pdfFiller scores top ratings on review platforms
I have found forms through PDFfiller that I could not locate anywhere else--wonderful tool!
It's fairly intuitive, but there are some cumbersome issues related to printing--too many steps--could be simplified.
So far it's been pretty good although I haven't figured everything out yet as far as the features but I'm working on it. I like it so far though for what I needed it for. I will continue to pay for my subscription and continue using the service. Thanx your service has been and will continue to be a BIG HELP to me.
Really wonderful app
Really wonderful app! It gives you the possibility to edit every element of the PDF you need - from the text (with its exact font) to images and more. I`m really very satisfied with it!
Easy to use
Easy to use. Has an issue with locating my document on my device when done. Took a few minutes to find it in downloads instead of documents.
Took a little time to figure out how to…
Took a little time to figure out how to do more than one signature on a single document, but the Support Team was helpful and patient with me as I learned.
I didn't realize how much use I would…
I didn't realize how much use I would make of this program, or the range of functions that it offers. I just got the free-version at first because I needed a digital signature. But now, as an academic, I find I use it all the time to share and to sign documents: now that everything is online and we have limited contact, this has become more important. I can't say that I've mastered or even noticed all the file features this program offers, but almost every time I use it I discover something new. Well worth the money!
