What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
All of my forms have looked super professional, and when I applied for my new job, the HR department thought it was going the extra mile to type out my application instead of handwriting it.

I had problems using this program. Customer support helped me to figure out what was causing the problem and fixed it. I appreciate their time and effort.

I have terrible handwriting and often end up having to tear up forms and fill them out again. Especially if the spaces provided to write information are small. This program has worked perfectly for every single document that i have used it for. Very user friendly. Aligns text precisely. Overall extremely satisfied with it.

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.

So surprised and happy to find this VA… So surprised and happy to find this VA application online and available to convert to a filler style form. Printing the document by-hand was painful and re-dos were tedious but with your program I was able to complete and annotate (where needed) the application in a legible, presentable manner. Thank you for this program.

Love, Love, Love the PDF Filler I recommend this product. This program makes it so easy to fill out any PDF. It really helps in our office for everything to appear highly professional. It is taking me awhile to learn this software, but I think that once I master it that it will be very helpful in our office.

100% felt Heard and understood I started off panicking about why I requested assistance ... but the agent assigned to me was beyond patient and kind. Her calm brought me to a place of comfort and she helped me to resolve my issue in a very timely manner. Thank you, Marie!!!

PDFfiller is a great resource for business needs and ordinary forms we use every day. I'm finding as I use PDF filler more, the more I see the value for business and tax time. I'm still exploring PDFfiller. I've not had a problem using the program and instructions are available. I have not had to call for help yet, but I know if I do I will be greeted and questions answered, very professional platform.
