See for yourself by reading reviews on the most popular resources:
Pretty straight forward but when you want to print multiple forms of the same type I don't see a way to easily clear the info, I have to overwrite or clear each field manually. Thank you, Fred McFaddin

easiest way to fill forms! I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares. In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need. You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

This is a great tool and is full of… This is a great tool and is full of features that I really need for editing, exporting, merging and printing documents. I like all of the supported file formats and may use the routing features in the future. The pdfFiller will import huge .pdf files and allows you to save just one or two pages from that file for editing. It offers alot of flexibility and performance features which I appreciate for document management and workflow.

Hands down best ever! This service is absolutely, hands down, beyond the shadow of a doubt one of the best services that I have ever utilized for document fill-and-sign, templates and basic document editing. I love the service, it's ease of use and especially the price point is unbeatable. I would recommend this service to any of my colleagues in law and especially in the real estate industry.

A larger number of pixels increases the resolution of the image. Keep in mind, however, that an increase in the number of pixels also increases the file size of the picture. Images with extremely high resolution consume a large amount of drive space.
