It think it can be very useful once I get the hang of it. Disappointed that for a yearly subscription of $72.00 you don't get access to the erase feature. This feature is even free online. Do consider and include it.

Give the trial period a go, you’ll be fully exposed to the functionality of the site. Customer support is communicative and relatively fast. The site wasn’t a fit for my personal needs, but the things that it did do, it does well. Reasonably priced also if you find yourself constantly editing PDFs.
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.
pdfFiller has wonderful support. You can email them or use a chat feature. From the chat feature, I was able to do a remote session through zoom to get my issues resolved quickly. Through email they always respond within 20 minutes. Great customer service!

Fumbling along with Adobe Acrobat or hand-writing forms was time-consuming, sloppy, and completely inefficient—especially if changes or updates were needed. We are going to continue to use pdfFiller and find additional uses for the product as our business grows.

pdfFiller saves us $100 or more each workday when you factor in employee time and supplies. The figure is probably higher than that, since the waiting time for patients not yet seen is also diminished, which keeps the patient from being frustrated and just leaving before their visit.

I needed a platform that could merge documents together, edit them, sign them, then email or fax them. Ideally, all in one. I was introduced to pdfFiller last year. So I just went and got an account for myself, and have been using pdfFiller ever since.
