1. Choose the Right File Formate

Before you begin optimizing your images, it's crucial to select the most suitable file format. There are various file types available, each with its own characteristics and considerations. Understanding the differences between them will help you make informed decisions for your image optimization needs.

‍

Among the commonly used file formats are PNG, JPEG, and GIF. PNG offers higher image quality but comes with a larger file size. It was designed as a lossless format, although it can also support lossy compression.

‍

JPEG, on the other hand, uses a combination of lossy and lossless optimization, allowing you to adjust the quality level to find a balance between image quality and file size. GIF, limited to 256 colors, is primarily used for animated images and employs lossless compression.

‍

While there are other file formats available, such as JPEG XR and WebP, their support may vary across different browsers. For most website owners, JPEG, PNG, and GIF are the key formats to consider.

‍

When it comes to image optimization, compression plays a crucial role in finding the right balance between quality and file size. Understanding the impact of different compression levels is important to ensure optimal results for your images.

‍

For instance, applying very low compression results in the highest quality but larger file sizes, as seen in the first example image. Conversely, high compression yields significantly smaller file sizes but compromises the image quality, as shown in the second example.

‍

Various types and levels of image compression are available, and the settings may vary depending on the compression tool you use. Popular image editing software like Adobe Photoshop, ON1 Photo, GIMP, and Affinity Photo provides built-in compression features. Additionally, web-based tools like Shrink.Media and JPEGmini offer convenient options for image compression.

‍

‍

Finding a balance between compression rate (quality) and file size is important. This ensures that your images maintain acceptable quality while keeping file sizes optimized. For example, the third image in our example strikes a medium compression rate, resulting in good quality with a file size of 151 KB, which is acceptable for a high-resolution photo.

‍

You can utilize WordPress plugins such as Optimole and EWWW Image Optimizer to streamline the compression process. These plugins automatically compress images upon upload, making them convenient for beginners and larger organisations.

‍

By understanding and implementing appropriate compression techniques, you can effectively reduce the file sizes of your images while maintaining satisfactory visual quality, enhancing your website's performance.

‍

3. Lossy vs. Lossless Compression:

When optimizing your images, it's essential to understand the difference between two compression techniques: lossy and lossless. Each method offers distinct advantages and considerations.

‍

Lossy compression involves selectively discarding some data from the image, resulting in a reduction in file size. However, this process also leads to a degradation in image quality. Tools like Adobe Photoshop and Affinity Photo allow you to adjust the quality settings for lossy compression. It's important to balance file size reduction and maintaining an acceptable level of image quality.

‍

On the other hand, lossless compression compresses the image data without compromising quality. The compressed image needs to be uncompressed before rendering. Desktop tools like Photoshop, FileOptimizer, and ImageOptim offer lossless compression options.

‍

To determine the optimal compression technique, it's recommended to experiment with different settings for each image or format. Many image editors provide the option to save images for the web, allowing you to make quality adjustments for optimal compression. It's important to find the right balance that reduces file size while preserving image quality to avoid compromising the visual appeal of the images.

5. Resizing Images to Scale:

When optimizing images for web and performance, resizing them appropriately is important. With the introduction of responsive images in WordPress 4.4, uploading images at an exact scale has become less crucial, as WordPress now generates multiple sizes of each uploaded image.

‍

By utilizing the srcset attribute and including the available sizes, browsers can choose the most suitable version to download based on the device's resolution. This is particularly beneficial for HiDPI displays.

‍

While the WordPress media library creates thumbnails based on your settings, the original image remains untouched. If you want to resize images and save disk space by not keeping the original file, you can use a free plugin like Imsanity.

‍

Imsanity allows you to set a limit for image dimensions, ensuring that all uploaded images are constrained to a reasonable size that still meets the requirements of a typical website. This plugin integrates seamlessly with WordPress, functioning as if the contributor had already scaled the image to an appropriate size before uploading it.

‍

By resizing images to scale and leveraging responsive design capabilities, you can optimize your website's performance and ensure images are displayed correctly across different devices and resolutions.

‍

6. Automate Image Optimization with a WordPress Plugin:

In some cases, even with image optimization, large file sizes or numerous images on a page can still slow down site speed. To improve the user experience, it can be beneficial to optimize the load experience by implementing techniques that give the illusion of faster-loading images.

‍

One effective method is to load a Lower Quality Image (LQI) first, displaying a smaller version of the image while the full-size image loads. This provides users with a visual element to engage with while waiting for the complete image to load, creating the perception of a faster loading time.

‍

The "blur up" technique is a popular approach to implement this effect. It involves displaying a blurred version of the image initially and progressively transitioning to the sharp, high-quality image. By following a tutorial like the one on CSS-Tricks, you can learn how to apply this technique and enhance the user's perception of faster image loading.

‍

7. Lazy Load Your Site Images:

Another technique to enhance the perceived loading speed of your images is lazy loading. Unlike traditional loading methods, lazy loading focuses on loading only the images that are currently visible to the user, rather than loading all the images on the page at once.

‍

By implementing lazy loading, the images within the user's viewport are prioritized and fully loaded, while the remaining images are loaded as placeholders until the user scrolls to them. This approach ensures that the user sees the content they care about first, creating the illusion of faster image loading.

‍

Lazy loading is a powerful technique on its own, and when combined with other image optimization strategies, it can further boost site performance. With the Smush plugin available for WordPress sites, implementing lazy loading becomes even easier.

‍

By following these step-by-step image optimization tips, you can significantly improve your site's performance and speed.
