What you need before you start
Online faxing is simpler than most people expect. You do not need a phone line, a fax machine, or even an account in some cases.
Before you open your browser, gather three things. First, the document you want to fax, saved as a PDF, Word file, or image. Second, the recipient's fax number, including the country code if it's international. Third, your own email address, so you can receive a delivery confirmation.
That's genuinely all. No special software. No printer drivers.
Step-by-step: how to send a fax online
Open faxend.com/send in any modern browser. You will see a clean form. No account creation is required for a one-off fax on the Basic plan.
Type the full fax number, including the country code. For a US number, that looks like +1 followed by the 10-digit number. Faxend supports T.38 protocol over VoIP, so international delivery works the same way as domestic.
Click the upload button and choose your file. PDFs render most reliably. Word documents and common image formats are also accepted. The file is encrypted immediately on upload using AES-256.
You can type a short note that appears on a cover sheet. This is useful when sending to a shared fax line at a medical office or law firm, so staff know who the document is for.
Faxend sends a delivery receipt to your email. If the fax fails, you'll know within minutes rather than hours.
On the Basic plan, a one-time $2.99 payment covers up to 5 pages. No subscription is started. Click Send, and the fax is typically delivered in 30 to 60 seconds for a single page.
That's the entire process. Most users finish in under two minutes on their first try.

How to send a fax from an iPhone
If you prefer your phone, Faxend has a dedicated iPhone app. Download it from the App Store and the experience mirrors the web version.
The app lets you pull documents from Files, Photos, or iCloud Drive. You can also scan a paper document with your iPhone camera and fax the scan directly. No printing required.
For a detailed walkthrough of the iPhone-specific flow, see the guide on how to send a fax from an iPhone. It covers camera scanning, document picker quirks, and notification settings.

Accepted file formats and page limits
Faxend accepts PDF, DOCX, DOC, JPG, PNG, and TIFF files. PDF is the safest choice because it preserves fonts and layout exactly.
Page limits depend on your plan. The Basic plan covers 5 pages per fax. Standard gives you 20 pages per month. Pro is unlimited, which matters for large contracts or medical records.
A few practical notes on file prep. Avoid scanned images with very low resolution — anything below 200 DPI tends to produce blurry output on the receiving fax machine. Black-and-white documents fax better than color, because traditional fax machines print in grayscale anyway.
File size is capped at 25 MB. In practice, a clean PDF of 10 pages is usually under 2 MB, so this limit rarely causes problems.
When HIPAA compliance matters
If you are sending patient records, lab results, insurance authorizations, or any other protected health information, HIPAA compliance is not optional. Faxing PHI over a non-compliant service can result in significant civil penalties under the HHS HIPAA Security Rule.
Faxend is HIPAA-ready on every plan, including the $2.99 Basic tier. AES-256 encryption covers data in transit and at rest. A Business Associate Agreement is available for practices that need one on file.
This is one area where Faxend differs from some competitors. Several services restrict HIPAA features to their most expensive tiers. Faxend's approach means a solo practitioner sending an occasional referral letter doesn't need a $30/month plan to stay compliant.
If you are curious about receiving faxes securely as well, the article on how to receive a fax online covers inbound fax numbers and storage.
Which plan fits your situation
Choosing the right plan comes down to how often you fax and whether you need an inbound number.
| Plan | Price | Pages | Inbound Number | HIPAA |
|---|---|---|---|---|
| Basic | $2.99 one-time | 5 pages, 30-day credit | No | Yes |
| Standard | $9.99/month | 20 pages/month | No | Yes |
| Pro | $19.99/month | Unlimited | Yes (dedicated) | Yes |
The Basic plan is ideal for someone who faxes once or twice a year. No subscription starts, and the credit lasts 30 days. The Standard plan suits small offices that send a handful of faxes each month. Pro is built for anyone who sends and receives faxes regularly, since the dedicated inbound number means clients and partners can reach you directly.
Full details are on the pricing page.

Tips for a successful first send
Most failed faxes come down to a handful of avoidable mistakes. Here are the ones worth knowing before you hit Send.
- Double-check the fax number. A single wrong digit means the fax goes to a stranger or nowhere. Read it back against your source before confirming.
- Use PDF when possible. Word documents can reflow on conversion. A PDF locks the layout.
- Send during off-peak hours for busy lines. Hospital and government fax lines can be engaged during mid-morning. Early morning or evening sends often go through faster.
- Check your spam folder. Delivery confirmation emails occasionally land in spam, especially on corporate email systems with aggressive filters.
- Keep pages under the plan limit. If your document is 6 pages and you're on Basic, the send will fail. Upgrade or split the document first.
One more thing: if the recipient says they never got the fax, ask them to check their fax machine's memory. Many office fax machines hold received faxes in memory when paper runs out, and staff don't always notice.
International faxing works in 120+ countries via Faxend's Sinch backbone. Include the full country code in E.164 format, for example +44 for the UK or +49 for Germany. The ITU E.164 standard is the reference if you're unsure how to format a number.
