Very user friendly site. I did lose my first document, since I didn't select the 'DONE' box first. Maybe just a little pop up message on how important that step is would be helpful.

So far I like it. I don't like that it saves it multiple times and when I try to get rid of the older versions it erases all. I am not sure if I am doing it wrong. Overall, I like the features. I'd like to see the rotating feature added. For instance, when you erase and add a new text, and thd pdf page is crooked, you can cut and rotate the piece to straiten it.

Pros: +Has a send to sign feature +Allows editing of PDF text +Add/Remove/Edit Fillable fields +Save forms as templates +Up to 5 users with the largest subscription Cons: -Layout is not intuitive and hard to learn, even for the computer literate -Limits merging to 5 PDFs -Limits on file size (you can't work on large PDFs) -Other minor inconveniences that slow workflow I chose PDFfiller for my small company because for the same price as one user for Adobe's similar product, I can have 5 users for PDFfiller. It definitely has some limiting factors and can be frustrating but it's the best you can get for the price. Definitely worth the time to take the free trial and see how you like it.

What do you like best? I can easily upload any type of form and start working immediately. Forms from the web, forms from vendors, Word documents, etc. I can also easily comvert to and from pdf as the form demands. Saving the document is a breeze and it is always the last form at the top when I log in again. It even reminds me if I have already started the same form again and gives me options. What do you dislike? The log-out is sometimes too quick, especially if I get interrupted on the phone. But even then, I just log back into the site and continue. Sometimes when I convert the file is in portrait or landscape, and it takes some time to change the orientation. However, once I got the hang of it, it went pretty quickly. I like the newer version better than what I used years ago. What problems are you solving with the product? What benefits have you realized? I can quickly complete forms for employment verification, DSS forms, unemployment forms, etc. I have yet to find a form I can't complete with pdfFiller. It speeds up my day and getting things accomplished as quickly as possible. It saves me, on average, 30+ minutes for each form. Thank you for making my life easier. I am always looking for things to help me help our company and pdfFiller is one such tool.

I have not even touched its full use of tools capabilities yet. Every day is a learning curve for me. Me and a friend started up plumbing and heating business and to cut back on overhead i took on the second job at night of doing the books until we can afford a book keeper. Bought the latest Microsoft Office and I am pulling my hair out doing spread sheets , invoices, job proposals, payroll and still have hardly learned a fraction of Offices capabilities. Excel,Word, One Note, Outlook, Access just mentioning the ones i use most. One thing i find hard to do is work with and understand is all the file formats and what one and when to use them. The one i use most is PDF . This program PDF FILLER has made my life so much easier and cut my time in Half. Once i put it in PDF format i couldn't Edit the work. Life is so much better I probably will not go bald now!

Twice a year I need to turn a pdf form into a fillable form. I don't need a subscription for such a minimal need. I wish there was truly a free way to do this without creating a trial subscription.
