extremely convenient and fairly easy to use, but i need to find time to sit down and learn more features other than just filling out forms and signing them. I think the vvalue of a yearly subscription is very good.

I wish it wasn't so expensive...I'm still on the free trial right now but this app is great. Maybe offer like a college student pricing? I know us kids in college cant pay $40 a month for it

A life saver pdfFiller has helped me to make easier my load of work and without I might be stressing a lot. What I like most about this software is the ease of use, as an educator I need to use PDF's everyday and this software helps me a lot with that. The free trial is good but then you need to pay for another features.
Allanys A.
This is the only and best website I use for all my PDF files needs. The only thing that could be better is the cost of the monthly rate. I'm on a government check and it's almost too expensive for me at this time. I hope that I can somehow afford to keep using this wonderful service, thank you so much!
Lucinda K
What do you like best? The templates are really helpful. It can automatically be saved with new information. What do you dislike? The signateure date and initialling has to clicked for each time. Would like to be able to just click the option and repeat that option several times without selecting it. What problems are you solving with the product? What benefits have you realized? Can send out contracts and paperwork. Re-formatted the paperwork to be filled out electronically and it's much clearer.

Great free software for editting PDFs Great free software for editting PDFs. Unfortunately, I could not combine files, or extract pages so I had to go back to using adobe for my business
Brandon Eddy
I am not computer techy - and I have been able to figure this out to do what we need. I am sure there are features that I have not figured out yet - but I stay very busy @ work so doing a webinar would be tricky to schedule.

This is an amazing program This is an amazing program. I like all the options it has. Merging documents together, removing pages, splitting documents, re-arranging pages. Does it all.

It met what I needed but there is a problem with text fonts. In my case I needed a specific font and I couldn't find it, it would be interesting if it were possible to include a new font.
