pdfFiller scores top ratings on review platforms
I've been using Adobe for all my PSF editing needs, but this program is so much easier and faster, I can't believe I wasted my time and $ on Adobe for way too long! so glad I found this program!
It is easy to use and there is no watermark which is really great when it is something that I am going to have to turn in professionally. They do a great job of making the pdf to write in
It was a wonderful experience. All the reps were competent, patient and more than willing to offer their assistance for any problem or any issue that I was confronting. And I am happy with the results
What do you like best?
I like how intuitive PDFfiller works compared to using a typical graphic design application to fill out PDF forms. PDFfiller does a good job at understanding how to format common documents and makes it easy for me to download files after filling them out. I think that the pricing for PDFfiller is very reasonable and the website is designed very professionally.
What do you dislike?
I have been able to use PDFfiller very smoothly in the time that I've used it, but it's not always perfect when it comes to formatting certain documents. I think they are improving all the time though.
Recommendations to others considering the product:

What problems are you solving with the product? What benefits have you realized?
We work with lots of digital documents, and since it can take a long time to fill them out through printing, writing and scanning, PDFfiller really helps to streamline the document filling and signing process. Everyone on our team that uses PDFfiller was able to start using it without problems pretty quickly.

Very helpful in my law practice.
Ease of filling out a variety of documents.
Easy to use. I like being able to switch from the wizard option to the self fill-out option. It is usable with all the legal forms I fill out.
I do not like how I cannot change font size when using the wizard to fill out form. Sometimes I don't have enough room in the space to type what I need. I also don't like how you lose what you have filled in if you switch from the wizard half-way through.
literally this app has changed my life and has made it so much easier and convienant for me always being on the go and now i dont really need to be on the go its just right here everything in one
It's user friendly and I'm figuring it out as I go... just a bit of support with downloading to my google drive and figuring out why/when to use the link would be great.
This is a great service
This is a great service. Easy to use. Easy to upload, edit and share documents you need others to review. Also extremely easy to fax and there's even a service to mail the document within the U.S. from your computer from anywhere in the world. Highly recommend it.
Student charged 115€ despite cancelling…
Student charged 115€ despite cancelling free trial – very disappointed
I am extremely disappointed with my experience on pdffiller. I had signed up for the free trial, made sure to cancel it before the end, and yet I was still charged €115.20 for a full annual subscription without my consent.
I am a student, and this unexpected charge has pushed my bank account into overdraft, causing me financial stress. I never agreed to any paid subscription, and when I log into my account, it still shows as “free”, proving that I had cancelled on time.
After checking Trustpilot, I realized that many other customers are facing the exact same issue — this seems to be a recurring problem.
I have contacted customer support and sincerely hope they will resolve this quickly and refund me. But this situation is really unfair and unacceptable.
