You're staring at a document that has to move now, but the recipient still wants a fax. That's exactly the kind of annoying, real-world problem a mobile fax app free search is trying to solve. The catch is that “free” can mean very different things, from free daily pages, to a one-time starter credit, to a short trial that disappears fast. This list sorts the field by what you can do on your phone, what it really costs, and where each app breaks down in practice.
If you only need to send a few pages, the best option is the one that gets out of your way. If you need to receive faxes, keep a number alive, or handle sensitive paperwork, the free tier often stops being enough. The tools below are grouped by the way they're free, so you can match the app to the job instead of getting trapped by the marketing.
1. SendItFax
SendItFax is the easiest starting point for anyone who wants to fax from a phone without building yet another account. It supports browser-based sending on mobile, accepts common document types like DOC, DOCX, and PDF, and keeps the flow simple, upload, enter numbers, send. For people who only fax once in a while, that matters more than a long feature list. SendItFax
Why it stands out in daily use
The free tier is a real free tier, not a teaser. You can send up to 3 pages plus a cover, and the service allows 5 free faxes per day according to the provided product details, which makes it practical for short forms and one-off documents. For heavier sends, the paid Almost Free option is $1.99 per fax and supports up to 25 pages, with priority delivery and the option to remove SendItFax branding.
Practical rule: Use SendItFax when the fax is urgent, the document is short, and you don't want to hand over email details just to move one file.
SendItFax also fits the broader reality of faxing in 2025. Mobile faxing still serves a real niche, with over 48 million people globally using mobile fax apps, and the use is concentrated in document-heavy workflows where recipients still require faxed forms, signed records, or time-sensitive submissions, as described in the industry article on mobile faxing in 2025 (TechRounder). That's exactly where a no-signup browser workflow wins.
Best fit and trade-offs
The strongest use case here is occasional outbound faxing. It's also a good fit for freelancers, remote workers, and small offices that need something quick from a browser on a phone. The limit is obvious, though, it's U.S. and Canadian faxing only, and the free tier puts branding on the cover page.
- Best for: quick, no-account sends
- What works: fast mobile upload, free daily sending, no subscription pressure
- What doesn't: international recipients, heavy volume, inbound fax needs

2. FAX.PLUS
FAX.PLUS lands in the freemium camp. It gives new users a real starter allowance, but the free pages are finite, so this is best when you want to test a polished service before deciding whether it deserves a paid slot in your workflow. The app is available on iOS, Android, and web, which helps if you jump between phone and desktop.
What the free offer actually buys you
The free plan includes 10 total outbound pages for new users with no card required, according to the product notes. That's enough for a small batch of documents, but not enough for ongoing use. Once those pages are gone, the free plan is done.
Security is where FAX.PLUS looks more serious than a throwaway fax tool. The provided product details point to 2FA, encryption, SOC 2, ISO 27001, and an Enterprise path with a HIPAA BAA for regulated users. For businesses handling sensitive files, that matters far more than a glossy mobile interface.
Where it fits, and where it doesn't
FAX.PLUS is a good choice for people who want a clean app and a low-friction first send. It's less useful if you need inbound faxing, because receiving requires a paid plan. That makes it a better outbound test drive than a full free fax identity.
A free fax app that only gives you a small outbound pool is still useful, but only if you know your exact job before you start.
For people comparing mobile fax apps, this is a classic freemium pattern. It's not unlimited, but it's structured enough that you can try the app before committing. If you want to explore the product directly, visit FAX.PLUS.
3. FaxBurner
FaxBurner is one of the clearest examples of a tool that solves the receiving problem better than most free fax apps. The free tier includes a temporary fax number and up to 25 received pages per month, which is exactly why it keeps showing up in “mobile fax app free” searches. The outbound side is much tighter, so the app is more useful for receiving than for sending.
Free inbound is the main reason to use it
The free plan includes a disposable fax number, which is valuable when you need a document sent to you without committing to a long-term line. That's a real gap in the market, because a lot of free fax coverage only talks about sending. Independent reviews note that recurring free inbound options are rare, and that many free tools prioritize outbound pages while capping volume tightly. FaxBurner's free tier at least answers the “can I receive this document?” question.
Outbound is where the limit shows up fast. The free plan gives only 5 outbound pages total, and cover pages count toward the limit. That makes it poor for anything longer than a very small send.
The right use case
FaxBurner is useful for travelers, freelancers, and small offices that need a temporary inbound identity. It's also the cleanest answer when someone asks for a free fax number for a one-time form. It is not the tool for consistent business faxing, and it should not be used for regulated information.
- Best for: temporary inbound faxing
- What works: free number, easy setup, no card required
- What doesn't: very limited outbound use, temporary number, no permanent free line
- Website: FaxBurner
4. HP Smart Mobile Fax
HP Smart's Mobile Fax tile sits in a trial-based category. It's handy when you're already in the HP ecosystem, want a simple send, and don't need a full fax account. The workflow is straightforward, attach files, scan with the camera, add a cover, and track history inside the app.
Why trial-based tools still matter
A trial can be enough when you only need to fax once and don't care about long-term access. That's the main appeal here. You're not signing up for a dedicated fax service, you're using a mobile utility that happens to include faxing for a limited period in many regions.
The downside is the same as every trial. It's not durable. HP can change the offer, and the free status depends on the current promotion. That makes HP Smart better as a convenience layer than as a plan you can rely on month after month.
Practical fit
If you already use HP Smart for scanning or printing, the fax tile can be a fast detour when a fax is suddenly required. If you need receiving, recurring sends, or a stable free entitlement, this is the wrong category.
Practical rule: Trial-based faxing is best when you need one send today, not a tool you'll depend on next month.
For the official product page, use HP Smart Mobile Fax.
5. PC-FAX.com FreeFax
PC-FAX.com FreeFax is one of the most bare-bones true free options on the list. It allows one free page per day without registration, which is simple enough that it's easy to understand and hard to misuse. If you only ever fax a single page, and you can live with the daily cap, that's a fair trade.
Simplicity is the whole product
This app is not trying to be your document hub. It's trying to move one page quickly from a phone. That makes it attractive for a very specific user, someone who occasionally needs a short fax and doesn't want an account, a card, or a subscription trail.
The obvious limit is the page cap. One page per day is tight enough that any multi-page form becomes a problem. Inbound faxing is also outside the core free offering, so this is mostly a send-only utility.
Best when you know the document is short
If you're sending a signed notice, a single-page form, or a simple confirmation, FreeFax can be enough. It's not a long-term workflow tool. It's a convenience tool with a strict ceiling.

6. Dropbox Fax
Dropbox Fax, formerly HelloFax, is the cloud-first option for people who already live in storage apps. Its free outbound pages are limited, but the primary appeal is the integration story, with support for Dropbox, Google Drive, OneDrive, Box, and Evernote in the product details. That makes it less about the fax itself and more about the document path leading into the fax.
Where cloud integration helps
If your file is already sitting in cloud storage, a fax app that can pull it directly saves time and cuts errors. That matters when you're faxing the same kind of file you've already archived or edited elsewhere. Dropbox Fax also sits inside the broader Dropbox Sign ecosystem, which gives it a paperless feel that some users prefer.
The limitation is still the same as with most free fax apps, the free allotment is small. If you need an inbound number or want higher volume, you'll hit the paid wall quickly.
Good for light, cloud-native sending
Dropbox Fax works best for people who like a clean document workflow and don't mind that free use is narrow. It's not the strongest choice if your main need is receiving.
- Best for: cloud-based sending
- What works: strong integrations, paperless workflow, credible brand
- What doesn't: small free allotment, paid plans needed for higher limits and inbound numbers
- Website: Dropbox Fax
7. Snapfax
Snapfax uses a credit-based model, which makes it feel more like buying a small unit of fax capacity than joining a subscription. The app includes 1 fax credit at install, so you can test a real fax before paying for more. That's a sensible design for people who hate recurring plans.
Why credits can be easier than plans
Credit systems are straightforward when your faxing is unpredictable. You buy what you need, and you don't keep paying for a monthly allowance you won't use. Snapfax is built for that mindset, especially for occasional users who just want a one-off send.
The trade-off is that the free part ends after the starter credit. There's no ongoing free pool, and receiving requires a different service. That means Snapfax is more of a pay-as-you-go tool with a free intro than a long-term free solution.
Free starter credit is useful if you want to test transmission quality before committing, not if you want recurring no-cost faxing.
If you want to try that model, start with Snapfax.
8. iFax
iFax is a free trial choice with professional features attached. It runs across iOS, Android, Mac, and Windows, and the product details call out e-signing and document management, which gives it a broader office feel than a basic fax sender. It's one of the better names to consider when you want to evaluate a more complete workflow before subscribing.
Trial first, subscription later
The main value here is evaluation. iFax commonly offers short free trials, often around a week according to the product notes, so you can judge the interface and feature set before paying. That's useful if you know you'll need more than just a send button.
The catch is obvious. It's not an ongoing free option, and trial availability can vary by region or promotion. If you want a permanently free fax tool, this isn't it.
Who should care
People in professional environments often want more than a simple send. They want e-signatures, document handling, and cross-device access. iFax makes sense for that kind of buyer, especially if they're testing a bigger fax workflow and don't want to commit blind.
For the official site, use iFax.
9. JotNot Fax
JotNot Fax is another credit-based app, and it benefits from the document-handling background of JotNot and Genius Scan. It's a good fit for users who care about scanning quality and predictable per-fax pricing more than they care about a recurring free tier.
The scanner pedigree matters
Faxing starts with the document. If the scan is messy, the fax looks messy. JotNot's background in document capture gives it an edge for people who photograph paper forms from their phone and want the result to look clean enough to send without rework.
The app's free use is trial-dependent, so this is not a durable no-cost tool. It's better viewed as a low-friction way to test the workflow before buying credits.
Best use case
JotNot Fax works for sporadic faxing when you want a cleaner scan path than a generic fax app usually gives you. It's not built for ongoing free sends or inbound fax management.
- Best for: occasional sending with strong document capture
- What works: credit-based pricing, strong scanning background
- What doesn't: no permanent free pool, trial availability varies
- Website: JotNot Fax
10. EasyFax
EasyFax is another app that leans on pay-as-you-go rather than a monthly commitment. The product description emphasizes a lightweight model with small promotional or earned credits, which makes it appealing if you want to test the service before spending anything meaningful.
A small test first, then credits
This type of app is useful when you don't want subscription pressure but still need mobile faxing to work properly. EasyFax keeps the model simple, buy credits only when needed, and use the app's camera-to-fax flow for quick sends.
The free side is minimal, though. Expect promotional or earned credits to cover a test, not a working free workflow. Once you go beyond that, you're buying credits.
When it makes sense
EasyFax is best for low-volume users who care more about avoiding recurring bills than about getting a robust free plan. It's a better fit for a quick experiment than for a regular fax routine.

Choosing the Right Free Fax App for Your Needs
The best free mobile fax app is the one that matches the kind of fax you need to send or receive. If you want true no-signup sending, SendItFax is the most practical choice because it gives you a real free tier, a clean browser workflow, and clear paid fallback if you need more pages. If your priority is receiving rather than sending, FaxBurner is the strongest free option because it gives you a temporary number and inbound pages, which most free fax tools don't handle well.
The category matters as much as the app. Completely free tools, like SendItFax's daily free sends, PC-FAX.com FreeFax's one-page allowance, and FaxBurner's temporary inbound number, are best for narrow jobs and short documents. Tools with a limited free offering, like FAX.PLUS and Dropbox Fax, are better if you want a legitimate product to test and don't mind a small free allotment. Apps offering a trial period, like HP Smart, iFax, Snapfax, JotNot Fax, and EasyFax, are useful when you need to verify the workflow once before deciding whether to pay.
Security and compliance should come before convenience if your fax contains sensitive data. The mobile fax market still has a meaningful role in regulated and document-heavy workflows, and one industry statistic says approximately 17% of businesses globally still rely on fax for critical operations (Faxsipit). That's why the best app isn't the one with the flashiest interface, it's the one that fits your document type, volume, and privacy needs.
If you just need to send a one-off form from your phone, start with a tool that doesn't ask for a subscription. If you need an inbound number, choose the app that clearly offers it on the free tier and accept the limits. And if the fax is business-critical, pay for the cleaner option instead of fighting a free plan that wasn't designed for your use case.
