Quick answer: The easiest way to fax a PDF is with an online fax service — no machine or phone line needed. From your phone, open the Municorn Fax app, start a new fax, attach the PDF from your files or cloud storage, and send. You can also email the PDF through a service like EveryFax, or use a fax machine if you have one. Here’s each method, step by step.

PDFs have been a popular format for organizations for many years, and for good reason. Whether you’re filing your taxes, sending a resume and cover letter to apply for a job, or sending sensitive medical information, the easiest, fastest and cheapest way to send a PDF securely is with an online fax service.

Online fax services today make it easy to send a PDF to any fax number from your computer. Many providers also offer mobile apps that turn your smartphone into a portable fax machine, giving you more flexibility and functionality than a traditional fax machine.

Here’s how you can use your computer or mobile device to fax PDFs.

How to Fax a PDF Using a Mobile Phone

You can avoid fax machines and computers altogether by using a faxing app to create and send PDFs straight from your phone.

  1. Download a faxing app on your mobile device

    Look for a reliable app in the app store. Municorn Fax is built for exactly this, and you can see how it compares to the alternatives in our top iPhone fax app review.

  2. Get your fax ready to send

    Go to the ‘New Fax’ section of the app, where you can enter the recipient’s fax number, add a cover page, and most importantly, add an image or document to your fax.

  3. Add your PDF file to the fax

    To add a PDF to your fax, make sure the document is saved on your device or in cloud storage. Select the option to upload documents from your phone, iCloud, Google Drive, or any other major cloud service. Most modern fax apps can connect to these cloud storage services to find any PDF file on your device.

  4. Hit send when you’re ready

    Review your fax and all the details that go along with it — if you’ve uploaded multiple pages, you can reorder them as needed. Once everything looks good, press the send button. You’ll receive a confirmation and a push notification once your fax has been successfully sent.

Faxing apps are very easy to use and come with flexible monthly subscription plans – with Municorn Fax you can even send a free test fax before you subscribe. These apps are one of the fastest ways to fax PDFs, and with strong security features, they’re also a safe way to send sensitive or confidential documents.

How to Fax a PDF Online With Email to Fax

Faxing PDFs via email is similar to faxing from your phone — just find a reputable online fax provider and have your files ready.

  1. Create an account with an online faxing service

    A web platform like EveryFax lets you send PDFs and a wide range of other file formats as faxes. To get started, visit the website and create an account. With these services, you can even send faxes directly from your email, turning your email service into a fax machine!

  2. Get your fax ready to send

    When using an online fax service that integrates with your email, start a new fax by entering the recipient’s fax number in the ‘To’ field of a new email, then add @send.everyfax.com if you’re using EveryFax.

  3. Add a PDF document as an email attachment

    This is the same process as attaching any other file in an email. Simply attach your PDF to the email and hit send, and it will be sent as a fax to the number you specified.

  4. Send and confirm receipt

    The provider will then convert your PDF into a fax and send it to the recipient’s fax number. Once the transmission is complete, you’ll receive an email confirmation.

An email to fax solution is a great way to fax a PDF, as it only requires an internet connection — no fax machine or phone line needed. You can also receive incoming faxes directly in your email inbox, as these email-to-fax services are compatible with all major email providers.

How to Fax a PDF Using a Fax Machine

While many have moved to mobile or online faxing services, you can still fax a PDF using a fax machine if you have access to one.

The process will vary depending on the machine. For modern machines, PDF documents can often be uploaded and converted directly to fax format without needing a scanner. However, older machines may require you to print your PDF documents first, then load them into the document feeder or scanner.

  1. Prepare the fax

    Plug in and connect the machine, then prepare your cover page. Enter the fax number — remember, for traditional fax machines, you must verify that international fax numbers include the correct country code (faxing apps typically handle this for you).

  2. Upload or scan the PDF

    If you’re using an older machine that doesn’t accept digital files, print the PDF onto paper and feed it into the machine. Alternatively, for modern fax machines, you can upload the file directly from your computer or a memory stick.

  3. Review your fax and send

    Once you’re ready and have entered the correct fax number, send the fax and await confirmation of delivery.

While the majority have transitioned to online fax services and apps, it remains possible to fax a PDF the traditional way if you have access to a fax machine!

How to Create PDF Files

Sometimes you may need to fax a PDF but don’t have the documents in the correct format — maybe you have paper documents or files from Microsoft Word or Excel that need to be converted to PDF. Fortunately, there are many easy ways to scan, convert and create PDFs online or through popular apps.

Turn a paper document into a PDF

If you have a physical document that you need to convert into a PDF, this can be done with your mobile device or a scanner. A scan or a phone photo is worth one extra step before it goes anywhere: run it through our fax optimizer, which converts it to the black and white a fax actually transmits and shows you the result first.

  • Using your mobile phone. The simplest way to scan and fax a document is with a fax app that has a scanning feature, such as Municorn Fax. Otherwise, you can download a dedicated scanner app or use the built-in technology on your phone, such as the Notes app on iPhone. With all of these the process is simple — point your camera at the document, and your device will capture it and save it as a PDF file.
  • Using a scanner. If you have access to a physical scanner, place the paper into the scanner tray and follow the user interface instructions. Most modern scanners, especially those that are part of multifunction printers, can save scanned documents as PDFs. Just be sure to select the PDF format in your scanning settings.

Frequently Asked Questions

Can I fax file types other than PDFs using online fax services?
Absolutely. Most online fax services are very flexible in that regard. In addition to PDFs, you can easily send Word documents, Excel spreadsheets, and even image files – so you can fax what you need without having to convert everything to PDF first.
How secure is it to transmit sensitive information through an online fax service?
Online fax services are secure. They often use encryption to protect your data as it’s sent, and many, Municorn included, follow industry standards and regulations such as HIPAA for healthcare information, so you can be sure your sensitive documents are protected.
Is it possible to receive faxes on my mobile device with an online fax service?
Yes. Most online fax services and mobile apps let you receive faxes on your smartphone or tablet. Just like your email, you can view, download and organize your received faxes.
What are the costs involved in using an online fax service?
Most services require a subscription, though some charge a pay-per-fax fee. The cost depends on the provider and plan, but these services are far more affordable than a traditional fax machine and dedicated phone line. Municorn Fax plans, for example, start at $9.99 a week for unlimited faxing.
