Introduction: Why Image Format Matters
Images power the web. From social media posts to websites, e-commerce
stores, and design projects, the format you choose can dramatically impact quality, speed, and compatibility.
Pick the wrong format, and your website loads slowly, or your image looks blurry. Pick the right one, and you balance quality + performance.
