How to Send a Fax Free from Your Phone
You can send a fax free from your phone without signing up for a monthly plan. Most people only need to fax occasionally, and a pay-per-fax option costs nothing until you actually send.
This guide walks you through the fastest ways to fax from your phone today, including what to watch out for with services that claim to be completely free.

What 'free' really means with phone faxing
The word "free" gets used loosely in the fax app world. Some apps give you a trial page or two, then require a subscription. Others show the app as free to download but charge per fax anyway.
There is a meaningful difference between truly free and free to start. Truly free usually means one or two test pages, often with a watermark or a limited trial window. Free to start means no monthly commitment, but you pay a small amount when you actually send.
For most people, the second option is the better deal. If you only fax a few times a year, paying $2.99 for five pages beats a $9.99 monthly subscription you forget to cancel.
Faxend's Basic plan works exactly this way. You pay once, get five pages and a 30-day credit, and there is no account required. You can start at faxend.com/send directly from your phone's browser.
What you need before you start
You do not need much. Here is the short list.
- A smartphone with an internet connection (Wi-Fi or cellular both work)
- The document you want to fax, saved as a PDF or image on your phone
- The recipient's fax number, including the country code for international faxes
- A payment method if you are using a pay-per-fax service
If your document is a physical paper, photograph it with your phone's camera. Most fax apps accept JPG images. For better results, use your phone's built-in document scanner (available in iOS Notes or Google PhotoScan) to get a flat, high-contrast image.
Double-check the fax number before you send. A wrong digit means the fax goes nowhere, and you may still be charged for the attempt.
How to send a fax from your phone step by step
These steps use Faxend, but the general flow is similar across most fax apps.
Download the Faxend iPhone app from the App Store, or go to faxend.com/send in your mobile browser. No account creation required for the Basic plan.
Type the full fax number including the area code. For international faxes, add the country code at the front. Faxend covers T.38-compatible lines across 120+ countries.
Tap the attach button and select your file from Photos, Files, or your cloud storage. PDF is the most reliable format. Images work too, but make sure the text is legible before uploading.
Some situations call for a cover page, especially in healthcare or legal contexts. Faxend lets you add one with a short message. This counts as one page toward your total.
Preview the fax before sending. Once you confirm, Faxend transmits it. A single page typically arrives at the recipient's machine within 30 to 60 seconds.
You will receive a delivery confirmation. Screenshot it or save the confirmation number. This is your proof the fax was sent, which matters in legal and medical situations.

Best apps for sending a fax from your phone
Several apps let you fax from your phone. They differ mainly on pricing, privacy, and whether you need an account.
| App | Starting cost | Account required | HIPAA-ready | Notes |
|---|---|---|---|---|
| Faxend | $2.99 one-time (5 pages) | No | Yes, all plans | No subscription needed for Basic; pay-per-fax model |
| FaxBurner | Free (1 page/day limit) | Yes | Paid plans only | Good for temporary inbound numbers; outbound very limited on free tier |
| FAX.PLUS | Free (10 pages total, once) | Yes | Paid plans only | Strong international reach; free tier exhausts quickly |
| eFax | $16.95/month | Yes | Paid plans only | Strong enterprise integrations; overkill for occasional use |
| iFax | $8.33/month (billed annually) | Yes | Paid plans only | Good team collaboration features |
If you only need to send a fax once or twice, the no-account, pay-per-fax model is the most practical. Subscriptions make sense if you fax weekly or need an inbound number.
For iPhone users specifically, the best fax apps without a subscription tend to be the pay-per-fax options. They cost less overall if your volume is low.
Tips to make sure your fax goes through
Faxing from a phone is reliable when you follow a few basic rules.
- Use PDF when possible. It preserves formatting and font sizes better than a photo.
- Check your document orientation. A landscape-oriented page can get cut off on a standard fax machine.
- Avoid very dark backgrounds. High-contrast black text on white works best. Fax machines are essentially photocopiers.
- Send during off-peak hours if the recipient's line is often busy. Early morning tends to work well.
- Keep file size reasonable. Very large images can slow transmission. Compress photos before attaching.
If a fax fails, check the delivery report. Most apps tell you whether the line was busy, the number was invalid, or there was a transmission error. Retry once before assuming the number is wrong.

A note on privacy and HIPAA
If you are faxing medical records, insurance forms, or anything with protected health information, privacy matters. A lot.
Under HIPAA regulations, any service handling protected health information must meet specific security standards. That includes online fax services. Using a non-HIPAA-ready app to send a patient's records is a compliance risk, even if the fax arrives correctly.
Faxend uses AES-256 encryption both in transit and at rest. Every plan, including the $2.99 Basic plan, is HIPAA-ready. A Business Associate Agreement is available for practices that need one. This is unusual. Most competitors only offer HIPAA compliance on higher-tier paid plans.
If you need to receive faxes as well, the Standard and Pro plans include inbound fax history. The Pro plan adds a dedicated inbound fax number. You can compare all options on the Faxend pricing page.
