With the popularity and development of online shopping, product pictures on e-commerce platforms have become an important means for websites to attract users. The quality of product images is not only directly related to user experience, but also closely related to the conversion rate and sales of the website. For an e-commerce website based on PHP, cropping and compressing product images is undoubtedly an indispensable technology.

Why do we need to crop and compress product images?

It is necessary to display product images on e-commerce websites. However, product images are generally larger. If uploaded directly, the page loading speed will be slower and the user experience will also be affected. On the other hand, images of different dimensions and sizes can also cause difficulties in the storage and maintenance of the website. Therefore, cropping and compressing product images can optimize website performance, improve user experience, and make e-commerce platforms more efficient and sustainable.

Tips for cropping images

In e-commerce websites, product images often have different sizes and sizes. Generally speaking, the larger the image size, the better the quality, but it also takes up more storage space and bandwidth. Therefore, cropping product images is very necessary.

The following introduces two commonly used techniques for cropping pictures:

1. Manual cropping

Manual cropping is to manually select parts of the picture through image processing software such as Photoshop, GIMP, etc. Make a cut. This method results in the most accurate dimensions and highest quality. However, this method requires certain professional skills and time, and is very time-consuming for large-scale image processing.

2. Automatic cropping

Automatic cropping is to automatically crop parts of the picture through code. This method can save a lot of time, especially when working with large batches of images. For example, for a product list page, all product images can be automatically cropped to the same size, which can make the page more tidy and beautiful, and can also save storage space and bandwidth.

Tips of compressing images

After the cropping of the product images is completed, the next step is to compress the images. Compared to cropping, compression will have a certain impact on quality.

The following introduces several commonly used techniques for compressing images:

1. Image optimization tool

The image optimization tool is a convenient and fast way to process compressed images. Images can be processed and optimized using online tools like TinyPNG and Compressor.io. Using a tool like this, you can automatically compress your images so that the image quality is still great but the file size is reduced.

2. Picture format

Choosing the correct picture format can have a great impact on the quality and file size of the picture. PNG, JPEG and GIF formats are the most commonly used formats. The most widely used PNG format is 24-bit, which does not lose quality but has larger file sizes. The most widely used JPEG format is 70% quality, which can achieve higher quality and smaller file size. The GIF format is suitable for fewer colors and simple animations.

3. Crop excess areas

If a picture has a lot of white background or other unnecessary areas, you can delete these areas by manually cropping or using automatic cropping. . This will not only make the picture more beautiful, but also reduce the size of the picture file.

Conclusion

In e-commerce websites, the display of product pictures is crucial to promoting products. Therefore, it is essential to master the cropping and compression skills of product images in the PHP mall. Through cropping and compression, we can optimize website performance, improve user experience, increase conversion rate, and achieve the purpose of increasing sales.
