Form was simple enough. I don't like the fact that when you reach the end you have to pay for the darn thing! Please disclose that information up front will ya!

Comprehensive, efficient and intuitive functionality. The only capability I missed was use of the arrow / scroll keys. A simplistic and refreshing technical experience. Thank you!

This is a good app. It could be improved with navigation that's a bit less clunky - more intuitive. I also wish there was a way to fill out forms without having to recenter, re-size, re-font the text so it looks normal in the document.

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.

The PDF filler worked beautifully and Loved it. The PDF filler worked beautifully and I like it. It was exceptional. But rather costly I could not afford it at this time. But I had no problems achieving what I did with documents I wanted to change.

I used the trial version of PDFfiller… I used the trial version of PDFfiller for 30 days and it did exactly what I needed. I intended to cancel my subscription on day 30 before I was charged because at the moment I only needed it for one task. They charged me on day 30 but I emailed support and they immediately refunded my money with utmost courtesy. I will DEFINITELY use their product in the future and pay for a full subscription should I have further need for their product.Steve

What do you like best? I like how easy it is to upload documents and make the necessary changes to the documents that require modification. I have completed forms for students and uploaded signatures easily and have been able to successfully download documents as well. What do you dislike? I have noticed that sometimes when I upload a document that I previously edited using PDFFiller, it makes my signature super bold and not easily read. It changes the format automatically and I have to download a new document to upload and add a signature. It seems like once I utilize PDFfiller and download the document the format of the previous e-signature is no longer compatible. What problems is the product solving and how is that benefiting you? We had to provide e-signatures to international students on their I-20 documents and PDFfiller has been an integral part of that process. It has been very accommodating for me to upload documents and sign them electronically for students and then easily download them and email them back to the students.

What do you like best? That I can mark up any pdf or create 1 new document from several. Also digital signatures, I work remotely and need this! Being remote, I need to be able to create or sign a form from anywhere and I can easily with pdf filler. I love the share feature as well, I can work on my end and my co-workers will have it almost instantly without having to print, scan and email. I work remotely, almost all from my laptop with no printer. This allows me to work from my phone or tablet seamlessly as well. What do you dislike? Not much, no complaints yet. Maybe the layout? Like where everything is, I click on the documents and then you have to specify where something is. Maybe a more organized folder system? When I share them, they should all be in the share folder, but for some reason, they're not always there. I am a very organized person and like everything in its own folder or file. I'd like a way to save everything to its own file and be able to find them quickly and easily. Recommendations to others considering the product: This is a great program, especially if you work remotely, highly recommend it! What problems are you solving with the product? What benefits have you realized? 1099 tax reports, our software only supports e-file and we are so small that we don't have that. I also love the share part, I'm able to work on my end, share it with my co-workers and they can have it almost instantly without printing and scanning, etc. I also love that I can take a few different documents and combine them to one, that is a great feature!
