What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I found the system complicated for someone not very experienced with computers. I still do not know how to find, on your system, the forms that I have completed. Where are they? How do I save them to my computer? I will keep working to find the answers.

The conversion from Pdf to word was the smoothest I've seen. There are very few errors. AMAZING! After reviewing the document I noticed that the conversion dropped the letter F. If there were two f's in a word the conversion dropped one of them.

What do you like best?
The ability to create a document, upload a document, search and find document files, edit, and then fax or email to anyone anywhere right from the convenience of your laptop anywhere in the world. All documents created are saved in your account for return access, and activities (fax, email and receipts for delivery) are also recorded and saved.
What do you dislike?
So far I have not discovered something I do not like. I have uploaded, created, searched for online documents to use, and both faxed and e-mailed documents without an issue.
What problems are you solving with the product? What benefits have you realized?
Can work and send from home, work, on the road. No need to hunt for a fax service / company; no need to leave where I am at to go fax a document; can work and send documents in the middle of the night right from home or while on the road; have been able to search and find online documents and upload into account for editing use; easy to share documents via PDFiller; you can send documents to anyone with an e-mail address - your recipient does not need to leave their laptop either!

Cancelled my subscription within the 30 Trial Period and was charged the following month. Had an online chat and they issued a refund with no questions asked. Good Business!

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.
