What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Liking it so far. But when I'm using the eraser, line, or other tool, it automatically changes back to text add mode after saving the change I've made rather than staying with the eraser, line drawer, etc. If you did it this way b/c more users keep erasing, adding lines, highlights, etc when they intend to make only one change and start typing then nevermind. I would rather it stay with the eraser, highlighter, etc. and I'll switch back to adding text when I'm ready to do so. Hope that helps.

What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

There should not be an option for…
There should not be an option for alteration on the PDF document. For example, when I tried to type my name, I made a mistake and I back space the mistake but I ended up deleting the line on the original PDF document. A program like this should not give me the option to do that. Other than that, I felt like PDF Filer got the job done for me.

Finally! A way for me to fill things out properly without printing!
I am very happy so far with this experience because not only does it allow me to fill out pdf's online and not waste paper and look unprofessional, it allows me to CREATE a pdf in the exact manner that I want it to look. I will use it for some of my professional documents on a regular basis!

Add a one-time use subscription
Add a one-time use subscription. I feel this will be beneficial to a lot of your potential customers that do not run a business and may be using this software for personal use. I feel like a one-time 48hr subscription that can be purchased at a low cost would be profitable, especially if it can be repurchased at a later date if the user needs to use the program again. It does not make sense to offer a free 30 trial to users who are not going to use the program for more than 48 hours. I used this for free and you could have made money off of my usage by providing a one-time use subscription. Now, I have to make a new account with a different email if I would like to use your program again because I cannot afford to pay $100.00 for a subscription that I may only use once a year. So, just a suggestion.
