Remove the Background from a GIF – Online GIF Tools

This is a browser-based program that deletes the background color from all GIF frames. If your GIF is multi-frame (it's animated), then it loops over all frames and deletes the background from every frame. If your GIF has a single frame (it's static), then it deletes the background from just this one frame. When the background is deleted, you can download the transparent GIF right away. The area that will be removed from the GIF is selected by matching the specified color in pixels of the frames. For example, if you enter the color "yellow", the program will remove the yellow background from the animation. Similarly, if you enter a mathematical color value "#0000ff", the program will remove all blue pixels. If the background of your animation has various shades of the same color, you can remove them as well via the shade matching option. In this option, you can specify the percentage from 0% to 100%. For example, the percentage 0% means match just one color and 20% means match 20% of similar color tonality. To see exactly which pixels will be removed and which will remain, you can use the "Alpha Channel Preview" option. This option works only in the browser and illuminates the removal areas using black and white pixels. The "Animation Preview" option lets you see the input GIF with the original background and the output GIF with the removed background. In the options, you can also find a section about GIF frame delays, frame sizes, and frame counts. If you want to closely examine any one of the GIF frames, you can disable the animation and specify the frame number you're interested in. Gifabulous!
