pdfFiller scores top ratings on review platforms
There is a learning curve that I did not anticipate since I have been a long time user of Abobe. Your Live Chat customer support staff are very helpful, knowledgable and friendly!
I tried adobe and a couple of other PDF…
I tried adobe and a couple of other PDF editors and they all had problems with tax forms. pdfFiller was flawless.
Gets the job done!
Amazing, all sorts of adjustments can be made (Text, highlight, signature, templates etc). User friendly and a simple enough design. Cheaper too! My only issue is internet connection, perhaps if it was available offline (I'm not sure if that's a feature or not), it would honestly replace Adobe Acrobat all together.
I needed to print a Medicare form. Had some issues with printing--only the part I'd typed printed. I opened the chat window. Sam responded, answered my questions quickly, sent me a screenshot of the adjustment I needed to make to the print instructions. From there, everything turned out very well. Thank you Sam!
I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.
It does what it is supposed to do
It does what it is supposed to do. I don't like having to put the 4 digit code in.....maybe that is just for trial??? Easier than Adobe.
