What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Customer support was top notch. They resolved my print issues with my form. The reason I did not give it 5 stars and would not recommend is that I Googled for a form to fill out for a US Passport. I didn't expect to find one i could fill in on line. What was not apparent was that ONLY AFTER SPENDING 30 MINUTES FILLING OUT THE FORM did I find out I had to pay $20 to print, save, fax, email or share the form. Customer service was great, but did not want to sign up for a monthly pdf service or pay $20 for 1 form.

Love it- so easy- wish there was a cheaper option for "stay at home moms" (could verify with a phone call) - since all I tend to use it for is school forms and household paperwork

Still getting used the program but like it a lot! I love it -- it helped me fill in some VA medical forms and made them look very professional, plus I could go back and edit as needed. It also allows me to save, print, and email. There are many other features too!

What do you like best?
I use it as a healthcare EHR. Very convenient.
What do you dislike?
I only really have one complaint. When I use it to fill my PDF files, the pop up bubble gets in the way after I click a box so then I have to click somewhere else to see my next option.
Recommendations to others considering the product:
Great.
What problems are you solving with the product? What benefits have you realized?
Send to sign is convenient. Send to fax is also nice.

What do you like best?
I really like that PDFfiller is a very user friendly and employs a lot of the same standard editing tools commonly found in simple office software like Microsoft Word. It's a great step up from the standard Acrobat Reader and also has an easier learning curve than some of the more advanced Adobe PDF products. Being able to sign documents electronically is another strong feature.
What do you dislike?
When I edit a document that has more than one page, I am unable to perform a copy and paste across multiple pages, which is a bit annoying when trying to standardize items across one document. Saving documents is also very easy. We can save the document to any one of my computer folders or a cloud storage account.
Recommendations to others considering the product:
I think that PDFfiller is a very effective and easy-to-use PDF editor and converter. For the price and functionality, it's definitely worth checking out, in my opinion.
What problems are you solving with the product? What benefits have you realized?
Since we often deal with many types of text documents, especially Word documents, PDFfiller has really helped to enable conversions of Word documents to PDF, which are more ideal for certain things like printing. We can also convert PDF files to Word, which greatly reduces our need to perform time-consuming typing. In general, PDFfiller has been a great tool for working with PDF files with its intuitive interface and clear functionality.

Prompt and Efficient Response They responded to my request for chat support quickly. When on line they worked to get me what I needed. My need was fulfilled satisfactorily, even though it took quite some time. My lack of knowledge may have contributed to the length of time for the matter to be resolved. All agents were prompt.

It is useful. Only thing I would like is for it to figure out what font I had on the document BEFORE I edit it. I have contract templates that I use that I have to edit sometimes and finding the font that will match that size and actual type is very difficult. i usually end up just dealing with whichever one I find. If there is a way to do that, please let me know via email.
