What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Only used twice but each time I was pleased with the features and ease of use. The only negative is that it is difficult to save files. I had to use a two step process of saving to PDF Filler then copying to my local drive.

I use a Chromebook. I joined a Chromebook forum And PDFfiller came highly recommended when I needed to send a fax, fast. I was very impressed with the ease of transferring a PDF file and faxing it with a few very easy steps. I've since needed it again and to happy that I had it. I will definitely be checking out other option PDFfiller has to offer.

I am a new user. It seems to provide all that I need to prepare my contracts. So far so good. But I am having a printing issue with my first contract.

Ease of filling the forms. There is one change if you can make will be great... in date of birth column, once you click on it, you have to put the MM/DD/YYYY. If you can allow to override that and just put the year, that will be of help. In my case where my father was born in 1920 and his date of MM/DD is not known, I'm forced to fill it with incorrect information.

I had the wrong EIN number on a 1099-misc.and it kept rejecting it until I got it corrected which made me frustrated until I saw it was an error in the EIN given to me and then I was glad that I used the service to correct the error.

PDFfiller is great, but other free options are just as good
I love the ease of use. I have to fill out a ton of PDF files and it really made my life easier.
I don't like that it costs money. I'd rather deal with ads then pay. There are plenty of other options out there that are free and just as easy to use.

I really enjoy using PDF Filler! It offers a great variety of tools that make working with PDFs so much easier and more efficient. The features are user-friendly and save me a lot of time.
My only wish is that the monthly subscription was a bit more affordable, as it can feel a bit pricey over time. However, the quality and range of features make it a valuable tool that I keep coming back to. Overall, it's a fantastic service for anyone who works with PDFs regularly!

Excellent company. Not only does the PDF Filler work great, but when I asked for the annual fee to be refunded after I neglected to cancel my subscription, it was done so immediately and graciously.
