Understanding Image Compression: Lossy vs. Lossless
When it comes to image compression, there are two primary methods: lossy and lossless. It’s crucial to understand the differences between these two approaches to make informed decisions about your image compression strategy.
Lossy Compression
Lossy compression reduces the file size by discarding some of the image data. This method is commonly used for web images, as it provides a significant reduction in file size without drastically affecting the visual quality. However, since lossy compression removes data, it’s not ideal for images that require high-quality printing or editing.
Lossless Compression
Lossless compression, on the other hand, reduces the file size without sacrificing any image data. This method is perfect for images that require high-quality printing or editing, as the original data remains intact. However, lossless compression typically results in larger file sizes compared to lossy compression.
