Full-page gotchas

Full-page screenshots (full_page: true) capture the whole scrollable page, but tall or dynamic pages can come back cut off, stretched, or with repeated sticky headers.

Duplicated headers or footers

Urlbox stitches several sections together, so fixed elements can repeat in each one. freeze_fixed (default true) detects and captures them only once — leave it on. If a site fools the heuristic, try the stitch settings below.

Cut off or stretched

• full_page_mode — stitch (default, most accurate) vs native (faster). Try native if stitching misbehaves.
• detect_full_height — handles 100vh hero sections that would otherwise stretch out of proportion.
• max_section_height — cap the height of each captured section.
• scroll_delay — give lazy content time to load between scroll steps.
• max_height — cap the total height of very long pages.

{  "url": "https://example.com",  "full_page": true,  "full_page_mode": "stitch",  "scroll_delay": 500}
