What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Only used twice but each time I was pleased with the features and ease of use. The only negative is that it is difficult to save files. I had to use a two step process of saving to PDF Filler then copying to my local drive.

So far I absolutely love it. I figured out that I can have my clients sign things electronically through this and I swear that alone makes it worth its weight in gold!

Much better than last year. But the pages slide badly -- need one page at a time to finish rather than slipping from page to page as I try to work on just one.

Customer service is A1! Wow! Customer service is A1!I needed to fill out some forms for an outfit, a one-time thing, and signed up for the trial month.Later in the month I tried to cancel the trial period before my credit card was charged the $20, but I forgot which email account I'd used to sign up, so I was unable to log in to my PDFfiller account.Today, when I received the email saying my credit card was charged the $20, I was able to contact PDFfiller since I now knew which account I'd used. I contacted them via "Contact Support" in their website and explained my situation. OMG! When it said I should receive an email in 20 minutes or less, I was thinking, "Yeah, right!" but it was literally only minutes before I received an email saying they would be glad to cancel the subscription and refund my money.If I ever need this type of service on a more regular basis, I will definitely be signing up with this company!

Happy with PDFfiller! PDFfiller makes the documents that individuals within my company need to use frequently, more readily available, an improved option to frequently having to make copies before working with clients. I really appreciate the functionality and ease of use for the product. The fact that it is possible to create a fillable PDF, to be used by multiple people or times. Uploading documents is extremely easy and the layout on the website makes all features easy to find. My absolute favorite thing is that you can sign things by singing from your phone, or saving a signature that you already have saved. My only frustration is that if you download a fillable PDF, even when saving it will a different name, you can't print it with the content. I have found that I have to import the document and then print directly from the website, yet when uploaded the document makes the typed font smaller. Another tricky thing is that if you want to create a fillable PDF you must meticulously go through the document to check and highlight anything that you want to be able to fill information.

My experience with PdfFiller was great My experience with PdfFiller was great. I use PdfFiller as a cloud storage for backup files, in addition I can multitask by retrieving signed documents and save them in my signed doc. file for later.
