I've tried other programs to convert pdf files and it didn't work. At least you were able to convert from pdf to a document I needed to type and enter information on before submission. I would like to save my resume' in a docx. file without loosing the format. My resume is already created but I would like to make changes on it when I get a new job. Please help!!!

It was a great experience because you can do many things with the opportunity to complete them in just a few easy steps. This is a very useful and well-organized website because it offers a lot to keep things at a minimum.

Makes creating and filling out forms a breeze!
Overall, if you need to have PDF forms in your life, you couldn't ask for a better solution than this. I'm just waiting for the day when it the basic version isn't free anymore--let's hope it never comes!
We live in the twenty-first century. So few things rankle me more than seeing someone's sent me a Word document and pretended it's a form. The same is true for people who send me PDFs and expect me to print and fill them out by hand. PDFfiller is the solution to all these problems and more. It makes the sending and receiving of forms so easy that even a kid could do it.
I really have no complaints about PDFfiller. It does what it needs to do quickly and easily, and it didn't take me long to learn how to use it. Even things that once seemed formidable to me (for instance, the dreaded splitting and combining of PDFs) is easy with PDFfiller.

Great Program to help buyer's get their electronically signed documents
It makes it much easier for the buyer to get documents that can be electronically signed.
Quality of the documents that get sent to my buyer's is fantastic. The look of the documents are professional quality
Ease of use. It is hard to remember how to set up the file to get to the buyer quickly. I always have to try it 2 different times to get it right.

Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed the 1year subscription. Advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. They communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month and cancelled my future subscription. I would happily use this again. Thank you.

Actually, I just came across this with a standard google search. I was using Adobe Illustrator and it was overkill and took ages to load every time I just wanted to update a PDF file. This has been awesome and so easy and quick to use! The 'Signature' option was a bonus as well!
