Optimize images, accelerate the website: AnqiCMS Large Image Automatic Compression Settings Guide
The website loading speed is one of the key factors for user experience, and it is also an important consideration for Search Engine Optimization (SEO).Large images are often the main culprits that slow down website loading speed.幸运的是，AnqiCMS 作为一个功能完善的内容管理系统，内置了一系列强大的图片优化功能，帮助我们轻松应对这个问题，让网站在提供丰富视觉内容的同时，保持流畅的访问体验。
Today, let's take a detailed look at how to set up automatic image compression and other image optimization options in AnqiCMS to speed up page loading.
一、Enable large image automatic compression, intelligent management of image size
Preventing large images from being directly uploaded to the website, occupying too many server resources, and slowing down page loading speed is the first step in image optimization.AnqiCMS provides a very practical feature——Automatic image compression.
This feature is located in the 'Content Settings' on the backend.Firstly, log in to your AnqiCMS backend management interface, find the 'Backend Settings' in the left menu bar, and click 'Content Settings'.In the content settings page, you will see an option named 'Whether to automatically compress large images'.
Select this option, and AnqiCMS will automatically detect the image size during image upload.If the size of the uploaded image is too large, the system will automatically compress it, thereby effectively reducing the file size of the image, reducing the transmission pressure on the server and the bandwidth consumption of the user, and significantly improving the page loading speed.By default, the system will compress the detected large image width to 800 pixels.
Of course, this default value is not unchanging.Below, there is an input box for 'auto-compress to a specified width'. You can flexibly adjust this value according to the actual design requirements and the width of the content area of the website.For example, if the maximum width of the content area on your website is 1200 pixels, setting this value to 1200 will ensure that uploaded images are both clear and perfectly adaptable to the layout, while avoiding unnecessary large sizes.This way, even users who are not familiar with image processing can ensure that the uploaded images will not become a burden on the website.
二、Start WebP image format, improve loading efficiency
Except for directly compressing the image size, using more efficient image formats is also an effective means to improve website loading speed.WebP is a modern image format developed by Google, which can provide smaller file sizes at the same quality compared to traditional formats such as JPEG, PNG, etc., thereby further accelerating image loading speed and saving storage space.
In the same 'Content Settings' page, you will also see an option for 'whether to enable WebP image format'.Enable this feature and all newly uploaded JPG, PNG, and other image formats will be automatically converted to WebP format in the background.It should be noted that this setting only takes effect for images uploaded after it is turned on, and the old images already uploaded to the website will not be automatically converted to the new format.
If you want to convert all historical images on the website to WebP format for comprehensive optimization, AnqiCMS also provides a convenient 'WebP Conversion Tool'.You can use this tool to batch convert existing images after enabling the WebP feature, to optimize the site's images and further accelerate the website.
三、Optimize thumbnail processing, unify beauty and speed
The 'Content Settings' section includes features such as 'Thumbnail Processing Method' and 'Thumbnail Size', which are designed for this purpose. You can choose from the following three thumbnail processing methods based on your actual needs:
- Scale proportionally by the longest sideThe image will maintain its original aspect ratio, scaling based on the longest side to ensure the image is displayed completely.
- Scale proportionally by the longest side with padding：The image will fill the blank areas while maintaining the aspect ratio to reach the set size, suitable for scenarios that require fixed-size picture frames.
- [en] : Crop to the shortest edge.The image will be cropped based on the shortest side to ensure the image covers the set size, but some content may be cut off.
After selecting the processing method, you can set a uniform width and height in the 'Thumbnail Size'.When you have adjusted the thumbnail size, you can also use the 'Batch Regenerate Thumbnails' feature to generate thumbnails for all uploaded images according to the new size and method, ensuring consistency and **performance** in website display.
By combining the image optimization features of AnqiCMS, you can build a website that is both rich in content and fast loading, providing users with an excellent browsing experience and laying a solid foundation for the website's search engine performance.Remember, image optimization is a continuous process. Regularly checking and adjusting settings will help your website maintain good performance.
Common Questions (FAQ)
Q1: After enabling the WebP format, can old browsers still display images normally?A: WebP format compatibility is already very good, mainstream modern browsers (such as Chrome, Firefox, Edge, Safari, etc.) already support it.For a small number of old browsers that do not support WebP, AnqiCMS usually has built-in fallback mechanisms, or you may need to make some compatibility handling in the template, but the vast majority of users will not encounter display issues.
Q2: What if I need to display the original size of the image after setting the automatic compression of the large image width?A: The auto-compression feature is mainly for images uploaded to the content editor, the purpose is to optimize page loading.If certain scenarios indeed require displaying the original image size, you can choose not to enable this feature, or upload the original image size to another location (such as a dedicated image hosting) and then introduce it through an external link.However, it is usually not recommended to directly display ultra-high-resolution images without optimization on the page for website performance.
Q3: What are the differences between the three thumbnail processing methods, and how should I choose?A:
- Scale proportionally by the longest side：Advantages are that the image content is the most complete, and it will not be cropped, but the final size may not be completely consistent. Suitable for lists that require high image integrity and do not need strictly uniform sizes.
- Scale proportionally by the longest side with padding：Advantages include strict uniformity of thumbnail dimensions and complete image content, but white edges may appear. Suitable for scenarios that require fixed width and height display and do not mind white edges.
- [en] : Crop to the shortest edge.：The advantages are that it can strictly maintain the uniform size of thumbnails, and the images can completely fill the area without any white edges, but it may crop off the edge content of the images.Suitable for scenes with high visual impact, where the central content of the image is prominent and the edge information is not important. Choose which method depends on your website design style and specific requirements for image display.
