What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
2 things I would like to see changed. The original custom color selector was better than the these presets that are available now. The other is the sizes of the font jump by twos, an input to put in a custom font size would be great

PDF Filler has been extremely easy to use and navigate. It has all the features that I need to fill out pdf forms. I've been using the service for over a year now and have never had any complaints.
2018-11-12
What do you like best?
I like the ability to send to sign documents the most. I use it in my business daily. I like the features to organize my documents and to make templates. The templates are a life saver. Also, PDF filler has a large library of documents, anyone can easily personalize templates, can prepare add signatures, dates and finalize documents all in one step, saves time, LOTS of time!
What do you dislike?
I like it all. I don't have any complaints.I have used other document signing programs and they are way more difficult to use. No so with PDFfiller. The mobile app is not that easy to use as the (desktop) version. If I had to say Sometimes there is a delay from screen to screen. But that could be connection.
Recommendations to others considering the product:
If you need a document editing tool that does everything you can think of USE PDFFILLER it ROCKS! If you need to use this product to mark up documents and sign, try this product! I like to keep everything that I do 100% electronic, so with products like this, I am able to do so.
What problems are you solving with the product? What benefits have you realized?
I can get leases and contracts signed very easily. I like the ability to get clients to sign contracts and leases on their mobile phones. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.

What do you like best?
I can remove text with the delete button rather than having the use the eraser tool
What do you dislike?
If I delete all of the characters from a text box, I have to put a space for it to stick; I can't add or drag in other pdfs to merge them. I have to merge them using a separate tool.
Recommendations to others considering the product:
Inexpensive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Redacting resumes in PDF form. Easy to fill out forms as well as it recognizes what the form is asking.

Love the software
Love the software. Earlier I wrote that the software was difficult to navigate. I would like to rescind that statement. It was user error on my part. The software is very easy to navigate and I really, really like this product a lot.

I made a mistake and bought a year subscription instead of one month as I needed, I immediately emailed customer support and thought I would be waiting days for a reply if I was lucky, but to my surprise I received a response within 2 minutes. She offered to change my subscription and refund the rest of my money, I of course excepted and they changed it immediately! ***** ******** for your amazing customer service! And your forms, that have been time saving!

It really helps being Paper Less
It really helps being Paper Less. I don't need to travel to me nearest FedEx to Print job applications and drop them off at the actual location. I can just download the PDF and fill it out to send right back .
