It's Great!! I use it all the time. My son recently graduated and he is on his way to college. I have used PDF filler for almost all his enrolment forms and rental agreement. It has been a great help comunicating with his college. Thank you.

When I started searching for a PDF to Word doc. a few days back, I downloaded 4 different trials and hated all of them!! They were not user friendly like this one is!! To anyone reading this, DO NOT waste your time researching other apps, you will not find anything better then this one! I would absolutely recommend PDFfiller to anyone who is reading this!!... and so will you.

I love the site, I don't like all of the pop ups though! I constantly have to click out of the pop ups when opening a new form. That is my only complaint! But, all in all, I love this site and it helps me be more efficient.

Minimal experience. Does take the time out of huge forms to fill out - even for my kids' school. $20 a month is a lot for the convenience. I will likely cancel after my 1 month.

PDFfiller is very easy to use and the auto-save feature works reliably. One thing that I didn't like was that I had to sign up for a plan to be able to save my pdf. Had I not chosen to sign up, I believe my work would have not been saved. What compelled me to sign up was that I didn't want to lose the work that I was doing. Overall, I think PDFfiller is a great tool and worth the money; however, some users may not like the mandatory payment in order to see their documents again.

pdfFiller provides what it offers-you can add text, and signs (such as the check sign where applicable on boxes) and there are a lot of other features to share the document, from email to links etc. Best part is that it doesn't alter the original PDF format.

How do I edit a signed PDF document?
If a PDF is signed using a digital ID or certificate, it's locked to prevent changes to the document.
If you got a signed PDF, you can request the signer to remove the signature and share the PDF or send an unsigned copy of the PDF.
If you're the only one signer, you can remove your signature and work on the document.
How do I unlock a PDF after signing?
Click the 'Lock' icon in the upper-left corner of the page. Click the link labeled: Permission Details. In the “Security Method' drop down, select: No Security. Enter your unlock password and click the OK button three times.
Why can't I edit my PDF file?
There are several reasons why you can't edit a PDF document. You have a scanned document in this case, you need to perform OCR to convert it into an editable format. Your PDF app doesn't support editing for example, not every PDF reader allows you to change a text in a PDF file.
