• logo

• 圖標(biāo)

• 邊框和裝飾

壓縮率

為了加快加載速度，當(dāng)圖片顯示在您的在線商店上時(shí)，Shopify 會(huì)對(duì)這些圖片進(jìn)行壓縮。壓縮圖片意味著減小文件大小，從而可以更快地加載頁(yè)面。通過壓縮，更多圖片可以存儲(chǔ)在給定數(shù)量的磁盤或內(nèi)存空間中。此外，還大幅減少了訪問圖片所需的時(shí)間。壓縮可能會(huì)導(dǎo)致圖片的質(zhì)量發(fā)生變化，具體取決于圖片的格式、大小和原始質(zhì)量。

壓縮后的 Shopify 圖片質(zhì)量等級(jí)如下所示：

• JPEG：65% 到 90% 之間

• PNG：90%

• GIF：質(zhì)量沒有變化

對(duì)于 JPEG 圖片，壓縮圖片的質(zhì)量級(jí)別取決于原始 JPEG 圖片的質(zhì)量以及輸出大?。?/p>

When to use JPEG images

JPEG images are ideal for photography and other still images with complex colors. The JPEG format has a palette with millions of colors. JPEG also has lossy compression, which can help to keep page loading times fast without a noticeable loss in image quality.

• products

• banners or slideshows

When to use PNG images

PNG images are ideal for graphics and icons with flat colors and without gradients. The PNG format is also able to support transparency.

Use the PNG format for the following kinds of images:

• logos

• icons

• borders and trims

Compression rates

To keep load times fast, Shopify compresses images when they're displayed on your online store. Compressing an image means reducing its file size to allow for faster loading. With compression, more images can be stored in a given amount of disk or memory space. Additionally, the time required to access the images is greatly reduced. Compression might result in a change in image quality, depending on your image's format, size, and original quality.

Shopify's image quality levels after compression are as follows:

• JPEG: Between 65 - 90 percent

• PNG: 90 percent

• GIF: no change in quality

For JPEG images, the quality level of a compressed image depends on the quality of the original JPEG image as well as the output size:
