of the other platforms.
You can choose from three MetroFax plans.
- Essential
- Best Value
- Professional
Each plan is based on the usage limit.
Large files are also supported by the service. One of the reviews talks about how easy it was to send a 500+ page fax using MetroFax, even though other online fax services couldn’t handle it.
Overall, MetroFax is a great option for all your online fax requirements. I wish the web version was a little more user-friendly, but you’ll be fine if you use the mobile app. To see if MetroFax is the best online fax service for your needs, sign up for a free trial.
5. Sfax — Best Fax Service Online For Healthcare
The “S” stands for Secure, which is ideal for an online fax service designed specifically for healthcare organizations.
Privacy and protection are top priorities for medical records that are submitted through any means. Sfax is a HIPAA-compliant faxing service that lets users submit, receive, annotate, manage and digitally sign files without the need for a printer or fax machine.
Sfax will also enhance the healthcare workflow process in addition to providing increased security. Manually printing and signing papers is not a good use of time.
The service allows remote employees, as well as those who are traveling, to submit and receive important health documentation from anywhere.
Sfax was created with the health industry in mind, so it provides a variety of options for further control. You can provide users with different levels of access, protection, and permission.
Groups can also collaborate, export, view, and manage documents with ease.
On the same plan, you can have Sfax with multiple numbers, locations, and sub-organizations. There is no need to create a different account for each location, and the number of users per account is unrestricted.
Sfax sells monthly plans with a page allowance and unlimited users; pages above the allowance are charged per page. Contact Sfax for current prices. Here are its plans and features:
Standard
- A monthly page allowance
- You can have as many users as you want
Plus
- A larger page allowance
- You can have as many users as you want
Contender
- The largest standard page allowance
- You can have as many users as you want
Sfax also offers tailored Enterprise plans for high-volume users. Pages beyond your monthly limit are charged per page.
As can be seen above, Sfax’s pricing is on the higher end compared to the other options on the list. However, for medical practitioners or businesses in the healthcare industry, it is well worth the investment. Another downside of Sfax is that it can only send faxes within the United States and Canada.
6. RingCentral Fax — Best Fax Service Online For Solo Entrepreneurs
RingCentral made it on my list of the best video conferencing services. They also have a great fax service.
If you’re a sole proprietor or a small business owner who expects to do a little more faxing than the average entrepreneur, RingCentral Fax is a great option.
RingCentral Fax appeals to me because it has a modern UI, supports fax scheduling, and allows for large file attachments. You will not have to pay for a toll-free fax number if you use this provider.
It’s easy to start using RingCentral. Simply enter your fax number and log in online or via the mobile app. After that, you can send and receive faxes from any device.
You’ll be able to send online faxes to teams, get fax activity alerts, and block any inbound faxes without caller ID.
RingCentral Fax maintains an online log file of all faxes received and sent, making it simple to refer back to them.
RingCentral no longer lists standalone fax plans; online fax is included in its RingEX business phone plans, priced per user per month with a discount for annual billing. Current prices are on RingCentral’s pricing page.
As can be seen, the cost of additional pages decreases as you progress through the pricing tiers, which is unlike some of the other services we’ve looked at so far.
You can try RingCentral Fax for free for 30 days.
RingCentral Fax isn’t without flaws. The faxes could be of higher quality, and it doesn’t have the capability of sending international faxes. However, the plans are reasonably priced.
7. Dropbox Fax (formerly HelloFax) — Ideal For Small Groups With Cloud Storage Integration
Dropbox Fax is an effective fax service with a user-friendly interface.
The service is unique thanks to its team options and cloud storage integration, which are ideal for small businesses.
Another aspect I like about Dropbox Fax is that it has an integrated editor. This makes dealing with any attachments a breeze.
Unlike eFax, which tracks sending and receiving faxes to your monthly allowance separately, Dropbox Fax adds them all together. This is, in my view, is a favorable pricing structure.
Dropbox Fax has a free plan and three paid plans (Home Office, Professional and Small Business), each with a monthly page allowance and a set number of group members. Current prices are on Dropbox Fax’s pricing page.
Free
- A few sent pages
- No group features
Home Office
- A monthly page allowance
- A small group of members
Professional
- A larger page allowance
- More group members
Small Business
- The largest page allowance
- The most group members
The free send-only package has limitations. It’s just for people who need to send a single short fax. It’s not possible to do much with the plan.
Dropbox Fax will not charge you any setup fees.
The paid plans come with a free trial of 30 days and annual contract discounts.
Although Dropbox Fax is a great service, it does have a drawback that is difficult to overlook – there isn’t a dedicated smartphone app. However, if you can get past that, Dropbox Fax is still a viable choice.
8. Biscom 123 (now part of Concord) — Best Service For Occasional Faxing Via Email
Biscom 123 is one of the best solutions for faxing via email today.
Using the following format, you can send a fax directly from your email app:
Name.FaxNumber@biscom123.com
The email’s subject line will appear on the fax cover page as well. The memo of the cover page will be the email’s body. Apart from that, you won’t be able to change anything else on the cover.
Simply add the files as attachments for faxing via email. Attachments are converted to fax image files before being sent to the intended recipient.
When all pages have been transmitted successfully, you will receive a confirmation email.
Though Biscom 123 integrates with email, it has an odd flaw in comparison to other online faxing services. The web interface does not allow you to send faxes.
The Biscom 123 smartphone app must be linked to your existing email platforms. While using the app, you might encounter some glitches or crashes.
Biscom 123 sells monthly plans for individuals and small groups, each with a monthly page allowance and a per-page charge above it. Its prices aren’t listed on a page we could check, so ask Biscom for a quote.
Without entering your credit card details, you can try Biscom 123 on a free trial for 30 days. It’s a decent choice for casual users, but it comes with its own set of drawbacks.
9. FaxZero — Best Free Online Faxing Services (Send-Only)
FaxZero, as the name implies, is free of charge.
The platform has been used to send over 21 million faxes.
FaxZero is easy to use. Simply go to the website and complete the fax form. You don’t even need to create an account for using this service. Simply type your name, phone number, email address, and company (optional) into the fields provided. Then type in the recipient’s name and fax number.
After you’ve filled out the details, you can send a few pages by adding a file. This limit does not include the cover page.
You can send a small number of free faxes per day. That’s not bad considering you’re not paying for it.
The drawback of FaxZero is that it does not allow you to receive faxes. However, it’s ideal for the occasional usage of sending quick fax.
FaxZero also has a paid per-fax option called “Almost Free Fax.” You can send more pages with this option, and the FaxZero branding is removed from the cover page.
If it was a one-time thing, you probably wouldn’t need the paid package. For paid options, there are other services with monthly payment plans that provide much greater value and benefits.
FaxZero is the best choice if you don’t have access to a fax machine and want to send a quick fax online for free. It’s quite restrictive after that.
How To Choose The Best Online Faxing Service
With so many choices, make sure the online faxing service you select meets your unique requirements. This is the process that was used to create this guide.
Page Restrictions
There are no services on our list that allow sending and receiving an infinite number of faxes. On a monthly basis, each service and plan have its own set of restrictions.
You’ll be charged per additional page if you go over those limits. You’ll want to select a plan that fits your needs while staying within your monthly limit.
If you’re a low-volume or a high-volume fax user, there are options and plan limits to consider at various price points.
File Archives
The best online faxing services make it simple to view all sent and received faxes. As a result, look for a service that allows you to view and access old messages.
These records are sometimes only available for a year. So, before you sign up, make sure you understand how it works.
Access To Multiple Platforms
It is essential to have the ability to send a fax from anywhere if you want to get the most out of an online fax service. Smartphones, tablets, Android, and iOS devices should all be supported.
Although many online fax services have a smartphone app, there are some without it. Furthermore, some smartphone apps are better than others. There are services that have a great smartphone app but a web interface that is outdated.
As a result, you should base your decision on which faxing medium you plan to use the most.
Cloud Storage
You can still store your documents by transferring them to cloud storage platforms like Dropbox or Google Drive, in addition to archives supported by the faxing service.
Another advantage of integrating cloud storage is the capability of sending faxes from those systems. This is much more convenient than scanning, uploading, and adding documents.
Final Thoughts
The way we send and receive faxes has evolved. In both homes and workplaces, people are getting rid of bulky fax machines. The way we communicate via fax has changed thanks to online faxing services.
So, which one’s the best online faxing service? It all depends on what you’re looking for.
