To avoid blurry or pixilated images: 

• Use high-resolution images—at least 300 DPI (dots per inch).
• Avoid screenshots or low-quality images from the internet.
• When scanning documents or photos, set your scanner to 300 DPI or higher.
• Don’t enlarge small images; it’s better to start with a larger original.
• Use clear, original image files (JPG, PNG) directly from your phone or camera.
• Avoid resizing small images to make them bigger—this causes pixelation.
• Make sure photos are taken in good lighting and are in focus.
