This online utility lets you remove the chroma-key color from static or animated GIFs. You can turn green screens, blue screens, or other keyed backgrounds into transparent areas, and adjust the color tolerance percentage to expand the range of removed shades. You can also preview the transparency effect across all frames, and loop or pause the GIF animation. Created by GIF experts from team Browserling.

This is a browser-based program that removes a chroma key from any GIF, turning a selected color range (usually green or blue) into transparent areas. This allows you to isolate characters, objects, or elements from their background, making it easy to create overlays, stickers, or composite animations. Chroma key, or color key, is a technique that makes a single color transparent, letting you combine different layers of images or videos. For GIFs, this results in a transparent background, ideal for use in social media or video projects. In the tool's options, you can adjust both the color identification and the removal of the chroma key. The "Chroma Key Color" option lets you select the exact hue for removal (e.g., green, blue, or even white). The "Color-key Tolerance" (range 0% to 100%) determines the tool's sensitivity to shades surrounding the chosen chroma key color. The higher the percentage, the more similar shades will be included in the transparency zone. The "Alpha Mask Preview" checkbox allows you to view the alpha channel (transparency channel) as a binary black-and-white mask. This is a standard mask where white areas show the opaque (visible) parts of the GIF, and black areas show the keyed-out (transparent) regions. Animation playback options allow you to play multi-frame GIFs and observe the transparency effect on all frames, as well as stop the animation on a selected frame for detailed analysis of the chroma keying results.

In this example, we load a popular reaction-style GIF featuring a man smiling in sunglasses. The original animation was intentionally created on a green-screen background so it could later be turned transparent and used as an animated sticker. We apply the chroma-key color set to #2AD51C and use a 40% tolerance to fully remove the different shades of green behind the subject. (Source: Pexels.)
This example demonstrates a GIF sprite of Ken Masters from the Street Fighter series, created with a blue chroma key background. Many classic and retro game sprites were produced this way because older graphic formats did not support real transparency, so the blue or green screen served as a fake transparency placeholder. We select the chroma key color rgb(0, 26, 254) with a 30% tolerance and remove the background while preserving every pixel art detail. (Source: Capcom.)
In this example, we upload a static GIF featuring a new collection handbag. The photo was originally taken against a green chroma key background so it could be reused across ads, banners, and other promotional visuals. We remove the green chroma key color and produce a transparent GIF that can be placed onto any layout, surface, or scene. (Source: Pexels.)
