What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It's somewhat costly, but it works. I have no idea whether it's worth it. I needed to get something done, and it was easy to find, so it was worth it to me. I certainly was glad there was a half price sale.

I lost you.... I found you then I tried to get a refund unable to figure out your site.... I tried for months you can see it was never used, CHASE tried to reach you...long story you had popped up I never noticed the name of this when I crashed that was it... I have all of the old emails off a hard drive on a back up device... I might re sign but 30 days is not worth losing 72.00 I dont use this much most of my forms are already loaded not sure yet I have become further disabled trying to recover back then your chat did not work nothing....

Maybe I haven't found it, but it would help if there was a way to stop the fillable areas from snapping to each other. I had to figure out work-arounds for a lot of them.

Best customer service and software! It's the easiest program for faxing from your computer, converting docs, signing forms, making forms editable. I love it. Above all, they have the best customer service I have ever received. Especially for a product that speaks well for itself. Anna, with tech support, was quick, efficient, kind, very knowledgeable and addressed my issue right away. It has been a long time since I can say that. Not listening to me and my problem has been my experience lately with other tech support from other companies. They want to give cookie cutter responses that don't address anything I was asking. Anna, you made my dreading to chat to support a rewarding experience. Thank you so much! I know I will not dread the next time I need support with PDFfiller.

My name is Jonathan from Africa My name is Jonathan from Africa, I needed a form via PDFfiller but was unable to use the service and was billed while on 30 days trial. That got me upset but after contacting Shennon online support, I was assisted, and in less than 10 minutes, it was resolved. Shennon exceeded my expectation. Satisfied. Therefore I commend Shennon for a great and wow customer service. Because of this singular act, I will recommend your company to friends.Thank you

PDFfiller is great, but other free options are just as good I love the ease of use. I have to fill out a ton of PDF files and it really made my life easier. I don't like that it costs money. I'd rather deal with ads then pay. There are plenty of other options out there that are free and just as easy to use.

What do you like best? I like how easy it is to load my documents into pdfFiller & the multiple option for export when I'm finished. What do you dislike? Not a fan of the constant email verification especially since I've been using it for 3 years now & this is something just started in 2020 (it seems) What problems are you solving with the product? What benefits have you realized? I don't have a fax so its much easier for me to receive email documents, sign them with the signature feature in pdfFiller, and send directly to the recipient from the program. I get a notification, too, telling me my document has been downloaded. This has helped me a lot lately.
