PDFfiller is a very helpful tool. However, I do feel there are aspects that could be improved. For example, it would be useful to be able to fill in ovals.

I was desperately trying to edit a pdf copy of the P&S and we could not convert it to a Word document. Finding your website where I could make edits to the form, made my life a whole lot easier. However, I work for a law firm and we normally do not have to do these types of documents. So I am afraid I will have to cancel once the document is finalized. At least, I will keep your website as a place to go to if there is a future need. Could you please cancel my membership after the 30 days I already paid? Thank you.

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.

Working Experience With PdfFiller i am using this software for about 8 to 9 months. the best thing i found in this software was its feature to send the file online without makuing sure to save first and then send. other feature i liked the most is that i can easily edit the pdf format by using this software. it is really very favorable feature to avoid the conversing to word file for editing. in my opinion, there must be improvement with the font size of editing text to make it more compatible with text. i face a problem to make the ediding in the same font size . Althorugh, it is same as that of text but it seams different. it makes the file less professional.
