How It Works
Enter width and height in pixels. Common sizes: 300×250 (banner), 1200×630 (social media), 800×600 (blog).
Pick colours that give good contrast so the placeholder dimensions are readable in your design mockup.
By default it shows the dimensions. Replace with anything — "Hero Image", "Product Photo", or your client's name.
Download as PNG for offline use, or copy the generated URL to embed the placeholder directly in your HTML.
