You can use any online image compressor to reduce file size. All images should be in .jpg or .png format and their size must not exceed 3МВ. You can use any online image compressor to reduce file size. **Recommended Image Size**: This is not the actual size of the container — it has the same aspect ratio as the container, but takes into account higher PPI to maximize quality. **Aspect Ratio**: This is either **certain** or **flexible**. **Certain** means you have to upload an image of exact proportions. If an image’s aspect ratio doesn’t match the container’s aspect ratio, it will either be cropped or the empty space will be filled with a background color. **Flexible** means you can ignore the recommended image size. **Container Behavior**: This determines the vertical and horizontal behavior in relation to your browser window. **Fill** means the entire available width or height is filled, with the other axis scaling proportionally. If we've included a min/max parameter, that means resizing will stop once the limit has been reached. **Fixed** means the image size doesn’t change, though it may crop or appear as your browser window increases/decreases. **Absolute position**: This means that the image doesn’t push/pull surrounding content when resized.
