If you're searching for a way to fax from Adobe Acrobat, here's the short answer: Adobe has no built-in fax button. Not in Acrobat Reader, not in Acrobat Pro, and not in Adobe Sign. The feature simply doesn't exist.
The good news: you can adobe fax any document in under 2 minutes using an online fax service. This guide explains exactly how, what it costs, and what happened to Adobe Sign's long-removed fax feature.
Try mFax.to — upload your Adobe PDF and send a fax in under 2 minutes. No phone line. No hardware.
Does Adobe Acrobat Have a Fax Feature?
Adobe Acrobat — in every version, Reader through Pro — has no native fax capability. There is no "Send by Fax" menu option, no fax number field, and no built-in fax modem support anywhere in the application.
This surprises many users because Acrobat is the world's dominant PDF tool, and PDFs are the standard document format for faxing. The gap between "I made this PDF in Acrobat" and "I need to fax this PDF" is real — but bridging it takes only 2 minutes with an online service.
What Acrobat can do instead:
- Create, edit, and export PDFs (the format every fax service accepts)
- Apply digital signatures with Adobe Sign (distinct from faxing)
- Send PDFs by email directly from Acrobat
- Print PDFs to a fax modem driver on Windows (hardware required — see below)
Quick Answer
The fastest way to fax from Adobe Acrobat is: File → Save As PDF → upload to mFax.to → enter fax number → Send. Takes under 2 minutes. No phone line needed.
What Happened to Adobe Sign Fax?
Adobe Sign (formerly EchoSign, acquired by Adobe in 2011) did support faxing — but that feature was removed and is no longer available.
The history:
- EchoSign era (pre-2012): EchoSign allowed recipients to sign documents via fax as an alternative to e-signatures. A fax-back workflow let signers print, sign, and fax the document back.
- eFax integration: EchoSign also had an eFax integration for sending and receiving faxes alongside documents.
- Adobe Sign today: The fax feature has been completely removed. Adobe community moderators have stated directly: "the fax feature is no more available in Adobe Sign accounts." There is no way to send a fax from the current Adobe Sign Send page. Adobe has not indicated it will return.
If you previously used Adobe Sign's fax feature and are now looking for a replacement, a dedicated online fax service is the direct substitute.
How to Fax From Adobe Acrobat: 3 Methods
Method 1: Online Fax Service (Recommended for All Users)
This method works regardless of your operating system, printer setup, or whether you have a phone line. It's the approach used by the vast majority of people who fax PDFs from Acrobat.
Export Your Document as PDF
In Adobe Acrobat, your file is already a PDF. If you're working in another Adobe app (Illustrator, InDesign, Photoshop), use File → Export As → Adobe PDF or File → Save As → PDF. For best fax compatibility, use standard PDF (not PDF/X or PDF/A).
Open mFax.to in Your Browser
Go to mfax.to in any browser. Create a free account — takes about 30 seconds. No software download required.
Upload Your PDF
Click Send Fax and upload your PDF. mFax.to accepts PDF, Word, JPG, and PNG files up to 20 MB. If your Acrobat document has multiple PDFs that need to go together, merge them first with the free Merge PDF tool.
Enter the Recipient Fax Number
Type the fax number including country code (e.g., +1 555 123 4567 for US numbers). Double-check the number — a single wrong digit means a failed delivery or your document reaching the wrong machine.
Add a Cover Sheet (Optional)
mFax.to includes a built-in cover page. For a more polished result, use the free fax cover sheet generator before uploading. See our fax cover sheet templates guide for professional options.
Send and Confirm
Click Send. A delivery confirmation arrives in your email within minutes. If the receiving line is busy, mFax.to retries automatically and notifies you of the final status.
Method 2: Email-to-Fax From Adobe Acrobat
If you prefer to stay inside Acrobat's workflow, you can fax via email without opening a browser:
- In Acrobat, go to File → Send by Email (or simply open your email client)
- Attach your PDF to a new email
- Address the email to
[faxnumber]@send.mfax.to— for example,15551234567@send.mfax.to - Hit Send — the fax is transmitted within minutes
This is popular in law firms and medical offices where staff work inside Outlook all day. The fax recipient receives a standard fax on their machine; you receive a delivery confirmation reply to your email.
No Browser Switching Required
Email-to-fax lets you fax directly from Adobe Acrobat's email share feature. Attach your PDF, address it to the fax gateway, and send — without leaving your document workflow. For a full walkthrough, see our guide on how to fax from Gmail.
Method 3: Print to Fax Driver (Windows Only, Hardware Required)
On Windows, if you have a physical fax modem or a multifunction printer with fax capability connected to a phone line, it appears as a printer in Acrobat's print dialog. You can then "print" your PDF as a fax:
- Open your PDF in Adobe Acrobat
- Go to File → Print (Ctrl+P)
- Select the fax driver from the printer list (e.g., "Microsoft Shared Fax Driver" or your printer's fax option)
- Click Print — Windows Fax and Scan opens and prompts you for the recipient's number
Limitations of this method:
- Requires an active phone line connected to the fax device
- Not available on Mac (Apple removed fax modem support in macOS 12 Monterey)
- Increasingly impractical as landlines disappear — fewer than 30% of US households still have one
No Phone Line? Skip Method 3
If your computer isn't connected to a landline-enabled fax device, the print-to-fax method simply won't appear as an option — or will fail silently. Online faxing (Method 1 or 2) is the reliable choice for most users in 2026.
How to Fax From Adobe Scan
Adobe Scan (the mobile scanning app) also has no built-in fax feature. However, the workflow to fax a scanned document is straightforward:
- Scan your document in Adobe Scan
- Tap Share and save or export the file as a PDF
- Open mFax.to on your phone (browser or the mFax app)
- Upload the PDF, enter the fax number, and send
The mFax mobile app on iOS and Android makes this especially smooth — you can open the PDF directly from Adobe Scan's share sheet and send it without navigating to a website.
Adobe Fax Pricing: What You'll Actually Pay
Adobe charges nothing for faxing because it offers no fax service. The cost is entirely from the online fax platform you use to send your Acrobat PDF.
Online Fax Service
Best for most Adobe users. mFax.to weekly plan covers unlimited faxing for 7 days — ideal for sending one batch of documents. Monthly plans from $19.99.
In-Store (FedEx / UPS)
Must physically visit a store. A 10-page local fax at FedEx costs ~$15. International pages hit $5.99+. Travel time not included.
Mobile App
mFax iOS and Android app. Scan with your camera or share from Adobe Scan directly. Same account syncs across all devices.
Cost Comparison: Online Fax vs. In-Store for Adobe PDFs
| Method | Pages | Estimated Cost | Notes |
|---|---|---|---|
| mFax.to (weekly) | Unlimited | $6.99 | 7-day unlimited plan |
| mFax.to (monthly) | Unlimited | $19.99/mo | Best for regular senders |
| GotFreeFax | Up to 3 | Free | 2 faxes/day, US/Canada only |
| FaxZero | Up to 3 | Free | Ad-supported, limited daily |
| FedEx Office (local) | 10 pages | ~$15 | First page $1.89 + $1.49 each after |
| UPS Store (local) | 10 pages | ~$15.50 | ~$2.00 first + ~$1.50 each after |
| eFax | 150 pages | $18.99/mo | HIPAA option available |
For any fax longer than 3–4 pages, online faxing beats store pricing. The break-even on a mFax.to weekly plan versus a single FedEx trip is a single 5-page document.
Online Fax Alternatives for Adobe Users
Several online services compete for the "fax my Adobe PDF" workflow. Here's how they compare:
| Service | Free Tier | Starting Price | HIPAA | Mobile App |
|---|---|---|---|---|
| mFax.to | Trial available | $6.99/week | Yes (Business) | Yes |
| eFax | No | $18.99/mo | Yes | Yes |
| Fax.Plus | Yes (10 pages) | $6.99/mo | Yes | Yes |
| HelloFax | No | $9.99/mo | No | No |
| GotFreeFax | Yes (3 pages) | Free | No | No |
| FaxZero | Yes (3 pages/day) | Free / $2.09 per | No | No |
| RingCentral Fax | No | ~$8/mo | Yes | Yes |
For occasional faxing (1–3 pages): GotFreeFax or FaxZero cover basic needs at no cost.
For regular faxing from Acrobat: mFax.to weekly or monthly plan offers the best combination of price, reliability, and confirmed delivery.
For HIPAA-regulated documents (healthcare, legal, insurance): mFax Business adds BAA agreements, encryption, team accounts, and audit logs — starting at about $9/mo (billed annually). You build your own plan — pick the seats and pages you need rather than squeezing into a rigid fixed tier.
Preparing Adobe Files for Fax
Not every Adobe file format faxes equally well. PDF is the universal fax standard; other Adobe formats need a quick conversion first.
| Adobe Format | How to Prepare for Fax |
|---|---|
| PDF (Acrobat) | Ready to upload directly — no conversion needed |
| PSD (Photoshop) | File → Export As → PDF (flatten all layers first) |
| AI (Illustrator) | File → Save As → Adobe PDF |
| INDD (InDesign) | File → Export → Adobe PDF (Print) |
| XD (Experience Design) | Export artboards as PDF via Share > Export |
| Scan (Adobe Scan) | Export as PDF from the share menu |
File Too Large?
Fax services typically accept PDFs up to 20 MB. If your Acrobat file is larger — common with high-resolution Photoshop exports — use the free Optimize PDF tool to compress it before uploading. No signup required.
Faxing Signed Adobe Documents
A common scenario: you've collected signatures in Adobe Acrobat Sign, and now the recipient needs the signed PDF by fax (common in healthcare, legal, and government workflows).
The process:
- In Adobe Sign, download the completed/signed document as a PDF (Manage → select agreement → Download PDF)
- Open mFax.to and upload the signed PDF
- Enter the recipient's fax number and send
The fax recipient receives the fully signed document — with signature fields and date stamps intact — delivered directly to their fax machine or online fax inbox.
For sensitive signed documents like medical records or legal contracts, use mFax Business which includes TLS encryption in transit, secure storage, and a Business Associate Agreement for HIPAA compliance. See our full guide on how to fax medical records for healthcare-specific requirements.
Which Option Is Right for You?
| Your Situation | Best Approach |
|---|---|
| One-time fax (1–3 pages) | GotFreeFax or FaxZero (free) |
| One-time fax (4+ pages) | mFax.to weekly plan ($6.99) |
| Regular Adobe PDFs, ongoing | mFax.to monthly plan ($19.99) |
| Healthcare / HIPAA signed docs | mFax Business (From $9/mo) |
| Office with landline + fax printer | Print-to-fax driver in Windows |
| Mobile workflow (Adobe Scan) | mFax mobile app |
