What is a GIF?
GIF is a graphics format that was created by a programmer named Steve Wilhite in 1987. It is an acronym for graphics interchange format. The format is based on LZW compression and supports both lossless and lossy compression. GIF has been used on the internet since the late 80s. It has been the standard for lossless animation and image compression until recently.
Why GIF files are so large?
The main reason for GIF files being so large is that they are not compressed with a lossless algorithm, like PNG files.
GIF files are stored using a lossy compression algorithm that reduces the amount of information in each image. When an image is encoded as GIF, it is compressed with a compression algorithm that compares neighboring pixels and removes the pixels that are similar. This causes the image to lose information. This loss of information is referred to as “lossy” compression.
How to save a GIF File?
If we want to save the GIF animation, we can right click on it and select “Save Image As …”. Then we can watch the GIF whenever we want.
