FAQ & Limitations

Quick answers about Ultimate Web Scraper — what it can extract, free limits, pagination, logins, captchas, scheduling, and known limitations.

Capabilities

LinkedIn is not supported — it's blocked as a target in every tool, including for AI agents.
Shadow DOM and cross-origin iframes aren't reachable by element picking.
Browser-internal pages (chrome://, extension pages, non-http(s)) can't be scanned.
Content that requires interaction to appear (beyond scrolling/pagination) isn't captured; JS-rendered content is handled via configurable load waits.
Images download as individual files into one folder — not a ZIP.
Tables can't be merged with each other (column merge within a table is supported), and there's no Markdown export.
Local data is device-local. Uninstalling the extension or clearing browser data deletes local results; retention keeps the newest 100/500/1,000 tables (configurable). Cloud results persist in the dashboard.
