Fax apps for occasional use?

I only need to fax a few times a year. Are there iPhone fax apps suitable for occasional use?

I don’t fax often either, so flexibility was important to me. Some apps require long subscriptions that don’t make sense for rare use. I found helpful insights in https://geekflare.com/software/best-fax-iphone-apps/. The article compares fax apps for iPhones in 2025, including options suitable for occasional faxing. From my experience, choosing a pay-as-you-go or flexible app is ideal. It lets you fax when needed without ongoing costs. For light users, the right app makes faxing simple without unnecessary commitments.
