I was a first time user and it was late at night and the PDFfiller.com information was a little confusing. I had problems opening the document on my computer as it was not readable. I reported this via live chat around 12:45 AM and it was resolved in about 10 mins or so. I was happy with the outcome.

At first I was a little concerned. Difficult experience in the past. More business are utilizing e-sign, Do c-section and Right signature. Nice that I can utilize this program with compatible other programs
SargeMac
The search option brought up the forms I needed. In on instance multiple versions were on different sites. I was able to bring in to the appropriate version by typing in the URL, I found that to be a real time saver.

Obviously, the sales portion of the Web site needs clarifying, but customer support could not have been more generous and quick in solving my misunderstanding. Wish all companies did as fine a job.

Best tool with advanced features - PDF Filler Add, edit, share & highlight option in one application. Easy to use and must have application if you publish documents frequently. If you work on PDF files daily it is a must have application. It handles PDF files and let you edit and add content very easily. - Easy to use tools - Add text, edit text, highlight, notes etc. many features in one application - No watermarks which makes it easy to edit and share. It is working good till now and not found any such cons in the application. Conversion of files do takes times and using advance features needs a pro in that. It gets slower with big files.

The service was great and really… The service was great and really useful! I've used it for the past year- I just didnt need it and couldn't afford it this year- the reason I'm giving 5 stars is because when I went to cancel it within a month of by mistake letting it renew- they (Jerome in the chatbox) were SOOOO AMAZING and helpful! With so many companies they completely dehumanize you and fight for ages when you try to cancel. It has given me immense respect for this company that they were kind and helpful!
