Image compression techniques can be broadly classified into two categories: lossless and lossy compression. Lossless compression methods reduce the file size without sacrificing any image data, ensuring an exact representation of the original image. On the other hand, lossy compression achieves higher levels of compression by discarding certain non-essential image data, resulting in a slight loss of quality. The choice between lossless and lossy compression depends on the specific requirements of the application or use case.
Compressing images to a mere 15 KB poses a unique challenge due to the extreme size limitation. However, by employing the appropriate techniques, it is possible to strike a balance between file size and visual quality. Selecting the right image format, resizing the image, utilizing compression techniques, removing unnecessary data and metadata, and leveraging specialized compression tools are all crucial steps in achieving the desired result. While maintaining image quality may be challenging within such constraints, careful consideration and experimentation can lead to successful compression without compromising the essence of the visual content.
