See for yourself by reading reviews on the most popular resources:
It was a huge help on a critically important document. It was a downloaded pdf that I had to annotate, but Acrobat Pro was unable to edit it because Livecycle Designer was required. PDFfiller allowed me to do it entirely online and then print out. the required hard copy It was a godsend!

Good service but some things like filling out spaced letters are more difficult than they should be and paying for the service feels bad.Overall good though, being able to sign online is a nice convenience perk.

Manage and edit your PDF easily and quickly.
pdffiller is a pdf processor quite different from the others, you can not only convert your files from pdf to other formats (and obviously from word, excel and others to pdf), but you can directly edit and process your texts online, so which you can write about the document, underline, place images, delete phrases and all the other things that a word processor allows you to do.
Another advantage and surprises that you have, is that you can use files that are not only on your hard drive, but you can also use files from the web (through the address of the document) and you can integrate pdffiller with some app that you use daily as google drive, box, one drive and others.
Finally, a very remarkable feature is that once you finish editing the file, you can choose some classic options such as the format in which you save it, but it also gives you the option to share it via mail, print it, send it by fax and use it in some social networks like facebook.
Even if it is a bit strange, I miss the function of compressing the files, because whenever you add images to some document, the weight of the file increases a lot and makes the handling of the file more difficult. Besides that, there is nothing more to comment.

Outstanding online rep answered my questions.
I reached out to one of your online chat support reps and was giving all the information needed to help me with my court brief that I'm writing. Dee sent me sample screen shots that helped me tremendously in a few areas. You got a good employee there. You should give the guy a raise.
