Works great with laptop, but Was time consuming and difficult to work on IPad. Had to switch to my laptop in order to speed up the process and complet the job.

2 things I would like to see changed. The original custom color selector was better than the these presets that are available now. The other is the sizes of the font jump by twos, an input to put in a custom font size would be great

Slick tool. Nice editing capabilities. Some of the menus are confusing - for example: finding where to update an existing link to fill document is challenging.

I'm learning how to use the program. We need it for online school for our granddaughter
It is a bit complicated. As we learn to print and save and figure out which document it which, it will be easier to use

I love this product, it is readily available on the internet can work a handful of pages to correction without downloading this software.
Cant think of many cons it works best for me to do my general corrections, might not have detailed features for a professional editor, but definitely works for me.

Logging issue troubleshoot
I was having issue logging into pdfFiller with the password that I remember, at the same time could not receive any email to reset my password. Harmhon, the live chat agent from pdfFiller, has patiently understand my situation. Although most of the time is user's issue that they don't check on junk mail or they have some instruction/rules listed in their setting. But Harmhon is able to figure that my email address was actually not being whitelisted in your company whitelist. That being said, after Harmhon inserted me into the whitelist, i am able to login without any issue again. I really appreciate Harmhon's patient and service. He is definitely a precious asset to pdfFiller! Keep up the good work!

I reviewed this software for my company…
I reviewed this software for my company (we historically use another product) for function and usability. It is significantly more user friendly than the others that do similar functions. What makes this a good decision is the cost and the support. It costs a third of the software we currently use and when I experienced a problem (on the weekend) I had (professional and personal) support online in less than a minute. Very satisfied.

Trial Offer
We were reviewing this application and thought we had agreed to the trial offer. Actually, we didn't want the trial offer. When sending an email to their support team, they immediately responded and took care of our request, no questions asked.
