I experienced quite a steep learning curve. Meaning, the directions I would have found easier to follow would be in steps...step 1, then step two, etc. In other words, the program was really user friendly to first time user. Also, I thought I signed on for a5.95 one month contract that I could cancel at any time. Why am I being charge19.95 Please answer this question. Thank you

Love this program! It allows you to download any document and make it your own. No more handwriting which leaves room for errors. The only part that confuses me is the saving of a document to be used over and over... haven't quite figured that out yet.

The program requires no OCR software which in my experience creates lots of problems for most "Form Filler" software I have tried to use in the past.

I love it! my only gripe is not being able to send emails with pdf's as normal attachments. I have to send a lot of PDF's to insurance companies and they complain that their systems cannot open the PDF's as sent from pdffiller so I have to take the time to download them from pdffiller, upload them to my CRM, and then attach them in emails. It would be great to be able to save that time. But other than that I am very impressed with the service.

It is very user friendly. I do not like that you have to use the eraser to delete text but otherwise it is way better than other programs I tried. I am also having problems opening pdf filler links on my business account because it goes to my personal account every time because it's on the same computer. I will call customer to fix the problem. Otherwise we are very happy with it!

I am very impressed with PDF filler and its features. i am not the most computer literate person and i do have a bit of trouble navigating around the program so a demo of some kind would help me a lot if there is one that i can watch. I guess its just a case of playing around with it but there's probably loads of easy shortcuts that i could use if i knew about them .

Instructions and Help about Concatenate Header Work For Free

Concatenate Header Work: make editing documents online simple

The PDF is one of the most common document format for various reasons. It's accessible from any device, so you can share files between desktops and phones with different screens and settings. You can open it on any computer or phone running any OS — it'll appear exactly the same.

The next primary reason is data safety: PDF files are easy to encrypt, so they're risk-free for sharing data from person to person. PDF files are not only password-protected, but analytics provided by an editing service, which allows document owners to identify those who’ve accessed their documents and track potential breaches in security.

pdfFiller is an online editor that allows to create, edit, sign, and share PDF files directly from your internet browser tab. Convert an MS Word file or a Google Sheet, start editing it and create fillable fields to make a document singable. Forward it to others by fax, email or via sharing link, and get a notification when someone opens and completes it.

Use editing features to type in text, annotate and highlight. Add fillable fields and send documents to sign. Change a template’s page order. Add and edit visual content. Collaborate with others to complete the fields and request an attachment if needed. Once a document is completed, download it to your device or save it to cloud.

Complete any document with pdfFiller in four steps:

01
Browse for your document from the pdfFiller's uploader.
02
Proceed to editing features by clicking the Tools tab. Now you can change the document's content.
03
Add input fields if you need any: pdfFiller supports text, checkboxes, radio buttons, dropdown lists etc.
04
When finished editing, click the 'Done' button and email, print or save your document.

Get documents done
from anywhere
