Understanding Image Compression Fundamentals
Before we discuss the specifics of AVIF and WebP, it’s essential to grasp the basics of image compression. At its core, image compression is the process of reducing an image’s file size without significantly compromising its visual quality. This is achieved through various algorithms that identify and eliminate redundant data within the image file.
There are two main types of image compression:
- Lossy Compression: This method achieves higher compression ratios by discarding some image data that is considered less important for visual perception. While lossy compression can lead to smaller file sizes, it may also introduce some degradation in image quality, such as artifacts or blurring.
- Lossless Compression: preserves all the original image data, ensuring that the decompressed image is identical to the original. While lossless compression results in higher quality, it generally leads to larger file sizes compared to lossy compression.
