Filler is very good but need to upgrade with some more features like filling the gaps in a form on the same line, deleting the existing print and modify, etc.,

Very good. Easy to use. Perfect "side dish" for users who don't need full PDF Writer needs. Has just been saving me hours in handwriting out form information
2015-07-27
can be a little tricky to set up at first but I do love the ease of having a form filled out and emailed rather than printing, hand writing and then scanning to save to the cloud!

Paul was fantastic
Paul was fantastic. I have been chatting with several other people since April 3 and no one could figure this problem out. I was emailed that this issue had been referred to technical support and they could not provide adequate assistance. As I am not computer friendly, Paul was very helpful. He was very patient with me. I am extremely grateful to him for resolving this issue.

An absolute lifesaver for form completion on the fly!
PDFfiller is making it much easier for our staff to complete and customize forms that we use for client requests on a regular basis. Having a cloud/web-based solution for this makes things even more convenient!
Easy to learn, intuitive, variety of fonts available
No option for custom color matching within PDF file being edited

Easy to use, saves time
Time utilized more efficiently, forms completed with step by step guidance, simple for beginners or working late hours, most documents are available in the library, folder organization, can add signatures all in one spot.
PDF filler has a large library of documents, anyone can easily personalize templates, can prepare add signatures and finalize documents all in one step, saves time!
It does not have version history. It automatically saves all changes, however comparing to old versions has to be done through downloaded pdfs
