What do you like best?
I use PDFiller constantly. In some ways, better than Acrobat,
What do you dislike?
Price of a subscription. (Being forced to write 40 characters or more is absurd.) Also, the survey is too long and time consuming.
Recommendations to others considering the product:
Would be helpful if png's were accepted and converted to pdf's.
What problems are you solving with the product? What benefits have you realized?
Had one problem a long time ago, which was quickly resolved by a PDFiller staffer.

edit your PDFs as the best. 1.- It's Free. although there are some functions that are paid, for daily use just a free account which is very good. 2.- Pretty friendly and friendly interface. Everything is understandable and the use of the program is very easy to understand. 3.- Its use can be integrated with dropbox, googlr drive, box and onedrive. 3.- You can use files that are in your pc, your cloud or in some website (in this case you just have to enter the link). 4.- with the built-in editor you can add images, scratch, write in the text, delete sectors, hide words or paragraphs with black, add lines, and many other things. 5.- You can save your work in pdf, word, excel or powerpoint format. It also includes the option to send via mail, fax or simply share the link. the bad thing, is that if or if you must register to use it, which perhaps is not something serious, but the program forces you to do so.

PDFfiller has exceeded my expectations. I regularly have a need to complete and to apply signatures to PDF documents. PDFfiller is a real time-saver in that it eliminates the need to print a hard copy and then manually complete, sign, and scan the PDF documents. Also, the PDFs that it creates end up looking much tidier and more professional. As a bonus, the software saves and maintains a duplicate record of all my PDF papers. I originally subscribed to PDF Filler, under urgent circumstances, simply to be able to apply a verified electronic signature to a single document. But I've been awed by how versatile and useful it is. I now use it almost weekly. As a business owner, PDFfiller has been a great value. I'd recommend it to anyone who has an occasional or even a regular need to edit and to apply signatures to PDF documents. There's really nothing about PDFfiller that I don't like. This is highly unusual for me as I'm not the most tech-savvy person and I frequently end up frustrated with software.

It could be a little better if you put hints on tools that explained how to set and adjust them, but only if the person hovers over the tool without clicking it.

I didn't realize how much use I would… I didn't realize how much use I would make of this program, or the range of functions that it offers. I just got the free-version at first because I needed a digital signature. But now, as an academic, I find I use it all the time to share and to sign documents: now that everything is online and we have limited contact, this has become more important. I can't say that I've mastered or even noticed all the file features this program offers, but almost every time I use it I discover something new. Well worth the money!
