I have been sent a form as a scanned PDF (it has no fields). There are several online tools that can be used to fill it in such as FillAnyPDF.com, but these do not suit my needs. They either watermark the output or straight up charge you to download the result (note: they don't tell you this until after you've filled in your form, beware!).
Is there any free alternative? I'm playing around with Foxit but can't find the functionality I need (add text, images, save as new PDF).
