editing document is fine. Underlining is hard to figure out. Simply saving for future use (not exporting) is not clear but I stumbled on a solution that I hope will work.

Easy to use & Quick
My business is all about paperwork. Everything is time sensitive and I could not get things done without PDFfiller. I use it daily. The ease of use is so important to me. I don't have time to learn difficult programs.
Easy to upload docs from anywhere, rearrange pages, make corrections, save as PDF and save or email. You can name your files and go back to them when needed. The dashboard is easy to navigate. I have used this software for years and they are always improving and adding new features.
I have had trouble uploading an occasional document but customer service fixed the issue each time. Sometimes my document is too large which is frustrating, they have a size limit. Also, a document with signatures from another software company (e-sign) sometimes don't come thru.

Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.

I cancelled the subscription 11/11/2021 and pdffiller took my money via PayPal at 11/12/2021. I don't understand why. It's no honest. I don't even have an account on your site
Edit: I'm very satisfying with customer service of pdffiller. They returned my money. Thank you

Has worked perfectly fine with editing non-fillable pdf forms. No issues with saving in various forms to my computer. Works just as expected.

The experience is great because there have been some documents that I needed to change, but for the free trial I wasn't expected to get charged at all. It's free for a reason. That's all apart from that, it's a great tool to have.
