Below are some important Steps.
- Resize Images Before Uploading: Before uploading images to your website, resize them to match the required display dimensions. This practice reduces the need for browser resizing, resulting in faster load times.
As a general rule. Aim to keep images below 1920px in width for full-width displays and approximately 1200-900px for product and content images. - Compress Images Without Compromising Quality: Leverage image compression tools or plugins to reduce file size while maintaining visual quality.
As a general rule. Aim for a file size around or below 100kb by utilizing compression settings between 70-90%. - Choose the Right File Format: Select file formats that balance image quality with performance. Use JPEG for photos and complex images, and PNG or SVG for graphics, logos, or images requiring transparency. Avoid uncompressed formats like BMP or TIFF, which are large and slow to load.
At the time of writing, accepted formats include: .png, .jpg/.jpeg, .gif, .webp (served automatically in supported browsers), .heic, .heif, and .svg.
As a general rule, use .jpeg/.jpg, you can also use WEbP and AVIF formats for even more compression, although a .jpg file in the appropriate dimensions that is compressed, should suffice for most use cases. - Implement Lazy Loading: Employ lazy loading to defer the loading of offscreen images until they are required, thereby reducing initial page load times. WordPress plugins such as WP Rocket and Lazy Load by WP Rocket offer convenient solutions for implementing lazy loading, enhancing overall performance and user experience.
As a general rule, you won’t have to worry about Lazy Loading when uploading images as WordPress plugins should handle this on the fly for you. - Don’t Forget your ALT Tag: While not directly affecting site speed, ALT tags are crucial for accessibility. They provide descriptive text for images, making content accessible to visually impaired users. This improves user experience and inclusivity. Additionally, ALT tags benefit SEO by providing valuable image content information, potentially improving search visibility.
As a general rule, simply describe what you see in the image. For example the image below’s ALT Tag is ” An Image of a computer screen showing image editing software, with a coffee cup on a desk. Used for Optimize Images for Web Article.“
