You can send a fax from your phone without downloading an app, signing up for a plan, or owning a fax machine. If you have a PDF on your phone and a fax number to send it to, a mobile browser is all you need.
This guide covers how to send a fax from an iPhone or Android phone, how to convert a photo or document into a fax-ready PDF on mobile, and how to avoid the monthly subscriptions that most fax apps push you toward.
What you need
- Your phone (iPhone or Android)
- The PDF you want to fax — or a document or photo you can quickly convert to PDF
- The recipient's fax number, including country code
- A payment method for the pages you send
Step-by-step: fax from phone using a mobile browser
1. Open your mobile browser and go to Send Fax Online
No app installation required. Open Safari, Chrome, or any browser on your phone and navigate to Send Fax Online. The site is fully responsive and works on any modern mobile browser.
2. Upload your PDF from your phone
Tap the upload area and choose your file. On iPhone, you can select from Files, iCloud Drive, or any connected storage. On Android, you can browse local storage, Google Drive, or any installed file manager.
If your document is not yet a PDF, see the section below on converting documents on mobile.
3. Select the destination country and enter the fax number
Choose the country from the dropdown (this sets the correct dialing prefix), then type the local fax number. Double-check the number — a single incorrect digit will cause the fax to fail or reach the wrong recipient.
4. Review the page count and pay for credits
The service reads your PDF and shows the page count. You pay 10 credits per page. Credit packs start at $4.99, and credits do not expire. There is no monthly plan or automatic charge.
5. Confirm and track delivery
After submitting, you can follow the fax status in your fax history. Status updates from queued to sending to delivered. You receive delivery confirmation once the fax reaches the recipient's fax machine.
How to convert a document to PDF on your phone
On iPhone
- Word or Pages document: Open in the app, tap the share icon, and choose Print. Then pinch-open the print preview to open it as a PDF, and share it to Files or another location.
- Photo or scan: Use the built-in Notes app to scan a document with your camera. Tap the camera icon inside a note, choose Scan Documents, and save the result. Then export the scan as PDF.
- Email attachment: If you received a document by email, tap and hold the attachment in Mail, then choose Quick Look and share it as a PDF.
On Android
- Word document: Open in Google Docs, tap the three-dot menu, and choose Print. Select Save as PDF as the printer.
- Photo: Use Google Drive on Android — tap +, choose Scan, take a photo, and the app saves it as a PDF automatically.
- Any file: Many Android devices can "Print to PDF" from the share menu. Look for a Print option and select Save as PDF instead of a physical printer.
Should you use a fax app or a browser?
Most fax apps available on the App Store or Play Store are subscription-based. They require you to sign up, verify your identity, choose a plan, and often assign you a dedicated fax number you may not need. If you only need to send one document, this is unnecessary overhead.
A web-based fax service is better for occasional use:
- No app to install or update
- No account required to start (you can upload and preview before paying)
- No subscription or automatic renewal
- Pay only for the pages you send
The trade-off: if you need to receive faxes regularly, a subscription-based app with a dedicated incoming number may be a better fit for that specific workflow.
Common mistakes when faxing from a phone
- Uploading a screenshot instead of a PDF: Screenshots are not always accepted and the resolution may be too low. Convert photos to a proper scanned PDF.
- Missing the country code: If you only enter the local number without selecting the correct country, the fax will fail or go to an unintended recipient.
- Password-protected PDFs: These cannot be processed. Remove the password protection before uploading.
- Sending a photo of a document instead of a scan: A clean document scan is much more readable on a fax machine than a photo taken at an angle or in low light.
