What does pretty-printing HTML mean?

Pretty-printing adds indentation and line breaks to HTML code so the nested structure is clearly visible to a human reader.

Does pretty-printing affect page load speed?

Slightly — extra whitespace adds a few bytes. For production use, minify the HTML afterwards to remove the whitespace.

Printing code for offline review

Before a code walkthrough meeting, pretty-print all HTML files so reviewers can follow the nested structure without a code editor.

Pro tips

Get better results with these expert suggestions:

Use 4-space indent for printed output

When printing or screenshotting HTML for documentation, 4-space indentation reads better on paper or in slides than 2-space.

Preserve comments before pretty-printing

The pretty printer keeps your HTML comments intact. Use comments to annotate sections before pretty-printing for teaching examples.

Combine with syntax highlighting

After pretty-printing, paste the result into a syntax highlighter (like Carbon or Highlight.js) to create polished code screenshots for presentations.
