I felt misled at first feeling I needed to purchase the pdf filler after I had already used it. The customer support team replied quickly and resolved my issue.

I've tried a lot of online PDF programs, which have been extremely slow or not as advertised. PDFfiller is by far the best online PDF editing program on the market. With all the of available features, it made the decision to purchase this one over others that are similar very easy. The program is very easy to use. Some of the chrome extensions took some time to work properly but the support desk was helpful. I'd recommend this program.

That i was able to fix and remove… That i was able to fix and remove unwanted documents to send just what i needed. The fact that I can fax without having a big machine to do, matter of fact that is one of the reasons that I decided to use pdfFiller. You make filling out important documents easy and able to sign by uploading just a picture of the signature needed. However you could make it easier to be able to create a fax sheet more personal. The one on the website is okay but not personal enough. Maybe I will think about doing the annual thing let's just see what more I can learn to do with your program. thank you for making it so easy to send important documents from the comfort of my home office without having to pay someone else to fax for me

I had to use as a one -of to sign a document, but inadvertently signed up to a subscription. The website itself wasn't too clear, so no marks there. However, once i realised i was signed up and contacted the company via email, it was resolved with 2 emails over 2 days - from *********! And with me using my son's email address and forgetting i had done so. Very happy to get a refund. ******, *********

What do you like best? The tools are easy to find in PDF filler. What do you dislike? It is sometimes difficult to execute certain tasks when the pre-highlighted boxes appear. What problems are you solving with the product? What benefits have you realized? I have learned how to use it better, which has negated some of the issues. It is a helpful tool for a job that requires me to fill out many PDF documents.

It works great and I had 1 slight problem It works great and I had 0 problems until I had to sign up for a subscription before being able to download the very important documents I had started. Would be better to let people know beforehand unless I, myself, didn't see such thing.
