I had trouble with saving files but I figured it out. The program comes with alot of different features and a webinar to see how it all works would be great.
2018-01-31
I have been using this program for almost 2 years now and it is amazing! I have uploaded all of my work documents/forms so I no longer have to hand write every single thing. Not to mention I am saving money by not having to purchase any paper and more importantly I don't have to purchase any printer ink.

Best tool with advanced features - PDF Filler
Add, edit, share & highlight option in one application. Easy to use and must have application if you publish documents frequently.
If you work on PDF files daily it is a must have application. It handles PDF files and let you edit and add content very easily.
- Easy to use tools
- Add text, edit text, highlight, notes etc. many features in one application
- No watermarks which makes it easy to edit and share.
It is working good till now and not found any such cons in the application. Conversion of files do takes times and using advance features needs a pro in that. It gets slower with big files.

Great for PDFs!
PDF filler is a great way for me to edit PDFs that clients send me. It is also very handy for finding my own PDFs that I need for a variety of reasons.
I love how useful this product is. It is also really easy to use once you get the hang of it. The database of forms they have to search and use is also incredibly helpful!
It can be a bit hard to use at first, especially if you aren't familiar with PDFs. I typically have to train an employee for about 30 minutes before they can really understand and use all of the features that PDFfiller provides.

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.
