After my terrible experience at PDFfiller, I ended up here. This service worked well, created a better-looking PDF than the one I'd made at PDFfiller, and, best of all, this site is clear about what is free and what is not. You get 3 free downloads per month, I believe, and after that you would have to pay.
This is a totally appropriate way to offer a service, provide a free element, and eventually gain paying customers instead of sending angry people fleeing from you. Well done!
Tip for consumers: This is a fine choice. You can edit your pdf and retain your sanity.
