0 / 30,000 characters. No upload, storage, or account required.
Preload link extraction workflows
Use preload link extraction when performance resource hints are mixed into pasted head markup and need a fast asset inventory.
Review related assets
Pair this with Extract Stylesheet Links and Extract Script Sources for a broader HTML asset list.
Inspect URL details
Use URL Parser when copied preload URLs include hosts, query strings, or cache parameters.
Clean copied output
Send copied rows to Remove Duplicate Lines, Sort Lines, or Filter Lines.
What this tool does
Extract Preload Links finds rel=preload href values in pasted HTML, includes the as type when present, removes duplicates, shows source-line context, and runs locally in your browser.
Common use cases
Extract rel=preload href values and resource as types from pasted HTML head snippets, build output, templates, and copied source before performance QA or asset migration review.
Use Extract Preload Links 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 HTML head markup, copied page source, theme templates, build output, or CMS snippets that contain preload link tags.
- Choose whether duplicate preload rows should be removed and whether HTML entities should be decoded.
- Review source-line context, then copy the clean preload list for performance QA, template review, or migration documentation.
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
Preload link extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, execute, or log the HTML text you paste.
FAQ
Does Extract Preload Links load the assets?
No. It only reads pasted HTML text and extracts visible rel=preload href values. It does not fetch, crawl, upload, store, render, or execute assets.
What output does it produce?
When a preload tag has an as attribute, the output includes the type followed by the href, such as font: /fonts/inter.woff2. Otherwise it outputs the href alone.
Can it extract stylesheet or script tags too?
This page focuses on rel=preload resource hints. Use Extract Stylesheet Links or Extract Script Sources for regular stylesheet and script dependencies.
