What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Excellent Product The product is offering me the ability to execute contracts/agreements on the fly no matter where I am. When traveling and a signature is required for contract execution, time is critical to completing the deal. PDFiller allows me to do that. PDFiller is simply the easiest and most useful product in its category. Simple to use and very user friendly. Honestly, it has done everything I have needed to for the past 3 years. If I had to say something, I would say maybe an easier way to save and send. But, that would be pushing it.

I was most grateful for the free… I was most grateful for the free service. I don't often need this type of software so was particularly pleased. Worked like a charm. Thank you

A good pdf editor, although there is still some work to do with the command consistency with the environment (windows keys, for instance while editing a document if we press home the screen goes to the header of the document).

What do you like best? I like how easy it is to upload documents and make the necessary changes to the documents that require modification. I have completed forms for students and uploaded signatures easily and have been able to successfully download documents as well. What do you dislike? I have noticed that sometimes when I upload a document that I previously edited using PDFFiller, it makes my signature super bold and not easily read. It changes the format automatically and I have to download a new document to upload and add a signature. It seems like once I utilize PDFfiller and download the document the format of the previous e-signature is no longer compatible. What problems is the product solving and how is that benefiting you? We had to provide e-signatures to international students on their I-20 documents and PDFfiller has been an integral part of that process. It has been very accommodating for me to upload documents and sign them electronically for students and then easily download them and email them back to the students.

Excellent Customer Service I contacted the customer service team of pdfFiller when I had a problem and it was dealt with straight away. I spoke to someone called Harmhon and they were really kind and understanding. They replied to me very quickly and the problem was resolved in less than a few minutes. Overall, I am very happy with the service and would definitely recommend to a friend.

I initially thought that PDFfiller was a free tool. Even though they asked me for my credit card information with a free 30 Day trial I forgot about the same. When I got an email a month later stating I had been charged for the whole year I logged in and chatted with Customer Service. They were so kind as to immediately understand, cancel my subscription, and agree to issue me a refund. At the time of writing this, I am still awaiting my refund as I just requested the cancellation today - but I must say that this gesture was amazing by PDFfiller and this review is the very least I can do. Thank you for brightening up 2020 a bit! Amazing business ethic and professional courtesy.

What do you like best? The link to fill option and the ability to manipulate pdfs. What do you dislike? Nothing yet. I plan to purchase again next year. What problems are you solving with the product? What benefits have you realized? Quicker document processing with the link to fill feature allowing to obtain digital signatures.

Honest business practices Like many other online products, they make it VERY easy to sign up, and not so easy to cancel. But once I found the correct place, they did allow me to cancel and refunded my money quickly. While the product did not fit my needs, the company appears to be legitimate and honest.
