What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Pretty easy to use...so far. The only thing that concerns me was I didn't realize I had to pay for this until I had finished filling out a complex form. How did i miss that information at the beginning?

I love it! my only gripe is not being able to send emails with pdf's as normal attachments. I have to send a lot of PDF's to insurance companies and they complain that their systems cannot open the PDF's as sent from pdffiller so I have to take the time to download them from pdffiller, upload them to my CRM, and then attach them in emails. It would be great to be able to save that time. But other than that I am very impressed with the service.

What do you like best?
I really like that PDFfiller is a very user friendly and employs a lot of the same standard editing tools commonly found in simple office software like Microsoft Word. It's a great step up from the standard Acrobat Reader and also has an easier learning curve than some of the more advanced Adobe PDF products. Being able to sign documents electronically is another strong feature.
What do you dislike?
When I edit a document that has more than one page, I am unable to perform a copy and paste across multiple pages, which is a bit annoying when trying to standardize items across one document. Saving documents is also very easy. We can save the document to any one of my computer folders or a cloud storage account.
Recommendations to others considering the product:
I think that PDFfiller is a very effective and easy-to-use PDF editor and converter. For the price and functionality, it's definitely worth checking out, in my opinion.
What problems are you solving with the product? What benefits have you realized?
Since we often deal with many types of text documents, especially Word documents, PDFfiller has really helped to enable conversions of Word documents to PDF, which are more ideal for certain things like printing. We can also convert PDF files to Word, which greatly reduces our need to perform time-consuming typing. In general, PDFfiller has been a great tool for working with PDF files with its intuitive interface and clear functionality.

Needed an online PDF editor for contracts, works better than expected! I can sign and edit PDF files anytime, anywhere. The availability of it from any device, anywhere. All the platforms are great both the web and local apps. Sometimes it's laggy because it runs online but I suppose that's the tradeoff of having it available everywhere.

I used it to copy signatures onto other documents to make signing them easier. I was pleasantly surprised by the quality of the signatures and the ability to manually clean them up easily. I appreciate this service and would recommend it to others.

I used it for my rental application and lease. The app at times was very slow to open. that's why I rated it a 4/5. Other then that it was easy to use.
