## Best Optimization Method

### Set an appropriate color mode.

* Use the RGB color mode to easily identify any potential color deviation issues.
* When exporting image files, be sure to check “Color Space” → “Convert to sRGB”, and after exporting, verify whether there is any color deviation in the image.

### Choose an appropriate image size

* Estimate in advance how the image will be displayed in the scene.\
  \
  For example, if you are creating a 2D label in a 3D scene and expect its maximum display width to be one-fourth of the device screen width, you can set the image width to 270 px (based on an estimated width of 1080 px for mainstream high-resolution devices).

### Set an appropriate image resolution

* It is recommended to set the image resolution to 72 PPI.

### Choose an appropriate image format

* If the image contains transparent areas, choose a format that supports transparency (such as PNG or WEBP)
* If the image does not contain transparency, it is recommended to export it as JPG or JPEG to achieve a smaller file size.

### Optimize image compression

* It is recommended to upload the image to the image compression platform TinyPNG for compression processing: [Click here to use it now.](https://tinypng.com/)

After compression, verify the colors and sharpness again to ensure that the compression does not affect the main visual information.
