very intuituve. quick and easy to learn. i operate mobily so i like the fact that i can use it on any of my 4 computers any where in the world. Very easy to drop text in. I like the erase and highlight feature. I tried at least 6 other platfroms and they were too dificult to use.

I've used pdffiller almost a year. Works pretty good.
Available anywhere. Document storage is good. Login in is easy. Options are many especially what can be done after the document is finished.
Time to load documents Too many clicks (four) to get it to print. Can't arrange folders to my liking.

Communication & follow through on point.
Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and an 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 up for the 1year subscription. I contacted the help desk, and advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month.
Their reply communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month, refunded the difference $114 and cancelled my future subscription. I would happily use this again. Thank you very much.

If I had the option to put 100 stars, I would. This product is fantastic. There are small issues with reformatting, but I think the user can get over that.

Easily Add and Delete Pages From PDFs
PDFfiller has saved me a lot of time combining PDFs and adding/deleting pages. Definitely a must have software.
I like that I can easily add and delete pages from PDFs. They also make it super easy to combine PDFs together.
Overall, very happy with the platform. Might be nice if there was an option to upload and download to Google Drive.
