If a native ad consistently displays with poor image quality despite meeting the specified dimensions, what is the *most likelytechnical reason, and how do you rectify it?

The most likely technical reason for a native ad displaying with poor image quality, despite meeting the specified dimensions, is that the image file size is too small, or the image has been compressed excessively, resulting in a loss of detail and sharpness. While the dimensions (width and height in pixels) define the physical size of the image, the file size (measured in kilobytes or megabytes) determines the amount of data used to represent the image. A smaller file size often means a lower quality image due to compression algorithms removing details to reduce the file size. For example, an image with dimensions of 1200x628 pixels might meet the platform's requirements, but if the file size is only 20KB due to heavy compression, it will likely appear blurry or pixelated. To rectify this, you need to ensure that the image is saved with sufficient quality settings to maintain detail while still meeting the platform's file size limitations. This involves adjusting the compression settings when saving the image in a photo editing program (like Adobe Photoshop or GIMP) to find the optimal balance between file size and visual quality. Increasing the image resolution beyond the minimum requirement can also improve perceived quality, as the image will be downscaled, which can reduce aliasing and improve sharpness. Also ensure the image is saved in a lossless format, like PNG, rather than a lossy one, like JPG, to avoid compression artifacts, if feasible given file size constraints.
