This has been a life saver, because of small changes that I have to make I don't need to go and buy the 40 pack of forms, envelopes, etc. This is perfect for a small job.

It would be easy and helpful to implement: A tool which allows you to pick the colour you want (and be able to use that colour to erase, paint and write). A auto text-detector and erase

Very helpful tool for 1099. How do you auto populate though. I find it tedious to manually type the same info over and over. Still WAY better than the alternative though. Thanks.

What do you like best?
I like the choice of fonts because one can add changes or complete empty fields to a pdf and by using a different font from the original text it is clear that the additions are different from the original.. Also I like that one can add circles, check marks, "X" to a doc. And can erase portions of text.
What do you dislike?
I dislike that you have to pay extra to add or subtract pages from a pdf.
What problems are you solving with the product? What benefits have you realized?
My hand writing is very poor. So I use PDFiller to compensate for this deficiency..

so far what ive done with the PDFFILLER so far has been complicated rather its been simplistic in a professional manner. By choosing simplistic is meant as negativity rather the layout is made up for every skill level accomplish individual task. with that said give it a try Im confident it will meet ones expectations!!!

I've just been persuing the many option PDF Fill offers regarding editing pdf documents and everything is clearly labeled, explained, and easy to use. I love the level of freedom and opportunities to customize almost every aspect of the pdf. They offer templates and make it seamless and very practical to make any form a pdf, and the attention to detail in providing you additional features and options to ensure quality presentation is awesome.

I received pdf's from an online class that the asked me to print out, complete, scan back. I just did not want to print mostly but the entire process ... you know. pdfFiller helped out a lot, especially with the symbols (might want to add music notes).

I am a Landlord and own several properties I am a Landlord and own several properties. I previously have used DocuSign to obtain a tenants signature on a tenancy agreement. PDFiller is so much more flexible and would give google all the stars they deceiver for this product. Many Thanks. Franz.

user friendly and practical, what would really differentiate would be the possibility to use the app when offline and automatic synchronization once online.
