# Free fax online: what's actually free

You can send a fax online for free, with limits. Free services typically cap pages and faxes per day, and some print their advertising on your cover page. Others call themselves free but start a paid subscription after a trial. Here is how to tell, and when paying a little per fax makes sense.

1. Check the page limit: free tiers often allow only a few pages per fax.
2. Check what goes on your cover page: some free services add their own branding.
3. Check whether a card is needed: a free trial that asks for a card usually becomes a subscription.
4. Check what you get if it fails: a delivery confirmation and a retry matter more than the price for important papers.

## When paying per fax is worth it

For a medical, legal, tax or benefits form, a clean fax with no advertising, automatic retries and a delivery receipt is usually worth a couple of dollars. Here you pay once for that fax, with no account and nothing to cancel, and only for pages that arrive.

## Faxing from the PageFax app

The PageFax app gives every new phone one free page to try it, with no card needed. After that you buy credits that never expire, one per page, with no subscription.
