I've only used it a few times, but I think that I might be using it more over the next couple of years, as my daughter finishes high school and goes through the college application process! She's also on a couple of sports teams which require the same forms every year; it will be nice to have the info already entered and just modify some dates!

What do you like best?
This just helps a ton when I need to edit a pdf on my computer. I used to export PDFs as a jpeg and edited the photo and it was super stupid but this is perfect because I never have to try to remember how I edited a PDF the last time I did it.
What do you dislike?
It’s a little clumsy and took a bit for me to figure it out, which means I’m not excellent at explaining how to use it to other people that aren’t technologically inclined, but it still works really well.
What problems are you solving with the product? What benefits have you realized?
I need to edit release forms and vouchers on a daily basis for my models and it’s a breeze with this extension on my laptop.

PDFs made easy Since using PDFfiller, I haven't seen any PDF I can't tackle This software allows me to edit any PDF unlike Acrobat Reader. Has other useful functionalities such as sending PDF's to clients for e-signature, merging/extracting/compressing pages as well. I do not think this software needs any improvements. It helps ease my workload immensely each week.
