Building home as GC and have to sign or initial many PDF files. PDFfiller has really helped. I also like the way my signed docs are kept by the app.

Loving the tool. It would be great if you could add an eye dropper feature so that if I alter text or numbers that are over a color background I can erase the copy fill in the area with the original background color and then revise the copy over the background fill

It's great to be able to fill out any pdf online. It looks so much more professional. I find the site to be very intuitive and self-explanatory. I've been able to figure out everything I needed just by doing it. I wish the subscription wasn't so expensive though because I don't feel I can afford it. The free trial is a great introduction.

PDFfiller for the win!!
PDFfiller for the win!! Of course, I've enjoyed avoiding filling out forms by hand and being able to create & save legible documents I can duplicate and email. But tonight, PDFfiller LiveChat surprised me! They helped solve a document problem for my daughter's online university application. The application program wouldn't let her upload her SAT scores, or continue her application until they were loaded! The website kept saying the 2-page file was too big!? So I loaded it onto PDFfiller, and got a helpful LiveChat rep, who quickly compressed the file for me. Voila, it worked!! PDFfiller, you just saved the day!

This app is great
This app is great. I wish there were more affordable options. I have used it a lot recently but this will not be normal. But it would be convenient to use sporadically at a lesser cost.

Satisfied but no longer need service
I have been satisfied with the subscription and have used it with my work, however I am retiring the end of September and will no longer need this subscription

If it were possible to drag and drop email addresses from my email to the pdf filler I believe it would be easier. I'm writing them down currently and then typing in the information.

This has been a lifesaver for me. I have several contracts with jobs that I am doing. To be able to fill out contracts, questionnaires, job interview questions and send project proposals has been amazing. THANK YOU FOR THIS APP!
