Tips for 300x250 Images
Digital ad banners (300×250) need to be sharp and lightweight to maximize impressions while meeting ad network file size limits. Most ad networks accept JPEG and PNG under 150 KB. Design at exact dimensions to avoid distortion from scaling. High-contrast text and clear calls-to-action perform best at these small sizes.
After resizing: Use the Image Compressor after resizing to meet file size requirements without sacrificing visual clarity.
