I needed PDF Filler (or something like it) for a specific purpose and for a short time. It got the job done. I was surprised to see the Annual Fee ($72.00) show up on my credit card statement, instead of the monthly fee ($6.00). I cancelled my subscription on 4/11/2016, and have been checking my statements for a refund. Am I waiting in vain?

could be better I feel that adobe does a better job at converting PDFs. Although PDFfiller has a good trial period that you can use all their resources. I like that it has a notary with the plan you choose. some documents don't fit what you search for. Conversion to PDF could be simple.

What do you like best? Ease of use, quick editing, icons help with the direction on what you are looking for. What do you dislike? Editing some previous text, automatically changes font. Recommendations to others considering the product: Best buy for your dollar. What problems are you solving with the product? What benefits have you realized? Saves time using the editor rather than print out paperwork to fill by hand.

Fairly easy to navigate Fairly easy to navigate. Text does not always line up exactly right, but close enough to make the document readable. Overall, very pleased with the service.

Great features. Easy to learn. The features I've used so far have been fantastic. pdfFiller is quick and easy to learn. The only feature it doesn't have that I would utilise is when creating a form and using the 'formula' option I'd like to be able to add formulas like in excel e.g. =field_1 so that I can duplicate a form entry where it has been entered previously. I chatted with the live support team about this and they were fast to respond & took this request onboard for future updates. A great product and fantastic customer service.
