HTML Images & Formats

Pascual Vila

A picture is worth a thousand words, but only if it loads quickly. Mastering the<img> tag means understanding attributes and file formats.

The Image Tag

The <img> tag is a void element. It essentially acts as a placeholder that the browser fills with content referenced by thesrc attribute.

Formats Explained

JPEG is the king of photography. It uses lossy compression to reduce file size for complex images.PNG is lossless and supports transparency, making it ideal for logos.WebP offers the best of both worlds with superior compression.

Accessibility

Never forget the alt attribute. It is not optional. It is the voice of your image for those who cannot see it, and it helps Google understand your content.
