What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The forms look much more professional when filled out in this manner, rather than a hand written form. Especially since typewriters are out of date. Thank You

I was shocked to learn AFTER I PAID that the "monthly" payment touted in 3 big choice boxes was ONLY and effective cost IF I paid an annual fee IN FULL. THAT WAS NOT CLEAR and I feel duped. However, I am extremely pleased with what you offer AND the ease of using your site. It is well worth the 29.99/month vs what I thought was 9.99. You really need to make that clear for your customers, though. Don't start a customer relationship with the customer feeling duped or tricked.

For a new customer who has only used this program for a short time, It's a bit confusing to find all the necessary information. I am learning, but it's taken some navigation, and I haven't used the help line, because I don't even know the right questions to ask.

What do you like best?
Very user friendly. Great app that also allows you to edit PDF documents while on-the-go.
What do you dislike?
It can sometimes freeze or crash, but rarely happens.
Recommendations to others considering the product:
Use this website & tool if you're on-the-go and work from your car or laptop frequently. It's very useful and easy to navigate.
What problems are you solving with the product? What benefits have you realized?
Working on the go without my computer nearby. Keeps my contracts neat & tidy by being able to cross things out and clearly type edits/changes.

So far seems great and 30 day trial is… So far seems great and 30 day trial is much better than competitions so I would recomend it for some basic PDF editing

PDF filler is great! it allows me to update an existing PDF document relatively easy and quick. Love that about PDF filler! I like how user-friendly it is. Definitely easy to use, even for a beginner! It also enhances the PDF file you are trying to update. I think every feature within PDF filler should be available to a paying member and not have these tiered membership structures.

I signed up for their services during a free trial, but ended up not needing them. When I realized I had been charged for their services, I immediately emailed them and they processed the refund right then. I offered to pay for the few days that I actually had since it was really my fault, but they refunded the full amount.
