Mark AI Studio

Mark Studio resizes any ad to any screen size. Upload an image or video, enter a width and height, and download the result at full quality. Key features: • Smart cropping for close aspect ratios • Full layout rebuild for very different shapes • Images and video supported • Full-quality output with no downscaling or squashing • No preset sizes required, so you can set any dimensions • Free access with Google sign-in • Private account that keeps your work together When the target shape is close to the original, Studio crops the ad to fit while keeping the important content in view. When the new shape is very different, such as turning a wide banner into a tall vertical format, Studio re-lays the ad so text, logos, and visuals are arranged to suit the new size instead of being stretched or squeezed. Because you choose the exact dimensions, you are not limited to a fixed list of presets. Every export keeps full resolution. Your files are never downscaled to make them fit, and nothing is posted anywhere on your behalf, so you control where each version goes. The simple upload, size, and download flow means you can produce a full set of placements in minutes rather than opening design software for each one. Built for marketers, media buyers, agencies, and small business owners who run ads across websites, apps, social feeds, and digital signage. It is also useful for creators who need one campaign asset adapted for many screens without rebuilding it from scratch.
