reduce the redundancy of the image and to store or transmit data in an efficient form.

It seems like you're asking about image compression, which is a method to reduce the size of an image without degrading the quality of the image below an acceptable level. Here are the steps:

1. Choose the right image compression format: JPEG is a lossy compression method used for color images. GIF is a lossless compression method used for text and simple graphics. PNG is a lossless compression method used for high-quality graphics.

2. Use image compression software: There are many image compression tools available online. Some of them are free, while others require a subscription. Choose the one that suits your needs.

3. Adjust the compression settings: Most image compression tools allow you to adjust the compression settings. The higher the compression, the lower the image quality.

4. Compress the image: After adjusting the settings, compress the image. The software will reduce the size of the image by removing redundant data.

5. Save or transmit the compressed image: After compression, the image will take up less storage space and can be transmitted more quickly.

Remember, the goal of image compression is not just to reduce the size of the image, but also to maintain an acceptable level of image quality.
