easiest way to fill forms!
I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares.
In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need.
You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

The experience was good, glad to be able to complete a 'Regie du logement' lease online and to maintain our paperless way of working. The text box takes more time than I'd like to align.

BEST all-in-one Platform for business and personal use!!!
I am in LOVE with this app!! This platform provides an all-in-one service for a price you just cant beat. Without a doubt the #1 MUST-HAVE business tool that trumps all the rest. They even offer Monthly or Annually subscriptions giving the user some flexibility pricing to choose what suits them best based on their individual or professional needs. Absolutely worth every penny!!

What do you like best?
I like how easy it is to upload documents and make the necessary changes to the documents that require modification. I have completed forms for students and uploaded signatures easily and have been able to successfully download documents as well.
What do you dislike?
I have noticed that sometimes when I upload a document that I previously edited using PDFFiller, it makes my signature super bold and not easily read. It changes the format automatically and I have to download a new document to upload and add a signature. It seems like once I utilize PDFfiller and download the document the format of the previous e-signature is no longer compatible.
What problems is the product solving and how is that benefiting you?
We had to provide e-signatures to international students on their I-20 documents and PDFfiller has been an integral part of that process. It has been very accommodating for me to upload documents and sign them electronically for students and then easily download them and email them back to the students.

Simple tool that increases productivity in office
I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office.
My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed.
I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.

Good company with awesome products. Also, I even tried once to get a job as a product designer, but no luck. But that didn't change my attitude towards their digital products.
