What Is Image Compression?
Image compression reduces the file size of images without noticeably affecting quality. It’s crucial for web performance, bandwidth savings, and mobile-friendliness. There are two main types: lossless (keeps all image data) and lossy (removes some data to reduce size).
Why Compress Images for the Web?
Large, uncompressed images slow down your site and hurt SEO. Google prioritizes fast-loading pages, especially on mobile. Compressed images mean faster sites, lower bounce rates, and higher engagement.
