图片优化须知的8个小技巧

1. 减少图片大小：通过缩小图片尺寸、降低图片质量或使用图像压缩器等方式减小图片文件大小。 2. 优化图片格式：选择最适合图片内容和用途的格式，如JPEG、PNG或GIF等。 3. 压缩图片：使用压缩工具减小图片文件大小，例如TinyPNG。 4. 避免使用过大的图片：尽量使用适合网页的大小图片，避免使用过大或过小的图片。 5. 避免使用无意义图片：只使用相关、有意义的图片，避免使用无意义或重复的图片。 6. 使用标准的命名规则：避免在图片名称中使用特殊字符或空格，使用描述性的文件名。 7. 压缩CSS和JavaScript文件：减少CSS和JavaScript文件的大小可以提高网页的加载速度。 8. 使用CDN加速：利用内容分发网络（CDN）加速图片的加载速度，提高网站的性能。
