IT HAS SOME TREAKY THINGS AND AT SOME POINT IF IT IS NOT PRINTED OR SAVE BEFORE HAND, YOU HAVE TO REPEAT THE WORK ALREADY DONE. IN THIS CASE, HAS BEEN A LITTLE UNPLEASANT SITUATION AND WASTE OF TIME, IT SHOULD HAVE SOME AUTOMATIC SAVING, AS IT OCCURS IN WORD.

It's not as intuitive as I hoped to use the mobile apps, and it seems there are many steps to doing the main process which led me to purchase PSF filler--uploading and emailing HIPAA related documents that I've photographed. I'm sure there'll be a learning curve, however, so I am still hopeful. With two helpful and timely chat guidance, I was able to resolve my problems with scanning and uploading photographed documents quickly. I still wish the mobile app allowed me to rename the document so that I wouldn't have to fiddle with it later in the browser app, but am happy with many other features at this point.

I have been hand writing my proposals and invoices for my landscape business for 30 years. It was time for me to create a neater and more professional means of presenting proposals to clients. PDFfiller meets all of my needs and is quite simple to use.

Very easy to use That I could fill it in immediately and be able to upload it and save it somewhere else. Also that the formatting remained the same That I had to save it twice in order to get what I had wrote. I also hate that the text box does not stay within the area you type in.

PDFfiller is cloud based, so that wherever I am in the country, I have access to my files , and access to the application.

It works well in that you can fill out the form, but... It works well in that you can fill out the form, but it would be great if you could move the text box once you've started. I was unable to do that and had to start over in some cases because alignment was off.

pdfFiller, a better alternative to your PDF editing solution

From all PDF editing tools available on the market, there are not many providing all essential features in one product. It should seamlessly transform various file types without affecting the original formatting. The majority of the tools are providing this functionality one way or another, but limited or as a separate product.

For a daily use, you'll need a cloud-based solution that will guide you all the way from a document creation to its signing. Nowadays, most users won't use a program or website to just change some text in their document — they need a multi-purpose tool to make a workflow fast and efficient.

pdfFiller is browser-based, and it means that you can access it from anywhere you have a reliable connection to the internet. In addition, it’s cloud-based, so your documents are safely stored in the cloud and can be easily accessed by you, your teammates, or anyone who has a permission, at the same time.

A powerful solution for managing your PDFs offers:

01
Create professional documents yourself; business, tax, legal, etc.
02
Go to the form library for over 25 million ready-to-use fillable documents
03
Get a mobile application for your iOS or Android device to get paperwork done on the go
