To set the brightness, use the brightness property and for contrast, use the contrast property.
Example
You can try to run the following code to use image filters with JavaScript −
<!DOCTYPE html> <html> <body> <p>Click below to change the brightness and contrast of the image.</p> <button onclick="display()">Edit Image</button><br><br> <img id="myID" src="https://www.tutorialspoint.com/videotutorials/images/tutorial_library_home.jpg" alt="Tutorials Library" width="320" height="320"> <script> function display() { document.getElementById("myID").style.filter = "brightness(50%)"; document.getElementById("myID").style.filter = "contrast(50%)"; } </script> </body> </html>
