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.

It served my purposes
It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes.
It's a good tool.

Payment issue dealt with swiftly
After both my cards being declined to register my subscription, I went onto the online support chat. Kara was super helpful and quick to deal with my issue - very professional and friendly. Kara was very generous in giving me three free days and advised within that time to try my payment again after 24 hours. Thank you Kara for taking the stress away and resolving my issue fast. Morven

A solid editor with a very minor flaw imo
Other than a better scroll bar for the area of the documents being edited, the interface is pretty easy to navigate if you have used any similar programs (such as adobe acrobat reader). I wish there was a less feature oriented version that was free to use/download, perhaps with a daily/weekly task limit, similar to things like smallpdf.

I signed up for a trial. I'm so happy to purchase it. I love it and it has made my business processes move much quicker than printing a form, completing, scanning, send it back, and storing a copy. Excellent!
