It works, almost a must have thing. But not everything is perfect, there are some limited options. But you will never get it perfect because it is not an original document.

It was a huge help on a critically important document. It was a downloaded pdf that I had to annotate, but Acrobat Pro was unable to edit it because Livecycle Designer was required. PDFfiller allowed me to do it entirely online and then print out. the required hard copy It was a godsend!

I was filling out a stubby pencil application, and thought there has to be a better way. Now I'm happily dragging and dropping scanned files into PDF filler and like magic I have an automated workable document, it's fantastic.

There should not be an option for… There should not be an option for alteration on the PDF document. For example, when I tried to type my name, I made a mistake and I back space the mistake but I ended up deleting the line on the original PDF document. A program like this should not give me the option to do that. Other than that, I felt like PDF Filer got the job done for me.

It is a little difficult to figure out how to load an existing form with the saved name. I also had to Google how to enlarge the font. Most of the help directions are outdated, but I did finally figure it out after a lot of wasted time. I DO like the program in general and love being able to convert and save in a different format.

Kara helped me solve a mystery… Kara helped me to figure out a tricky issue that had to do with 'filling' a pdf. Kara figured out that it was a problem with my Chrome browser, so we switched browsers and it worked. Thanks.

pdfFiller.com gave me faith in online… pdfFiller.com gave me faith in online companies. I have no idea what I was trying to accomplish, but had signed up for a 30 day trial. I never used the program, just must have been sleep working. Anyhow, I was so surprised when I got the notification that I had just bought a year subscription. I was beating myself up and trying to figure out how I could be so unaware. I first tried to call. The phone was endlessly busy, I thought wow I just lost $122 (I paid in Canadian funds). Anyhow, I thought I may as well try sending an email. I could not believe it!!!! The response was almost immediate. Max, took care of everything. He issued a refund, and let me know he had cancelled any future subscription. I was in absolute shock. If I had a need for pdfFiller, in that moment, I would have signed up for years. THANK YOU for being accommodating and obviously trustworthy. Again, you have given me a bit of hope for humanity.
