What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I felt very mislead, I entered a lot of info onto a form and was only told when I tried to print there was a charge. There was a monthly charge shown but when I selected the monthly option the cost suddenly shot up

What do you like best?
I like how easy it is to take a PDF and be able to type what I need to, change colors and fonts
What do you dislike?
I wish that the erase tool would be able to go in different directions, not just left and right but to be able to use it more freely to erase easier.
What problems are you solving with the product? What benefits have you realized?
benefit in using this for my business is keeping documents clean and not having to print them out hand write on them scan them back in and email it, I can do it all in PDFfiller and keeps my documents clean, and is a lot easier.

A "Must have" business software. I am a partner in a CPA firm. We regularly receive emails loaded with "pdf" attachments. It's a pain to open and print each one. PDFiller makes the process as simple as can be. Simple to use. You literally drag all your "pdf" files into PDFiller and hit the merge key. Works like a charm, every time. Really can't think of anything that I don't like about the software.

Better and more powerful document management and editing on the web Editing my PDFs without difficulty This PDFfiller tool for online use is very useful since most PDF editors are paid and not all people can pay for such software. It also allows you to upload the documents you have in your Google Drive account, Dropbox and other tools I do not find you disadvantaged, because you are covering the need of users who can not afford desktop software, to edit a PDF document

This is my first experience with online documents and I had a difficult time maneuvering through the settings. Would like more information on how to use.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.

What do you like best? I like how simple it is to navigate fields. The program is really good about identifying editable fields in all documents. What do you dislike? I think they can improve the downloading/saving function. There seem to be more steps than one would expect. Recommendations to others considering the product: If you are looking for software that is simple and allows you to edit PDF files easily, this is your program. I feel the least amount of pain when renewing my subscription. For me, it is a must-have tool. What problems are you solving with the product? What benefits have you realized? Zero lag time in legal documents or any documents that require redlining, editing, etc.
