What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The only reason I did not give it 5 stars is because it does not have an option to undo things if you make an error. If you make an error you have to restart the whole thing. Otherwise, its a great program to have!!!

Had to fill in a long medical form. PDFfiller makes it easy and a lot neater than my handwriting. Also, I have to fill this out once a year for the same doctor and it will save me time not having to fill it out from scratch. All I will need to do is verify any information to make sure it hasn't changed and place a new date on it and send it.

It takes a minute to get use to but I think I'm getting it. Trying to use to send files to the government. I was trying to figure out how to just save a pdf filled out.... there are so many pop up windows.

I think the learning curve is a little steep. Also, at times the app seems a little counter-intuitive. It's not always easy to find forms you have worked on previously.

Locating forms is a little… Locating forms is a little slow/complicated. Also would like to be able to save information that will be repeated on other fillable forms.

How To Black Out Text in PDF Files Open our online PDF editor. Drag and drop a PDF into the toolbox. Click on the square symbol and select ”Rectangle.” Set the color to black and resize it to cover text. Done!
Tips to Black out Text in PDF without Redacting Use the right color and opacity: When blacking out text, choose a dark color that is not easily visible through the fill. Adjust the opacity to your preference to ensure that the blacked-out text is not easily readable.
To do this, navigate to Tools and select Redact > Redact Text & Images > Find Text & Redact. This makes it easy to identify and then black out that content throughout the document. You can also specify general patterns, such as phone, Social Security, or credit card numbers.
Right-click (Windows) or control-click (Mac OS) the comment or edit and select Properties. c. Under General delete the author name. Type in “Reviewer” or “Anonymous” or leave the author field blank.
