HTML <picture> Tag: Definition, Syntax, and Examples

What is HTML <picture> Tag?

The HTML picture tag is used to display responsive images based on screen size, device type, or specific conditions. It allows developers to serve different image versions for mobile, tablet, and desktop without affecting performance. The picture tag contains multiple source tags, each with its own media conditions, while the img tag inside works as a fallback. This tag is important because it improves loading speed, enhances user experience, and optimizes SEO by delivering appropriately sized images. It is commonly used in modern websites, especially for responsive layouts, high-quality visuals, and performance optimization.

Syntax of the HTML <picture> Tag

plaintext
<picture>
  <source srcset="image-small.jpg" media="(max-width: 600px)">
  <source srcset="image-large.jpg" media="(min-width: 601px)">
  <img src="image-default.jpg" alt="Responsive Image">
</picture>

The picture tag starts with picture and ends with picture. Each source tag inside contains conditions, and img acts as a fallback image.

Examples of HTML <picture> Tag

Example 1: Basic HTML Picture Tag

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

<picture>
  <source srcset="small-photo.jpg" media="(max-width: 600px)">
  <source srcset="large-photo.jpg" media="(min-width: 601px)">
  <img src="default-photo.jpg" alt="Nature Image - Scholar247">
</picture>

</body>
</html>

In this example, smaller screens will load small-photo.jpg and larger devices will load large-photo.jpg. If neither matches, default-photo.jpg is displayed.

Example 2: SEO Optimized Picture Tag

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

<picture>
  <source srcset="laptop-small.webp" type="image/webp" media="(max-width: 500px)">
  <source srcset="laptop-large.webp" type="image/webp" media="(min-width: 501px)">
  <img src="laptop-default.jpg" alt="Professional Laptop Image for Tech Guides - Scholar247">
</picture>

</body>
</html>

This example uses WebP formats for faster loading and includes SEO-friendly alt text. It helps boost page performance and rankings while delivering better-quality images.

Attributes of the HTML <picture> Tag

The picture tag does not support any attributes directly.
However, the source and img tags inside picture use attributes such as:

• srcset: Defines the image file(s).
• media: Applies conditions like screen width.
• type: Specifies file format (such as image/webp).
• alt: Provides descriptive text for accessibility and SEO (img tag only).
• src: Sets the default image (img tag only).
