About Image Placeholder Generation

An image placeholder is a temporary image used in design and development to represent a final image before it's available. It helps in visualizing layouts, testing image responsiveness, and demonstrating design without needing actual image assets.

Why Use This Tool?

This Image Placeholder Generator simplifies the creation of custom image placeholders, making your design and development workflow more efficient:

  • Rapid Prototyping: Quickly fill image sections to visualize your design early in the process.
  • Consistent Testing: Use consistent placeholder images to test layout responsiveness and image sizing across different devices.
  • Customization: Specify width, height, colors, and add custom text directly onto the placeholder image.

Common Placeholder Sizes

  • 150×150 (thumbnail), 300×250 (card), 400×300 (content image)
  • 728×90 (banner), 1200×628 (social link), 1080×1080 (square)
  • 1920×1080 (hero), 2560×1440 (wide banner)

Enter your dimensions and optional text, click Generate Image Placeholder to create an SVG data URI instantly. Copy the URI, or download a PNG.

5 Fun Facts about Placeholders

SVGs stay pixel-perfect

A single SVG placeholder scales to any size without blur. One tiny data URI can cover all your breakpoints.

Vector magic

Base64 isn’t required

You can drop Base64 and embed raw SVG text in a data URI. Percent-encoding is enough—and smaller.

Lean URIs

Aspect ratio helper

A placeholder with the right width/height keeps layout shifts away while real images load—CLS insurance for free.

Layout stability

Low-ink skeletons

Neutral gray (#e5e7eb style) feels “inactive” to users. Brighter colors make placeholders look like real content.

UI psychology

Use text as a hint

Overlay text like “1200×628 cover” or “Hero” doubles as documentation in design handoffs.
