For Uniapp, images obtained from network requests are generally in the following formats:

1. JPEG format: JPEG is a commonly used lossy compression format that can greatly reduce the file size of images. Size, a format commonly used to store photos and images. Images in JPEG format can support resolutions up to 9000x9000 pixels without distortion.
2. PNG format: PNG is a lossless compression format that can maintain the high definition of images and is generally used for network transmission and image production. Pictures in PNG format are not lost, can achieve transparency effects and support the mixing of multi-layer image transparency, so they are widely used in interface design and other fields.
3. GIF format: GIF is a dynamic image format widely used on web pages and mobile devices. GIF only supports 256 colors, can use transparency, and the file size of this format is generally small, so it is often used to create dynamic images and animations.
4. WebP format: WebP is a new image compression format developed by Google. It can reduce image size by nearly 40% while maintaining image quality. Images in WebP format are usually much smaller than files in other formats, so the user experience speed can be greatly improved.

If you have strict requirements on image quality, it is generally recommended to use images in PNG format; if you are concerned about file size, it is recommended to use images in JPEG or WebP format; if you need to create dynamic images or animations, you need to choose images in GIF format.
