What is placeholder.com?

Placeholder.com is a free image placeholder service that generates solid-color images with a dimension label. You specify width, height, background color, and text color in the URL, and it returns a PNG image on the fly.

What is Picsum Photos?

Picsum Photos (picsum.photos) serves random, high-quality photographs from Unsplash at any size you specify. It is useful when you need realistic-looking photo placeholders rather than solid-color boxes.

How do I use the generated HTML?

Copy the HTML snippet and paste it into your HTML file. The tag includes the src URL, width, height, and an alt attribute so it is accessible and renders at the exact size you configured.

Can I use these images in production?

Placeholder images from these services are intended for development and testing only. Replace them with real assets before shipping to production.

Set any width and height, choose background and text colors, pick from multiple services (placeholder.com for solid-color labeled images or Picsum Photos for realistic random photographs), and instantly get a live preview. Copy the resulting embed code in your preferred format: HTML <img> tag, CSS background property, or Markdown image syntax. All dimensions and colors update in real time, making it easy to generate dozens of placeholder sizes for a responsive layout.
