EASY TO USE, TRULY ALLOWS ONE TO EDIT PDFS. I WOULD LOVE TO SEE MORE FONTS AND THE ABILITY TO SET THE FONT SIZE MANUALLY, AND SMALLER THAN SIZE 8. OTHER THAN THAT, GREAT, USEFUL APP.

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!

The Product concept is very nice the use of tools are simple. Things that I don't like are is that you are required to select Continue in Browser when click the Hyper Link, this for me is an unwanted and in needed step. The App I wish would allow you to search your fillable files, without the Link/Code or QR code you cannot use it. Would be more willing to use the App if this was a feature.

I love it but when I was trying to edit document I could only click and erase some fields. I had to use the eraser for the rest. But overall great product.

This system is amazing, but I have trouble with the 40 per month fee, but I will notify my supervisors at the business, it would be a great investment for the company as a whole.

What do you like best?
I like being able to edit and/or fill-in .PDF documents. I also like that I can retrieve documents that I have previously worked on.
What do you dislike?
I'd like to be able to change the font in the text option, as it doesn't always look right if mismatched.
Recommendations to others considering the product:
I'm not sure how I first heard of PDF FILLER, but am I ever glad that I found it. My advice would be to try it out and see if it suits your needs. I like many of its features, especially the left pane that shows the document pages, and the ability to select only those that you want to include in a print or save maneuver.
What problems are you solving with the product? What benefits have you realized?
One use that I have for the program is for one of our telecommuter workers - so that she can enter details on employee time cards, and it looks better than handwriting in notes. Uploading the documents she needs is a breeze, and the program alerts me to activity, for example, when she emails the documents to us for distribution.

It has been simple, free, extremely valuable as a meeting planner being able to take copious amounts of data and be able to edit and compile it in one place.

I found myself trying to rate it 4… I found myself trying to rate it 4 stars, but it's honest about what it is- a robust, web-based pdf editing tool that doesn't try to be more than it is, and does what it is supposed to do very well.
