Images can enhance the content of a website. It is very important to compress files to prevent unnecessary use of disk space, but it is very important to reduce the performance of the site. In order to optimize the image correctly, it is recommended that you understand the difference between loss compression and lossless compression. This issue will start with loss compression and lossless compression. Then, discuss when to use loss compression and lossless compression on the WordPress site. Let’s go! What is YouTube channel subscription loss compression? Loss compression reduces file size by deleting as much data as possible. As a result, some quality may be reduced, resulting in reduced image quality. However, when using balanced compression rate, most of the lost information should not be seen by visitors.
Loss compression is developed for a variety of file formats. It is most commonly used in JPEG (Joint Photographic Experts Group) and GIF (Graphics Interchange Format) formats. However, this compression method can also be used for audio and video files. The following is an example of loss before and after compression. On the left is 347kb of raw data. The size of the right image is reduced by 52% to 163KB. As you can see, although the file size is greatly reduced, there is no significant difference in appearance. However, different compression levels will affect the quality of compressed images.
The same principle applies to audio files. For example, loss compression can be used to reduce the size of MP3 files. However, this may reduce the audio clarity of the process. Advantages and disadvantages of loss compression the main advantages of loss compression are data elimination and size reduction. Creating smaller file sizes can improve site performance and load time. The result is improved user experience (UX) and search engine optimization (SEO). On the contrary, loss compression has several disadvantages. First, the file cannot be restored to its original format. That is, the process cannot return. In addition, data deletion may reduce image quality.
Overall loss compression is a compromise point. The smaller the file, the faster the performance. However, the more data is lost, the worse the image quality. What is lossless compression? Unlike lossless compression, lossless compression does not delete important data from the image file. Instead, delete metadata and unimportant information that has no impact on the appearance or quality of photos. This compression method may help to make the file size slightly smaller, but it usually makes little difference. The two most popular file formats related to lossless compression are compressed (zip) archive files and PNG (mobile network graphics) images. Lossless compression is developed for text, image and audio. In fact, some of today’s largest streaming services, such as Apple Music and spotify, use lossless compression of audio files.
Advantages and disadvantages of lossless compression the main advantage of lossless compression is that there is no need to worry about reducing the quality of photos or making them look like pixels. Unlike lossy compression, images can be restored to their original format without losing data. But there is an important drawback. The data retention capacity of lossless compression is very small. This compression method will not reduce the data size, so it will not save too much storage space. If WordPress sites use lossy compression and lossless compression, the most suitable compression method for the site depends on the file format used in some cases. For example, PNG is best suited for logos, illustrations, icons, and text with a transparent background. But most standard images on the web are JPEG.
Png recommends lossless compression. In contrast, the loss is JPEG
More suitable for. When WordPress uploads these photos to the media library, it will automatically compress JPEG images (file size can be reduced by up to 82%). functions. You can edit the PHP file to adjust this compression level. However, this method is not recommended if you are not familiar with code operations. Regardless of the default settings, you can further optimize your files by lossy or lossless compression. You can use image editing software, such as word press image optimization plug-ins such as Adobe Photoshop or imagine, WP Smush or shortpixel.
You can also use free online tools, such as tinypng. Now that you have a better understanding of loss compression and lossless compression, it’s time for WordPress to discuss when it’s best to use each method. As we discussed, these two compression types have their unique advantages and disadvantages. If WordPress uses lossy compression, disk space and bandwidth are the biggest problems. It is best to use lossy compression on the website. In order to speed up the site, Google recommends compressing the loss through the word press plug-in. You can also use gzip compression to further shrink the file.
In most cases, lossy compression is recommended for word press images. Data loss is hardly obvious, but it can greatly improve the loading time. Therefore, this method is very suitable for e-commerce stores, product portfolio websites and blogs. For example, loss compression can optimize product image and micrograph throughout the store. It can also be used on pages with standard blog posts and descriptive photos. In other words, unless the image is magnified in detail according to the compression level used, there is usually no significant difference in quality. Compression severity can also be selected in general.
For example, imageify allows you to select the optimization level based on the required compression strength. Male loss compression is best for word press images because most people don’t feel the quality degradation. Our eyes have multiple sensitivities to color and brightness. The compression algorithm uses the method of human image processing, which can hardly detect data deletion and quality degradation. If WordPress uses lossless compression, usually lossless compression is most suitable for images with more text and images with transparent background. Raw, BMP, GIF and PNG file formats are recommended.
If you are worried about the degradation of image quality, it may be better to choose lossless compression. Reduce file size while maintaining a clear appearance of the image. Lossless compression can make sense even if the site relies heavily on visual content such as images and websites. In this case, other methods can be used to optimize image and site performance, such as using content transfer network (CDN). Optimization conclusion image file is an effective method to improve the speed and performance of word press site. However, it may be difficult to determine loss compression and lossless compression. On the other hand, you may want to save disk space. On the contrary, I don’t want to damage the appearance and quality of the content.
As discussed in this post, both loss compression and lossless compression have advantages and disadvantages. Since you can significantly reduce file size without deleting compelling data, loss compression is recommended for most websites. However, if image quality is more important than loading time, lossless compression may be better. Is lossy compression a problem with lossless compression?
