👉 The thumbnail fluid is a technique used in image compression, particularly in formats like JPEG and WebP, to enhance the visual quality of thumbnails while maintaining a balance between file size and image clarity. It works by analyzing the content of the thumbnail region and applying adaptive filtering to reduce noise and smooth out color transitions. This process results in smoother, more visually appealing thumbnails that are easier on the eyes and still retain sufficient detail for quick visual inspection. By intelligently adjusting the compression based on the local image content, thumbnail fluid ensures that the final image looks sharp and engaging without unnecessarily inflating the file size.
