Description

Enter HTML directly or a URL to analyze HTML size and catch bloat like inline images, large React hydration state, or code duplication. Browsers assign a high priority to HTML document requests, so low-priority content like embedded images or JSON data can be prioritized over resources that are immediately render-blocking. Duplicated HTML usually compresses well when sent over the network. However, very large HTML responses (multiple megabytes) can still take a long time to parse.
