I am pleased that I can resend my document to a recipient because I initially documented the recipient's email address incorrectly. I was able to find out how to do this with all the helpful tabs and support information

I am glad to have this service available. The use is a little awkward ... hard to navigate between pages. Wish it was easier. I do like the ease of accessing and saving documents from the website to my computer.

Very useful. Some issues with mobile devices filling out fillable forms and not all the data showing up on the completed form. Loading times could be a little faster. Also, I shouldn't have to give the app approval to access my email each time I upload a new file from my gmail account. Once should be enough, and the connection should be remembered, but it's not.

So far I like it. I don't like that it saves it multiple times and when I try to get rid of the older versions it erases all. I am not sure if I am doing it wrong. Overall, I like the features. I'd like to see the rotating feature added. For instance, when you erase and add a new text, and thd pdf page is crooked, you can cut and rotate the piece to straiten it.

Made filling out forms easy without the hassle of physically filling anything out and submitting to places in person. I can just email whatever documents I make from pdffiller directly to where I need. Thanks, PDFfiller!

This application saves me significant amounts of valuable time in the clinic
The most desirable feature of this application is the time that it saves on recurrent clinical and axillary paperwork for my clients
The most tedious aspect is searching for past documents which dont seem to search by just part of the title
2017-10-02
It is a little difficult to figure out how to load an existing form with the saved name. I also had to Google how to enlarge the font. Most of the help directions are outdated, but I did finally figure it out after a lot of wasted time. I DO like the program in general and love being able to convert and save in a different format.

This is a life changer
This is a life changer! didn't even realise it was possible to directly type into PDF forms, this has made things so much easier!

What do you like best?
The ability to send PDF's for signature and manipulate fields...
What do you dislike?
sometimes the automatic field mapping can be quirky and when people sign documents it may not be the most intuitive set up.
What problems are you solving with the product? What benefits have you realized?
Having to print out paper to just to sign and scan back. Also, due to the pandemic and less people having in person meetings this can be used to sign documents even when you are not face to face with clients.
