This is an amazing program! How many times we all have to fill out forms, even if they are pdf forms available for downloading on line) and wish we could just fill them in with the keyboard instead of printing out a hard copy and THEN handwriting our responses. PDFfiller allows you to save a pdf and then fill it in so easily. There are also a lot of options for checking boxes, circling responses, highlighting, enlarging or shrinking text size, etc. The program is user-friendly, easy to follow, print, download to your own computer and save. Just a GREAT addition to my tools. I also get such positive feedback whenever I submit a requested form---they are delighted to have READABLE information.

Over the top excellent customer service First and foremost i want to express the excellent customer service i received from Daniel yesterday evening to the wee hours of this morning. i couldn't figure out how to correct or update a form and my computer literacy was no where to be found. I ask Daniel to please have patience with me and he went above and beyond my expectations. Daniel not only spent hours on trying to help me figure out the issue he also walked me through how to send him a screenshot of the issue! Not once did i ever feel rushed or uncomfortable especially when i wasn't able to follow his instructions. He not only walked me through fixing the form; he also helped me fill in some fields i was unable to do. The most awesome experience was he stayed on the line with me the entire time!!! This is the kind of customer service that is such a rare commodity and i was blessed enough to be on the receiving end with Daniel. He is absolutely an asset to this company and greatly appreciated.Warmest Regards;Rhonda Wright
