I love the ease and speed I can convert docs to fillable pdf files. I am not so happy with repeatedly being asked to rate the features, take a survey and attend a webinar.

desde un inicio debería estar la indicación de que la aplicación es de pago para contemplarlo, en cuanto el funcionamiento es excelente, solo tengo duda acerca de la leyenda de que solo 5 documentos... al día al mes o a que se refieren? agradezco de antemano su atención.

Creating Fillable pdfs has never been easier PDFfiller is a software that any human resources analyst needs to learn how to use, it really sets you appart from other professionals. For me it has been the best way to automate several processes at work. I absolutely recommend it. PDFfiller is incredible, it has allowed me to create fillable pdf forms to submit them to new recruits in our company, and that way we have reduced a lot of paperwork since all of our personnel files are in digital format. Also when interviewing for a position we have been able to automate and rank our candidates via our fillable forms. I gotta admit it took me a while to fully master this software, I would love if it were a bit more streamlined, but after I got the hang of it this software really changed the way I work

Work and Study Budy Overall I love the app and all the features it offer! The benefits totally outweigh the cost. Amazing app! What I like most about the feature is I can use it both for work to fill out pdf files and for my personal studies where I can write notes, comment, add highlights and more to the file. What I least like about this is it can be a bit pricey to maintain especially if I were only a student. But good thing I am also using it for work so I can really maximize its use.

easy to upload signature I really like the option of uploading my signature and saving it, and using it over and over again from within the system (something that Docusign does not allow).

While Pdr Filer is a great tool While Pdr Filer is a great tool. Customers should be given some type of training before they use the program. There are many features that are not being utilized because I don't how to they work or that they exist.

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.
