See for yourself by reading reviews on the most popular resources:
I use a Chromebook. I joined a Chromebook forum And PDFfiller came highly recommended when I needed to send a fax, fast. I was very impressed with the ease of transferring a PDF file and faxing it with a few very easy steps. I've since needed it again and to happy that I had it. I will definitely be checking out other option PDFfiller has to offer.

Its a real good software, I think that people really can used it, maybe there should be a program that pay by used not a regular monthly charges. I am a every six month user.

All PDF tools in one app
My overall satisfaction about that app is a lot, it's just great tool for everyone, for students and also employees as well, at any time people can make change in their document and send it wherever it's needed.
That's basically great app, because you can solve all document issues in one app, scanning, adding image to the document putting dates, even signature, saving as pdf, or word or excel, sending to email, printing and etc. which help users to save more time.
I remember I faced problem while logging in, actually I think to login for that kind of program is something extra.

Great PDF editor!
Great!
PDFfiller is easy to use, powerful, and user-friendly. It has all the features I need.
I'd like to see more fonts so I can match the fonts on the PDF page.

Great, this time so far. I used the program a little over a week ago but my documents were messed up because I was not told I had to pay first in order to save or print the document. I had to create it all again. It was the same one as this now, 821 ssa form. It took me hours to get as far as I had.

Professional look!
Got to know about PDFfiller because we use Salesforce at work, and these two are compatible. Taken together - tremendous time savings, at least several hours a week, i'd say!
Longer contracts might need a while to get fully visible on the screen, but no rush here

It would help to have some sort of tutorial outlining the all the functions. Having been offered a webinar during the 30 day free trial would've been helpful.
2020-07-27
Super impressed by the level of support from these guys. They were on my problem within minutes and when it turned out I had the wrong level of subscription (I needed a lesser one) it was changed and updated straight-away - no questions asked. Really happy.
