What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I was a little confused when I first began using the app, but did an online chat with their agent who walked me through what I needed to know. Therefore; I would recommend this subscription to any Commercial Insurance Agent who issues multiple Acord forms.

Very professional, highly recommended.
I needed to create some fillable PDFs for a course I'm running and PDFfiller allowed me to do that with ease. I needed a bit of guidance on how to do it from their person in the chat box (who was very helpful and efficient) and, once they showed me what to do (it was easy), the software was great and pretty intuitive and allowed me to create fillable boxes neatly and easily - it gives you guidelines so you can line them up with each other. It's a pity they don't do a "one-off" fee of $5 or something, rather than a subscription because it's not something I need regularly, so I'd have been happy to just pay a little something toward using it, rather than signing up for the 30 day free trial. Highly recommended. Very professional. Lisa Cherry Beaumont of LisaCherryBeaumont.com

I use the website to do my W-2s and it was so easy. Then When I forgot to canceled my subscription because I am to small of a company to use them all the time they were so helpful and easy to work with. They gave me a full refund. There customer service is great and it is an such an easy platform to get things done with.

Life made easy
If you fill a lot of forms, it is worth it. Otherwise you might not want to pay for the subscription for just one form.
It makes editing and filling out forms so quick. The tools are great and the UI is easy to use and clean to look at.
Once you fill the form, you have to pay or else you cannot save or print. This is not made clear from the start.

We no longer had use for product as we are a small Not for Profit Organisation and they canceled our subscription that was automatically renewed and refunded the $'a that was charged. This happened without any issues and thanks to pdFiller for their understanding

Worth the money
I've been subscribing to this service for several years! I love it! It's nice to be able to start on my laptop or phone and pick up where I left off on the other device. The download notification feature is nice because it ensures the person got your email and actually downloaded the file. Will maintain my subscription for the immediate future.

Having better results with the site It is a lifesaver as far as my clients being able to sign consents on the screen and get them back to me. So far, the recipients of my docs have been able to follow the instructions and sign the docs without difficulty
2020-04-29
Completed what I needed done
Completed what I needed done. The reason for 4 stars is because you force people to sign up for a monthly subscription versus just charging for the one time use of the feature.

Reduce the number of colors To reduce the file size, just choose a palette of a few colors and stick to them. You'll get the best results if you only use 2-3 colors. Remember, bright and intense shades of color take up more space, so try using a few neutral colors and maybe a bright one.
