Love it. It's the BEST thing that has happened for my business! PDF Filler has allowed my company to go almost completely paperless. Thanks PDF Filler.

Mostly good - had a little difficulty when the app decided I could only answer 1 category when I needed to respond to all 5 subcategories of a question. Also, messed with the date - it changed to a different format.

After some heartbreak at having lost the doc I was working on, the team at pdffiller managed to retrieve it for me. All those tears later, I am ecstatic to have my hard work not be for nothing!

A "Must have" business software.
I am a partner in a CPA firm. We regularly receive emails loaded with "pdf" attachments. It's a pain to open and print each one. PDFiller makes the process as simple as can be.
Simple to use. You literally drag all your "pdf" files into PDFiller and hit the merge key. Works like a charm, every time.
Really can't think of anything that I don't like about the software.

PDF filler has been a true hero for me and my daughters competition projects and has placed first!
It is very easy to use and convenient! I love how there are many options for fonts and sizes and how easy it is to print the document and save it!
Sometimes when I print out the documents it is really tiny and hard to read. This is the only con to using this product that I can think of.

Keep up the great work team

This is a very good pdf creator
This is a very good pdf creator. Relatively straightforward to use. I just don't need this functionality right now, and the team was super helpful and fast in responding to my request. They're good people!

Accidental annual subscription
I had accidentally signed up for a 1-year subscription and PDFFiller were very very friendly and ended the contract for me after all and refunded my money straight away.... I think any other company would have left me out in the cold and kept my money, because it was obviously my mistake with the forgotten cancellation... really a big thank you and also for the fact that the support took care of it so quickly. I have never experienced anything like this before.Thanks a lot again

Free trial
Edit: I appreciate the clarification and the time they took to reply to my initial review about the free trial. I will give it a go now and happy to leave it at 5 stars.
Cheers!
