Placeholder Image Generator

The Placeholder Image Generator creates custom placeholder images right in your browser using the HTML5 Canvas API. Set any width and height up to 2000×2000 pixels, choose background and text colors, and optionally add custom text—otherwise the dimensions are shown automatically. Use the quick presets to instantly generate common ad sizes (300×250, 728×90, 160×600) or social media dimensions (1200×630, 1920×1080). The preview updates live as you change colors or text. Download the generated image as PNG or JPEG with a single click. This tool is ideal for UI mockups, design wireframes, email templates, and any situation where you need a quick placeholder before final assets are ready.
