There is no fax app that sends unlimited faxes for free forever, but you can still fax at no cost if you keep it small. Free tiers, free trials, and pay per fax apps all let you send without paying up front. Our top pick is Faxend, the fastest way to send a fax from an iPhone, though a truly free unlimited option does not exist.
The Honest Answer About Free Fax Apps
Here is the straight answer. No fax app lets you send unlimited faxes for free, forever, with no catch. What exists instead is a mix of free tiers, free trials, and pay per fax apps that ask for nothing up front.
When I tested the current crop, free almost always came with a limit. A page cap, an ad on your cover sheet, a daily send ceiling, or a trial clock. That is not a scam. Sending a fax to a real machine costs the provider money on every page, so someone has to cover it.
If you only need one or two faxes, you can do it without paying. If you fax regularly, a cheap pay per fax app usually beats chasing free limits. I break down every genuinely free option in our guide to truly free fax services.
How I Tested the Free Options
I did not rank these from a spec sheet. I installed each app, sent real faxes to a machine I control, and watched what happened at the free boundary.
For each service I checked five things. How many pages you get before paying. Whether a watermark or ad rides along. How fast the fax landed. Whether the free path needs a credit card. And how clearly the app tells you the moment it starts charging.
If a free fax app asks for a credit card before your first send, treat it as a trial, not a free tier. Read the renewal terms before you tap accept.
The apps that scored best were upfront about pricing and did not hide a subscription behind a free button.
The Best Apps to Fax for Free (or Close to It)
No single app wins for everyone, so I ranked them by who they fit best. The table below shows where each one starts free and what happens after.
| App | Free to start | Best for | After the free part | | Faxend | Yes, free to download | Sending a fax fast from an iPhone | Per fax or plan pricing | | FaxZero | A few pages a day with an ad | A one off fax from a computer | Paid send removes the ad | | GotFreeFax | A few pages with a cover ad | Quick no account send | Small per fax fee | | Fax.Plus | Free trial pages | Trying a full featured service | Monthly plan after the trial |
Our top pick is Faxend, the fastest way to send a fax from an iPhone. Faxend, our own app, is free to download and turns a photo or PDF into a fax in a couple of taps. You are not signing up for a subscription just to see if it works, and there is no ad stamped on your cover page. Sending a fax uses credits or a plan, so it is not unlimited free, but for phone faxing it is the smoothest path I tested.
FaxZero and GotFreeFax are solid when you are at a desktop and only need a page or two. Both stamp a small ad on the free cover sheet. Fax.Plus is worth a look if you expect to fax often and want a trial before committing to a plan.
Faxend is our top pick for sending a fax from an iPhone. It is the app we build, it is free to download, and it turns a photo or PDF into a fax in a couple of taps. Per-fax or plan pricing applies.
Where Free Ends: The Subscription Wall
Most fax apps are free to download and free to open. The wall appears the moment you hit send on anything beyond the free allowance.
Some apps show the paywall honestly on the send screen. Others let you scan, arrange, and preview a fax, then ask for a subscription right before it goes out. That timing is not an accident. You have already done the work, so you are more likely to pay.
Knowing where the wall sits helps you plan. If you fax twice a year, a per fax app keeps money in your pocket. If you fax weekly, a low cost monthly plan is usually cheaper than repeated single sends. I compare the genuinely free tiers side by side in our best free online fax services roundup.
What Free Fax Apps Actually Cost You
Free is rarely only about money. When an app does not charge cash, it usually charges in another currency.
The common trade offs are ads on your cover sheet, a watermark on the pages, a hard page cap per day, and slower or lower priority delivery. A few free web tools also keep your document on their servers longer than you might like, which matters if you are sending anything sensitive.
None of these make free fax useless. They just mean you should match the tool to the job. A simple form to your kid’s school is fine over an ad supported free send. A signed medical or legal document deserves a paid, secure path. You can see how the paid options stack up across our fax service reviews.

Frequently asked questions
Not in the unlimited sense. No app sends unlimited faxes for free forever. You will find free tiers that cover a page or two, free trials, and pay per fax apps that are free to download. For a one off fax you can avoid paying, but regular faxing eventually costs something.
It depends on the service. Most free web tools cap you at around three pages per fax and a few faxes per day. Free app tiers are often limited to a small number of pages before a subscription prompt appears. Always check the current limit, since providers change it often.
Many do. Free web faxing tools usually stamp a small ad or their branding on the cover sheet, and some apps add a watermark on the free tier. Paid sends remove it. If a clean, unbranded cover page matters, budget for a per fax or plan option.
For iPhone, our top pick is Faxend. It is free to download and turns a photo or PDF into a fax in a couple of taps, with no ad on your cover page. Sending uses credits or a plan, so it is not unlimited free, but it is the smoothest phone option I tested.
Be careful. Some free web tools store your file longer and do not offer encryption or a signed agreement. For medical, legal, or financial pages, choose a paid service with clear security terms. Save the free tools for low risk documents like simple forms.
