The internet giant promised the rewards to all who were able to find security bugs in the browser.
"One of Google’s core security principles is to engage the community, to better protect our users and build relationships with security researchers. We had this principle in mind as we launched our Chromium and Google Web Vulnerability Reward Programs," wrote Chris Evans and Adam Mein on the Google blog.
They said that the rewards have resulted in over 2 000 bugs being repaired to ensure that the software is safer.
"The collective creativity of the wider security community has surpassed all expectations, and their expertise has helped make Chrome even safer for hundreds of millions of users around the world."
The Chrome browser has rapidly become of the most popular programs for consuming online content.
It jumped from a 22.4% market share in 2010 to around 52.8% in 2013, according to tracker, w3schools.com.
Google wanted to disrupt the browser when the company decided to build Chrome, and security, simplicity and performance were the three main criteria for the browser.
"The main purpose of this browser was to spark innovation into the whole browser industry," Lars Bak, one of the key men behind Google Chrome told News24 from Denmark on the three year anniversary of the browser.
Google also announced that the rewards would be increased, especially for bugs discovered that might have an impact on user safety.
"In a nutshell, bugs previously rewarded at the $1 000 level will now be considered for reward at up to $5 000."
