When uploading main pictures for e-commerce, you need to pay attention to the following points to ensure that the picture is clear:

Choose high-definition pictures: When shooting or selecting main pictures, you need to choose pictures with higher pixels and better clarity. Generally speaking, the higher the pixels, the clearer the picture, but it will also take up more storage space.

Keep the picture proportions consistent: When uploading the main picture, you need to keep the picture proportions consistent to avoid stretching or deformation of the picture. Generally speaking, the e-commerce platform will stipulate the proportions and size of the main picture, and you need to operate according to the requirements.

Adjust the brightness and contrast of the picture: Before uploading the main picture, you can adjust the brightness and contrast of the picture appropriately to improve the clarity and quality of the picture.

Avoid picture compression: When uploading the main picture, you need to avoid compressing the picture to avoid affecting the clarity and quality of the picture. If the picture is too large, you can choose to crop or compress the picture, but you need to keep the clarity and proportions consistent.

Choose the right file format: When uploading the main image, you need to choose the right file format. Generally speaking, the commonly used image formats are JPEG, PNG, GIF, etc. Different formats have different characteristics and advantages and disadvantages, and need to be selected according to the specific situation.

In summary, when uploading the main image of an e-commerce website, you need to choose a high-definition image, keep the proportions consistent, adjust the brightness and contrast, avoid compression, and choose the right file format.
