What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Very good so far except that when I attempt to print completed documents the program changes the orientation of the doc so that it cannot be printed. I've managed a work around, but it's annoying.

User friendly. In past years I've been able to bring up the forms I need from www.irs.gov and fill out the forms, save and print the forms. Same is true for Louisiana Dept of Revenue. Now neither of the websites supports filling out any forms. I was extremely frustrated with this change. PDFfiller has made my life so much easier. Thank you

PDF Filler is intuitive to use (easy buttons). The one add I would like is to be able to edit signed documents and initial the edits...currently signed documents are Read Only even to the originator.

A safe way to fill forms I wish they had an option for screenshare set up support. Though it took awhile to learn, we are so grateful for what it's allowed our company to do! LinktoFill allows us to send out one link and receive back filled PDF's instead of uploading over and over and sending back and forth to gather missed info. The site is hard to learn and takes a bit to get used to.

It makes pdf documents manageable !! Everyone has some reason to love it! You have to need it for every day utilization to deserve to buy. You can do anything on a pdf document. Of course the basic features as to sign, insert date and page number. Highlight words, insert marks, cyrcle a word or an item.Insert an image easily. More specific features: eraser tool, text box, drop down menu (for someone to choose from) and verification of the document! All languages are supported. The cost is quite salty.. and the history version is missing. Page scroll down is a bit unconvinient that wastes me time in large documents..

Love this!!! Can erase words from PDF's. You will love this program!!! There is an eraser feature that is the best thing ever. This allows you to change a PDF document. How many times do you need to modify a document, or wish it said something different, but don't have an editable version. With PDFfiller you can erase the verbiage, and replace it with something else. You can also easily place your signature on documents too. You can upload you own personal signature too.

I love not having to print forms, then fill them out and scan them. So much time, ink and paper wasted. Using PdfFiller I just upload the document, fill it out and send. Super easy.

Wish it was more affordable Works great and seems to be the only app that put everything in the proper format for editing. My only complaint is that it isn't more affordable, especially for first year subscriptions I feel like there should be a discount so that you can truly decide if spending that much at once is worth it to you and your business needs.
