By Daniel Walker
Dark pictures are a common problem in today's online world. Whether it's a downloaded picture from a web page, a screenshot, or a received image, the details in pictures can often become lost because of a lack of brightness. Many people would rather not install software just to edit one image. This is where an increased image brightness extension becomes useful.
Extensions for web browsers allow users to edit image brightness in seconds. While still in the web browser, users can edit brightness, exposure, and other contrast settings. In this article, we learn why extensions can be a good option, explore some free image brightness extensions, and also explore a professional option for those who value image quality.
Why Browser Extensions Rule for Image Brightness
Users often do not want to install full photo-editing software just to make minor changes, like brightening dark images. This is where an increased image brightness extension becomes a practical choice. Shortcut browser extensions are designed for convenience, giving users tools to achieve results with very little effort.
Here are some reasons why browser extensions are the best choice for adjusting image brightness:
