You can send a fax from an iPhone or Android phone using a mobile browser. You need a readable document, the recipient’s fax number, and an email address for status updates. You do not need a fax machine or your own fax number for an outbound send.
If the file is already a PDF, open it and check that every page is present. For paper pages, scan to a PDF. Keep pages upright, readable, and in the intended order. Check signatures and dates before uploading.
You can also upload supported images, but a single PDF is often easier to review for a multi-page document. See supported file formats for details.
In Notes, open a note, tap the attachments button, and choose Scan Documents. Capture each page, adjust the corners if needed, and tap Done. Notes saves the scan as a PDF in the note. Open the scanned PDF and use its share options to save or share the file so you can select it from the fax upload form. Apple’s scanning instructions show the current controls.
If the document is already in Files or Mail, you can use that PDF directly. Check that a multi-page attachment contains every page before uploading.
If you use Google Drive, tap its camera or scan control, capture the pages, adjust the crop and contrast, and add more pages before saving. Choose PDF as the output format, then select the saved file from the fax upload form. Google’s Drive scanning instructions cover the current steps. Other scanner apps can work if they produce a readable PDF or a supported image file.
Open the send form in your phone’s browser. Enter your email and the fax number provided by the recipient. Confirm the country and area code, particularly for international numbers. Onetime Fax uses the same starting price for supported international destinations, but the form checks number format, not provider coverage. If you need to check a destination country before paying, email help@onetimefax.com. See the country-code guide if you need help formatting a number.
Upload the file, review its pages and order, and check the total before paying. Onetime Fax charges $5 for up to 100 pages, then $0.05 per additional page. You can add a cover page when the recipient asks for one. The browser may need time to process images or large PDFs, so keep the tab open until checkout finishes.
A paid fax may still be queued, in progress, delivered, or failed. Use the status page and email to check the final outcome. If it fails, confirm the recipient’s number and review the status details before retrying. If the deadline or the recipient’s acceptance matters, contact the recipient for acknowledgment; a delivered transmission does not prove that a person read or accepted the document.
Use a device and network you trust, keep your phone updated, and remove local scans when you no longer need them. Verify the destination carefully. A secure website upload does not establish end-to-end encryption of the entire fax route. For regulated health information, confirm your organization’s rules, provider safeguards, and any required business associate agreement before using a service. Read Are Faxes Secure? for more.
Ready to fax from your phone? Start a one-time send.
Yes. A browser-based service such as Onetime Fax lets you upload a document and send it from an iPhone or Android browser.
A readable PDF keeps multi-page documents in order. Onetime Fax also accepts common image formats; review the converted pages before paying.
No. You need the recipient’s fax number to send. A separate number is needed only if you want to receive a faxed reply.
Check the final status page and delivery email. A successful payment or upload is not proof that the fax arrived.
