PDF Filler-Sign, Send and Relax
As a user of PDF Filler, I have found I can do so much and I try to when put to the challenge. I have many ways to adjust files and docs to my needs or the needs of my Agency or Management. My fault lies in my own lack of knowledge sometimes or my being scared to try to edit or sign something. Yet I can do so much more than I actually have to it amazes me. It is nice when I have to work on the go and don't have a lot of traditional options as i would use before-print, fill, sign,fax-etc. Stuff like that. I get great simplified organization here and it is right on point.I will keep growing and using this over time.
It is the only way to play for me with needing to sign documents while on the go or out of my home area. Today with covid-19 shutdowns, I am at the mercy of technology more than ever.And I am not the tech type guy. I have to try, fail, try again and learn if all is well. Sometimes, I will get a document on my mobile that says sign and send back right away. I get confused on my Google options, other things I use and I have 2 phones and can easily get lost on both. PDF Filler works so easily and involves virtually nothing.
I still get lost at times or can't get what I am aiming for on one of my personal devices. That is my error. The interface and expansions and lack for separate software actually are great here. Least liked features or issues are at my own fault here. It is pretty solid.
Good Features and Functionality
I have used this software app for every type of editing, creating, and converting imaginable and have yet to have something it couldn't do.
You can use the software for almost any kind of pdf editing, plus document type conversions. It is very easy to use without much training or help.
The most recent update added a step to get to your full document list. Wish they would have left it at the original dashboard where all your docs appeared without the extra click.
