It's another of those *** websites that hopes to get you to pay a petty charge due to sunk cost fallacy, and then surprises you later with a much larger charge. My recommendation is to use the website, take a screenshot of the resume on the review screen, and get an image-to-text converter so you can get the file for free.
Perfectly legal, and you get to add a burden to their servers and get most of their service without paying those scumbags a penny.
If you don't want to do that, then just stay away, it is very little extra work to just look up a video on how to format it, you do about the same amount of writing either way. Whatever you do, don't give them money.
