Gif brightness changer

World's simplest gif tool

This online utility lets you change the brightness of a GIF animation. You can increase the brightness or decrease the brightness of a GIF by any amount. You can change the brightness of the entire frame or inside a specific rectangular region that you select. You can preview the brightness change before downloading the new GIF to your computer via a built-in GIF player. Created by GIF experts from team Browserling.

Gif brightness changer tool What is a gif brightness changer?
This browser-based program makes an animated (or static) GIF file lighter or darker. It increases or decreases the amount of white light present in the pixels. The brightness area can be either the entire GIF or a user-selected region on a frame. To lighten an animation, enter a brightness value greater than 100%. To darken the animation, enter a percentage value less than 100%. If you leave the brightness value at 100%, then the GIF won't change. For example, if you change the brightness to 110%, then the value of each color channel (RGB – red, green, blue) is multiplied by 1.10. This effectively makes a GIF 10% lighter. Similarly, if you set the brightness to 90%, then each RGB color channel is multiplied by 0.90 and the GIF becomes 10% darker. The two live animation boxes show GIFs before and after the brightness change. You can observe the brightness changes in multi-frame animations frame by frame or you can stop at the first frame to see how the brightness change affects one static frame. In the first animation box, you can control the brightness area by dragging the corners of the brightness rectangle and in the second animation box, you can see and download the final GIF with the changed brightness.

Make a GIF Brighter
In this example, we increase the brightness of an animation of a squirrel sitting on a fence. We select the entire GIF area of size 360 by 260 and set its brightness to 120%. This increases the brightness of the GIF by 20%. (Source: Pexels.)

Increase Brightness in a Specific Region
In this example, we brighten a rectangular region in the center of a rotating flower GIF. We select the flower starting at the position (35, 35) and increase the selection area to 175×230 pixels. We set the pixel brightness level inside of this region to 115% and the pixels outside of this region remain unchanged. (Source: Pexels.)

Make an Animation Darker
In this example, we make a GIF animation darker. To decrease the brightness, we enter a value less than 100% and set it to 85%. The dimmed area covers the entire width and height of GIF frames, which have the size of 380 by 214 pixels. (Source: Pexels.)
