What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It's been a little bit slow and clunky and doesn't always do what I expect, but I managed to figure out a lot of features I need, and it works well for me, for the most part.

Simple and versatile. Since it is new "technology" for me, I must use it with some guidance to understand all its utility, so the tutorials that are included will be handy without having to go to school to learn it.

PDFfiller is a great tool to use for editing and templates
PDFfiller allows me to utilize the same forms frequently. As a result, templates or refillable forms ensure document preparation is quicker and more efficient.
Cloud security, ability to easily create templates for commonly used forms, flatten forms after fields filled in when saving to hard drive, in PDFFiller form remains in tact and is editable for reuse, and menu set-up.
I wish PDFfiller would add the ability to add pages to a documents and allow downloading of templates created. Currently, in personal account, PDFfiller allows emailing to recipient to update information in fields, but doesn't allow me to download my template to my hard drive.

No single docs (only trial). Unable to split the file.
Despite having a free trial it would be nice to edit and download a single document. This only confuses people and catches you if you forget or are unsuccefull with cancelling within 30 days. I used this site to edit an evacuation plan and it was very easy to do, tools are good. However even with help of customer support still not able to split the plan for seperate sections of a building. I had to rewrite the pdf but I didn't make the plan myself. Overall decent tool for free 30 days but can be better.

Pre Employment Applicaiton
I work in HR and needed help with setting up an application to generate the same information such as name, DOB, etc on all pages to save time. Rep Kara was amazing! She was able to use my application and turn it into a pre-fillable form. Kara also provided me instructions on how to set up what I needed.

AMAZING FOR ALL OF YOUR DOCUMENT NEEDS.
I have tried many pdf editors as I work with several different forms in the Real Estate Industry. Pdf-filler takes the cake by far! It is simple, easy to learn, and has an entire library of ready made forms. This is my go to for any and all of my document needs.

I needed to use the service for an application
I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in.

Daniel
I was disappointed to find that PDF filler had automatically charged me for a subscription I did not agree to. I felt very stressed when I saw the sum of money that had left my account this morning. I contacted the helpline via the chat service they offer on their website and I spoke to daniel. He was extremely efficient in his help and immediately refunded my payment and canceled my subscription. I would like to leave a 5 star review for the customer service I received despite my initial disappointment in PDF filler.

pdfFiller is user-friendly and the site is easy to navigate. I love the fact that a function stays the same until you change it, eg. a font size and format. However, I would like the option to use all the Fonts that I have installed on my own computer. When a page is duplicated, I'd love it if the 'changes' made to the original using pdfFiller, could also be duplicated rather than simply a duplication of the original document. I also can't seem to find a way to cut and paste text to apply it in a different area of the document, which means that the process of replicating a change is more time-consuming, but this could be my current unfamiliarity with the software. I was impressed that within a couple of hours of use, I was offered the option to attend a webinar to improve my understanding.
