It's a good program, convenient, relatively easy UI. Needing to subscribe to a function that was free for a time on the Adobe software, is an irritating feature of life in the 21st century.

Experience of using PDFfiller Great! Accessible on my phone and laptop. I can work pretty much anywhere. The customer service could be better and help things. I would like a direct line to expedite matters and had to reach out in email.

PdfFiller ou rien Très bonne expérience. Au début j'avais un peu de mal mais tout est venu très vite. Je l'utilise essentiellement pour ma paperasse professionnelle avec les administrations lorsque j'ai besoin de signer.Non seulement on fait des économies de papier mais en plus si on n'a pas d'imprimante ou qu'on se trouve sur le mobile ou la tablette on peut utiliser cette application. C'est top ! Pas besoin d'avoir un logiciel qui prend de la place dans l'ordinateur ou autre. Pas de risque de chopper un virus en téléchargeant !Facilité d'utilisation hors normes ! Je ne vois aucun point faible pour le moment. Si c'est le cas j'en ferai part.

Just retired and pdfFiller saves the day. Just retired and found several entities I need to work with to get all my personal business done still require faxing and filling out lots of documents. pdfFiller has help me out immensely with the modification of scanned documents and the ability to fax them...

Quality customer service I would like to say that pdFiller is a platform business that cares about their customers ! And offers assistance and support quickly and efficiently. We will continue to recommend them foe this reason.

So far, so good So far, so good. Does as it claims to.Some of the functions e.g. merge could have more accessible controls (you have to gone into a few menus), but when found they do their job well.Maximum document size is 25Mb so if you have a bigger document you have to use another online splitter and go from there. Don't really see why that functionality could be integrated though.
