On the other hand, for graphics and logos with solid colors, it is best to use the PNG format, which offers higher uncompressed quality.
- Optimize image size: In addition to compressing images, it is important to resize them so that they fit perfectly into your website's design. This can be done using image editing tools to resize and crop images as needed. Remember that the larger the image size, the longer it will take to load in the browser of user.
- Friendly file name: When saving your images, be sure to use a friendly file name that reflects their content. This will not only facilitate the organization of your files, but it will also help search engines understand what the image is about and improve its visibility in search results.
- Use alternative text (alt text): Alt text is a short description displayed when an image fails to load or is interpreted incorrectly. It is important to include relevant and descriptive alt text for each image, as this not only improves the accessibility of your website for visually impaired users, but also provides additional information to search engines about the image content.
- Optimize image loading: In addition to optimizing the images themselves, it is also important to optimize the way they load on your website. A common technique is to use lazy loading, which means that images load as the user scrolls down the page, instead of loading all images at the same time. This helps reduce the initial loading time of your website and improves user experience.
- Test and analysis: After applying all the techniques mentioned above, it is essential to perform testing and analysis to ensure that your images load quickly and display correctly on different devices and browsers. Use online tools or plugins to analyze your website's performance and make adjustments if necessary.
