Jpeg darkener

World's simplest jpg tool

This is a neat browser-based program that changes the brightness and darkens Joint Photographic Experts Group (JPG/JPEG) pictures. As soon as you paste your JPG/JPEG picture in the input area, the program will decrease its lightness and add darker tones to it in the output area. You can specify the darkness level of the JPG/JPEG in the options and select the region that will be dimmed. Created by mad scientists from team Browserling.

Jpeg darkener tool What is a jpeg darkener?
This online tool decreases the brightness in JPG, JPEG, and JPEG2000 format pictures. It makes a JPG dim, murky, and shadowy in the region you specify. For example, you can select any region and make the pixels in it 10%, 20%, or 30% darker. The darkness level is defined as a percentage of the original JPG. The initial value of 100% means the original amount of light and values below 100% mean less white light and more darkness. For example, the light level of 80% makes a picture 20% darker and the level of 50% makes a JPG twice as dark. You can decrease the amount of white light in any rectangular region that you can select in the live preview or specify it in the options using the parameters x, y, width, and height. To dim the entire JPG, just leave the rectangular region coordinates blank. Jpgabulous!

Darken the Entire JPEG
In this example, we darken a JPEG picture of a pond in mountainy meadows. We reduce the amount of light in JPEG's pixels and make the picture 25% darker over the entire 640×440 area. (Source: Pexels.)

Create an Area for the Title
In this example, we wanted to add the name to a JPG photo of our original brownie dessert so we created an area for the caption below it. To make the caption stand out, we created a high-contrast base background for the text by darkening a rectangular region at the bottom of the photo. The dimmed area is 575 by 150 pixels in size and it's 50% darker than the original JPG. (Source: Pexels.)

Dim a Half of a House
In this example, we make only half of a JPG/JPEG image darker by 20 percent. We set the starting position of the region in the options by entering the value 330px for the left-offset position, and we leave all other position and size parameters empty. As a result, the darkened area starts at 330 pixels and then expands to the right edge of the image, consuming the entire right side. (Source: Pexels.)
