Free HTML Pretty Print Online
HTML Pretty Print takes a single-line or messy HTML file and rewrites it with clean indentation so the structure becomes obvious.
Using HTML Pretty Print, Step by Step
- Paste your compacted HTML into the left editor or drop an
.htmlfile onto the page. - Pick 2 spaces, 4 spaces, or a tab character from the indent dropdown in the toolbar.
- Switch the right pane to Tree view when you want a structural overview alongside the formatted code.
- Copy the formatted markup or save it as a file from the output header.
