Knowledge Base
Differences between PNG, JPG, and WebP
PNG, JPG, and WebP are all image formats that can save gradient images, but they differ in compression method and file size.
- PNG：PNG uses lossless compression to preserve image quality, making it ideal for background images where you want to keep color transitions intact.
- JPG：JPG uses lossy compression to reduce file size at the cost of some quality, making it suitable for photos and when you need to minimize file size.
- WebP：WebP is a web-optimized format that creates smaller files than PNG or JPG and is supported by all major browsers, though older software may not open it.
How gradient direction is determined
For linear gradients, 0° points upward from bottom to top. As the angle increases, it rotates clockwise: 90° points left to right, and 180° points top to bottom. For radial gradients, colors transition from the center position to the farthest corner of the image.
