Fax from Your iPhone in Safari
Open bestfax.com in any iOS browser, enter the fax number, upload your document, and send. No App Store visit, no account password — just your name and email to get started.
Quick Answer
You can send a fax from an iPhone without downloading an app. Open Safari (or any browser), go to bestfax.com, and follow the step-by-step flow: enter your name and email, enter the recipient's fax number, pick the free dedicated fax number that comes with a subscription (one-time senders may not see this step), upload your document using the standard iOS file picker, optionally add a cover page, review the preview, and pay. The fax is transmitted over the phone network to the recipient's fax machine. $4.95 per fax or $10/month for unlimited.
Key Features
Works in Any iOS Browser
Best Fax runs entirely in your iPhone's browser — Safari, Chrome, Firefox, or any other. No app to download, update, or manage. Just visit bestfax.com and start faxing.
Upload Photos and Files
Use the standard iOS file picker to upload documents from iCloud Drive, your Photos library, Google Drive, Dropbox, or any app. You can also choose 'Take Photo' from the file picker to capture a paper document with your camera.
Mobile-Optimized Flow
The step-by-step fax flow adapts to iPhone screens with an icon-based stepper, large tap targets, and a streamlined layout. No pinching or zooming required.
Free Cover Pages
Add an optional cover page at no extra cost — or skip it with one tap. Fill in your subject and message right on the cover sheet and choose from 4 styles (standard, professional, modern, classic). AI help with cover page text is also available when you send from your Best Fax dashboard.
Live Number Validation
As you enter the recipient's fax number, Best Fax checks whether it's a valid fax line. If the number is detected as a mobile line or appears disconnected, you'll see a warning before sending.
Fax Preview
Review a visual preview of your complete fax — including cover page — before paying and sending. See exactly what the recipient will receive.
How It Works
Open bestfax.com in Safari
Navigate to bestfax.com on your iPhone. The site presents a mobile-optimized interface. Works in Safari, Chrome, or any iOS browser. No app download needed.
Enter Your Details and Recipient
Enter your name and email (no password needed). Then enter the recipient's fax number — Best Fax validates it in real time and warns you if the number appears to be mobile or disconnected.
Upload, Review, and Send
If you're signing up for the $10/month subscription, you'll first pick the free dedicated fax number that comes with it — one-time senders may not see this step. Then tap the upload area to choose files from iCloud Drive, Photos, or another app. Add an optional cover page. Preview your fax, then pay ($4.95 one-time or $10/month) and send. You'll receive delivery confirmation by email.
Why Fax from Your iPhone Without an App?
Best Fax offers a straightforward browser-based alternative to downloadable fax apps. Open bestfax.com in Safari, upload your document, and send without installing software or granting app permissions. Pricing is transparent: send one fax for $4.95 or subscribe for $10/month to get unlimited faxing and a dedicated fax number. When you're done, close the tab — nothing to uninstall.
Uploading Paper Documents from Your iPhone
If you have a paper document that needs faxing, tap the upload area on bestfax.com and iOS will present its standard file picker. From there, you can choose 'Take Photo' to capture the document with your camera, select an existing photo from your Photos library, or pick a file from iCloud Drive or another cloud app. For best results when photographing documents, use good lighting and a flat, contrasting surface. You can upload up to 10 files totaling 50 MB and up to 100 pages per fax, and Best Fax will merge them into a single transmission.
Works on Any iPhone with a Modern Browser
Best Fax is a responsive web application that works in any modern iOS browser — Safari, Chrome, Firefox, or Edge. The interface automatically adapts to your screen size. It also works on iPad, where the larger screen provides more workspace. Since it runs in the browser, there are no iOS version requirements beyond what your browser supports.
Sending Faxes On the Go
Your iPhone lets you fax from anywhere with cell service or Wi-Fi. Need to fax a signed contract from a client meeting? Photograph it and send it before you leave. Need to fax a form from the pharmacy? Do it from your phone in under 5 minutes. The mobile-optimized flow uses an icon-based stepper and fullscreen views, making the process feel native even though it runs in the browser.
