The short answer
Oh Fax works in Safari, Chrome and other mobile browsers. Your phone's file picker lets you choose a PDF saved on the phone or in a cloud folder it can open.
- Price: $2.00 per fax by card, for a PDF of up to 100 pages and 25 MB. No account and no subscription.
- Where: fax numbers in the US and Canada only.
- Send-only: Oh Fax sends faxes. It cannot receive faxes or give you a fax number.
- Not for patient data: do not use Oh Fax for protected health information (PHI).
- Refund: if the fax cannot be delivered, you get a full refund and the reason.
Steps
- Get the document onto your phone as a PDF. On iPhone, the Files app or the Share › Print › Save to Files option can save a PDF; on Android, use Print › Save as PDF.
- Open app.ohfax.com in your phone's browser and choose the PDF.
- Enter the US or Canadian fax number.
- Pay $2.00 by card. Apple Pay or Google Pay may appear in Stripe Checkout when your device supports them.
