Review CSS structure
Use Extract CSS Variables, Extract CSS Media Queries, and CSS Formatter with URL inventories.
Clean copied rows
Send copied output to Remove Duplicate Lines, Sort Lines, or URL Parser.
What this tool does
Extract CSS URLs finds url() references in pasted CSS, removes duplicates, shows source lines, and runs locally in your browser without loading images, fonts, or other assets.
Common use cases
Extract url() asset references from pasted CSS, style tags, component styles, or copied source before asset inventory, performance QA, migration, or documentation cleanup.
Use Extract CSS URLs when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste CSS, style tags, theme files, component styles, or copied source that contains url() references.
- Choose whether duplicate URLs should be removed and whether URL entities and whitespace should be normalized.
- Review asset references with source lines, then copy the clean list for migration notes, performance QA, or asset inventory work.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
CSS URL extraction runs locally in your browser. Your pasted CSS is not uploaded, rendered, fetched, crawled, executed, stored, logged, or used to load assets.
