I have used PDFfiller to fill out PDF forms which wow dave required my either purchasing a piece of software or otherwise some other form of complex document manipulation - PDFfiller has made PDF document handling a breeze for me.

2 things I would like to see changed. The original custom color selector was better than the these presets that are available now. The other is the sizes of the font jump by twos, an input to put in a custom font size would be great

The PDF filler worked beautifully and I like it. It was exceptional. But rather costly I could not afford it at this time. But I had no problems achieving what I did with documents I wanted to change.

What do you like best?
I love how I can neatly complete compliance filings that don't have a fillable PDF format using PDF filler. I can type on the form in PDF filler instead of having to print a hard copy and hand write or use a typewriter - who even has access to one of those anymore, lol?
What do you dislike?
It can be tricky to get the alignment just right and then save the completed document.
Recommendations to others considering the product:
Great tool for using to complete documents that don't have fillable format.
What problems are you solving with the product? What benefits have you realized?
Completing compliance filings for various States that don't offer fillable PDF forms.

What do you like best?
I like that making forms fillable is super easy and that the platform is affordable
What do you dislike?
pdfIller can be a little confusing to use, so it isn't necessarily intuitive when I'm trying to find my docs that I created versus the filled out ones that come to me
What problems are you solving with the product? What benefits have you realized?
getting forms signed remotely!
