What's the best free app to modify pdf files on android?
So not just viewing a pdf file, but actually making changes in it, like
filling out a form with additional information.

Filling out forms is not "modify" - it is just filling out a form in the
PDF and storing the result.

 
Modify has the general meaning of "making changes" as one of its
connotations. So if you change anything about a pdf file, like filling
a pdf form, that can be understood as modification.

Yes, but you do *not* change the PDF itself. You just enter something in
form fields provided in the PDF. And you can then save the PDF with the
filled form. But when you open it again you will see, that the form
fields are still there and can be changed again - but nothing else,
since you will not change the PDF.

It's like filling a form on a website - you do not change the website
itself just by filling a form and sending it.
