PDF Filler Signature function is great
PDF Filler is pretty good, the ability to edit pdf's is always good but I have found the Signature copy function particularly useful over the standard PDF tools.
Pdf filler is better than Adobe
Good for small simple doc editing. Adding signatures etc.
I was able to get my docs edited and printed with my native software and android phone. Adobe is too picky about using their product only, with PDF filler I was able to get everything done non issues.
It was a trial basis for free, I wish they would have told me that from day one to save me the hassle of going back to purchase, but really it didn't matter.
Hi Team, All Good but sometimes it works very very slow and have improved a lot in compare to previous years as i am using since 3 yeras in a row down the line.
What do you like best?
I like that making forms fillable is super easy and that the platform is affordable
What do you dislike?
pdfIller can be a little confusing to use, so it isn't necessarily intuitive when I'm trying to find my docs that I created versus the filled out ones that come to me
