If you are considering optimizing the performance of the website, you will encounter some performance technologies, such as image compression compression Essence Reducing the size of network photos can help you get a few millisecond loading time.
When optimizing the image, you can choose two types of compression: loss and lossless compression . The two have their own advantages and disadvantages. As the owner of the website, you should evaluate the two before making a decision. Don’t worry: we have provided you with a guarantee.
Before we start, you should know that the image does not have a single best format or \”quality settings\”. All of this is attributed to what kind of damage or loss of algorithms used to optimize each image. In addition, your specific needs.
Reading this article, you will understand all the knowledge about these two types of image compression.
What is the loss of image compression and its working principle
Damage compression means reduced image size, while some data in the original image files are eliminated.
If you ask if you have damaged compression, the answer is: No.
The process of damaged image is irreversible . After compressing the image in this way, you will not be able to return.
Okay, in most cases you can’t go back. You are lucky: using Imagify WordPress plug -in, if you are not satisfied with the result, you can return to the original picture.
The irreversibility of compression and compression causes a question:
Why use it?
That’s what happened.
When optimizing the source code and other data on the page, it is important to ensure that compression does not change the code. An error data may be interrupted with your code. For other data types, such as images or videos, you can compress it and present the \”approximation\” of the original data without losing its meaning. In other words,
No user will notice that your image is compressed
(unless you compress the same image over and over again).
The fact is that we have been using damaged image compression on the Internet.
Damage image format
The most common damaged image format is JPEG and GIF. However, our eyes did not notice the difference between JPEG, GIF, PNG or other formats.
Due to the working method of our eyes, the image is an ideal choice for compression. Our eyes are sensitive to different colors. This is used for image compression because we compress some colors more than other colors.
The advantages, advantages, and disadvantages of loss of compression
At this time, you may want to know what the advantages and disadvantages of loss of compression are.
The biggest benefit of damaging compression is that it significantly reduces the size of the image file. On the other hand, the biggest disadvantage is that this is achieved under the condition of quality loss -although as we explained, this is almost difficult to detect. Most available compression tools allow you to choose the degree of compression used on the image.
For loss compression, everything is to find a good compromise solution between the size and image quality.
For example, imagified will allow you to choose between three compression levels: normal, radical and super strong. Radimity and super are a powerful level, and will reduce the size of the image. At the same time, these levels may reduce image quality in some way.
IMAGIFY compression prompt : The radical level is to reduce the size and does not affect the size of the image and it does not affect the impact The most balanced level between its quality.
When should we use damage compression? Remember, usually 50% of image compression will reduce the file size by 90%.
If your goal is to reduce the size of the image file, the compression of 80%will only reduce by 5%, which will reduce your total amount to 95%.
For most of us, this compromise is not worth it, because compression may reduce the image to a significant degree
.
Most online image optimization tools use image compression algorithms to solve these restrictions to provide clear images of fast loading. Free trial imagify to see how the plug -in work works!
Is it suitable for you?
The image optimizer using Imagify runs fast testing on your website page. In this way, you can the compressed image without changing the original image.
What is non -destructive image compression and its working principle non -destructive pressure pressure pressure pressureSmall means that you can reduce the size of the image without losing any quality. Generally, this is achieved by deleting unnecessary metadata from the JPEG and PNG files. The reason why we say \”usual\” is because other compression algorithms, such as Imagify, can use other compression opportunities without sacrificing the quality of the image.
The best non -destructive image format
The most common non -destructive image format is GIF, PNG and BMP. However, according to their optimization methods for Web, these formats may have slight quality losses. Don’t worry: our eyes cannot recognize it.
The advantages and benefits of lossless compression
The biggest benefit and advantage of non -destructive compression is that it allows you to reduce the size of the file while maintaining the quality of the image. This is a win -win situation: you will improve the performance of the website and will not affect the quality of the image.
When should you use non -destructive image compression If you want to keep it For the quality of the image, you should choose non -destructive compression instead of damaging compression. If you choose to compress the image without loss, the price is that you will have a larger file. Therefore, you need to find other methods to optimize the performance of your website. Converting your image to a webp format and selecting the best cache plug -in for WordPress may be a good starting point!
Will image compression be reduced?
At this time, you should know that image compression may not necessarily reduce the quality of the image. In general, providing some quality loss image compression is a loss type. However, it also depends on the image compression algorithm. As long as you find the correct compression level, the human eye will not detect any decline in the quality of the photo.
We recommend that you try different solutions as needed, and we will explain in the next section.
Which compression method should you choose?
Selecting the correct compression level depends on many factors. You should first consider your needs.
If high -quality images are important to your business and customers, then you should consider non -destructive compression. However, if your website needs very fast, you should consider positive image optimization. According to the CMS you use, you will need to optimize some settings to ensure that the image is compressed under your complete control. Don’t hesitate, study such as wordpress plugTools such as pieces to help you complete your work.
WordPress specific image compression
If you are using WordPress, you should know that it will compress your image by default. When WordPress creates a preview image, your JPEG image is compressed to 82%. You can add or reduce the compression level of CMS in the function.php file.
We do not recommend beginners or intermediate WordPress users. Instead, you should only work hard to enhance what WordPress has done in image compression.
The blogger’s image compression According to the type you run It can become a battlefield with non -destructive. You should check the most commonly used image format to help you determine your needs. The following is a fast review of the main image format we tend to use on the Internet: JPEG -photos or design of the most suitable characters, place or things.
PNG – The most suitable image with a transparent background
GIF -the most suitable animation GIF. Otherwise, use JPG format
Webp -the best format for obtaining smaller images and maintaining the same quality. Please note that you must convert the image to a webp because you cannot upload them to WordPress.
The second thing you must remember is that you can upload a picture, but your CMS will create more pictures. WordPress usually creates three to five variants for each image. Therefore, image optimization will soon become a major event for your blog.
If you are not sure which route you should take, we recommend choosing damage compression [ 123]. Of course, you must first test to ensure that the results meet your standards. Is it uncertain whether the image will drag your performance? Get a page from your website, put them into the online optimizer, and check the results! If you intend to use Google Page Speed \u200b\u200bInsights, you need to consider using a specific algorithm to analyze your image. Sometimes, your image has been perfectly optimized with another algorithm that has not been detected by Google tools. This may lead to false positive results, telling you that optimization has already been optimizedOptimized image. What is the best image compression of e -commerce? Images usually occupy most of the ed bytes on the page. Over the years, this trend has been steadily increasing, especially for online stores. Optimized images can affect e -commerce websites because customers want to quickly find what they want. The challenge is to find a way to provide shopping high -resolution photos for shoppers, while maintaining fast loading time.
There are many strategies to optimize photos. Image compression tools, photo processing or PHP script can usually help you achieve appropriate performance required for online stores. If you are using Shopify, you should know that the image will automatically compress and optimize. If you use Woocommerce, you should rely on the WordPress plug -in dynamically optimizing the image when adding the image to the online store.
Photographer’s image optimization If you are a photographer, we suggest you show high -quality images. This means closing the default image compression in WordPress. However, you can still use non -destructive images to optimize the image. If you intend to use Imagify and the recommended compression settings to \”normal\”, this can ensure that you will maintain the image quality you are looking for. Damage and loss is your choice Find out what your website needs, test and select the most suitable for you. Keep in mind that you always pay attention to your image quality and loading speed to ensure that you will not lose your visitors or customers in this process.
