Best and complete tool to edit PDF documents. Editing PDF files is so simple and easy with PDF Filler like using a Doc editor. I use it everytime to edit dates and sign documents, just sign on my device with my finger so every signature is different. They could add a tool to increase the quality or resolution of scanned PDF files.

Though you have a great product, I no longer needed it.I had thought I had cancelled before the free trial was up, but, apparently, I had not. So, I asked for help to cancel and get a refund. It was done within a half an hour! Great Service!

USCG application form, cancellation. I used pdfFiller to downloand an complete an application. It was seamless, and worked as expected. More importantly, I realized I had little use for this app on a longterm basis.I cancelled (incompletely, it turns out) my trial subscription online.A month later I received notice that my 1 year subscription had been processed.Fortunately two of the technicians came to my assistance, on a Sunday, no less.They cancelled my subscription and confirmed the action with me.I was very impressed with their response, and commend the company for which they work!

Great PDF Filler! We needed and easy way to for patients to sign there name for Covid testing. Before we came across this they were signing with pen and paper and now they sign digitally on and case protected iPad that can be wiped down and sterilized. The iOS pdffiller app then digitally sends the completed PDF to a nurse. The whole process is seamless. PDFfiller is very easy to use. Some features that we love are: -Being able to convert a file into a PDF -Converting a PDF into a Fillable PDF -Creating PDF online. There is also a mobile application for Android and iOS that works great. Initially it was tough finding out where things were and where the files ended up when saved or converted over to be fillable. I think the menu could be simplified and reorganized.
