The NVDA logo®

The NVDA logo® is a stylised blend of the letters NVDA in white on a square purple background. There is a vertical line on the left with a rounded hook to the right at the bottom as if starting to form the bottom corner of a “D”. Then from the top-left, a straight diagonal line comes down to the right. Next, a line curves in a semi-circle out to the right then back up to the top. The line finishes in a downward hook with a curved end. The vertical and diagonal lines make the first part of the letter N and also the letter A (without the crossbar). The diagonal and curved lines form a V, and the curve is the right part of the D.

“An issue is always looking for new work. Companies never hire us because they do not want to bear the cost of the screen reader. Making use of NVDA allows me to enter the labor market without requiring the company to bear the costs acquisition of a paid screen reader. NVDA allowed me to have many benefits.”

— Fernando, Brazil


“I have one client who can now manage her bank account and bills independently online, and this gives her such a sense of control over her life! I have others that can now send and receive emails instead of having someone else do it for them. NVDA allows everyone access to electronic information which is so very critical in today’s world!”
