What Is HelloFax? Its History, Rebrand, and What It Became

If you're asking what is HelloFax, the short version is that it's not really called that anymore. HelloFax was one of the first browser-based fax services, and if you remember using it years ago to sign a lease or fax a form to an insurance company, you're not imagining things. The name is still floating around in old bookmarks and search results, but the product behind it has changed hands and changed names at least twice.

The short answer: HelloFax became Dropbox Fax

HelloFax launched in 2011 as a Y Combinator backed startup built around browser based faxing and e-signatures, at a time when most fax services still required a phone line or a physical machine. It grew alongside a sister product called HelloSign, which handled electronic signatures, and the two were run by the same company.

In January 2019, Dropbox announced it would acquire HelloSign, the parent company of HelloFax, in an all-cash deal reported at $230 million, and the acquisition officially closed that February. HelloFax came along as part of that deal, since it had always been bundled with HelloSign's e-signature and document workflow products. In 2024, Dropbox finished folding the brand in, and HelloFax was officially rebranded as Dropbox Fax, with HelloSign becoming Dropbox Sign around the same time.

The old hellofax.com domain and app.hellofax.com login still work, they just redirect or route into the Dropbox Fax product at fax.dropbox.com. So if you're searching for HelloFax today, what you're actually evaluating is Dropbox Fax.

What changed, and what didn't

According to reviews that have tested the current product, the rebrand was mostly cosmetic. The underlying service, including fax numbers, the web app, and integrations with Google Drive and Dropbox itself, stayed largely the same. What changed was the URL, the wordmark, and the fact that fax is now marketed as a feature inside a broader e-signature suite rather than as its own standalone brand.

That's also why some people report confusion: the website still references HelloFax terminology in places, which can make the transition feel incomplete even years after the name change.

How Dropbox Fax (formerly HelloFax) works today

If you sign up now, this is roughly what you get:

• Free pages on signup. New accounts get 5 free pages with no credit card required, though this is a one-time quota rather than a monthly allowance, and it does not renew.
• Pay-as-you-go option. A single fax of up to 10 pages costs $0.99 without a subscription.
• Home Office plan. At $9.99 a month you get 300 pages, which works out to roughly 3.3 cents per page, plus your own fax number.
• Cloud integrations. You can fax a file straight from Dropbox, Google Drive, Box, or OneDrive without downloading it locally first.
• Editing and signing. Because it sits under the same umbrella as Dropbox Sign, you can edit and sign a document in the same interface before faxing it.

Where it falls short

A few limitations show up consistently in independent testing:

• No dedicated mobile app. Everything runs through the browser, email-to-fax, or the Dropbox ecosystem, with no native iOS, Android, or desktop app for faxing specifically.
• HIPAA isn't automatic. Self-serve plans don't come with a published BAA, so anything involving protected health information needs a higher tier or a direct request.
• US and Canada only for number porting. If you want to move an existing fax number in, that option is currently limited to those two countries.
• Support is a web form. There's no phone line or live chat on standard plans if something goes wrong with a transmission.
• The free quota doesn't reset. Once you've used your initial free pages, every fax after that requires a paid plan of some kind.

When you just need to send one fax

If your situation is a one-off, a signed form for a mortgage lender, a referral for a doctor's office, a document for a government agency, setting up an account with a monthly plan or navigating a rebranded product can feel like more work than the actual fax. That's the gap SendFax.me fills: pay-as-you-go per-page pricing with no subscription, and the first fax is free. You can upload a PDF or image, fill and sign a document right in the browser, add a cover page, and send to any of 150+ countries from a regular browser tab.

If you fax more than occasionally, you can also receive faxes with a dedicated fax number, send faxes straight from your email inbox, keep a contacts book for numbers you use often, schedule a fax for later, and get a delivery confirmation with a transmission report so you have proof it actually went through. None of that requires guessing which rebranded version of a tool you're supposed to be using. New users can see exactly how it works by sending their first fax before deciding whether to sign up for anything at all.

For developers: skip the web portal entirely

If you're building this into software rather than sending it yourself, a browser-based fax portal, whether it's Dropbox Fax or anything else, isn't really the point. Electronic health record systems, pharmacy software, legal ops tools, and logistics platforms need faxing to happen automatically, without a human uploading a file. For that, SendFax.me offers a REST fax API that sends a fax with a single POST request, gives you real-time status through webhooks, and lets you generate API keys straight from your dashboard. Volume credit packs start around 4 cents per US page, and the full documentation is at sendfax.me/developers if you want to see the request format before you commit to anything.

The takeaway

HelloFax isn't gone, it's just wearing a different name after two changes of ownership and branding. If you're already deep in the Dropbox or Google ecosystem, that continuity might matter to you. If you just need to get one document faxed today without opening a monthly plan, or you need faxing wired into an app your team already runs, there are more direct paths than sorting out which version of a rebranded product you're supposed to sign up for.

One small related note: if you run any kind of service business on the side and want visitors to your site to get answered even when you can't pick up the phone, agentika.me is a 24/7 AI assistant widget from the same team that answers questions and captures bookings automatically, which pairs well with the kind of admin-heavy paperwork that faxing usually involves.
