Extract SVG Mask IDs
Extract mask IDs from pasted SVG markup without rendering artwork, loading assets, or uploading code.
0 / 30,000 characters. No upload, storage, or account required.
SVG mask ID extraction workflows
Use this extractor when pasted SVG markup needs a browser-local inventory of mask definitions before effect cleanup, icon migration, or documentation.
Audit effect definitions
Pair mask IDs with Extract SVG Filter IDs, Extract SVG Clip Path IDs, and Extract SVG Gradient IDs.
Review icon structure
Use Extract SVG IDs, Extract SVG Use References, and Extract SVG Path Data with copied SVG exports.
Clean copied output
Send copied mask rows to Remove Duplicate Lines, Sort Lines, or Normalize Whitespace.
What this tool does
Extract SVG Mask IDs finds mask definition IDs, removes duplicates, shows source lines, and runs locally in your browser.
Common use cases
Extract mask id values from pasted inline SVG icons, illustrations, sprite markup, design exports, and copied source before effect audits, icon cleanup, migration, or documentation.
Use Extract SVG Mask IDs 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 inline SVG icons, illustrations, symbol sprites, or copied exports that contain mask definitions.
- Choose whether duplicate mask IDs should be removed and whether output should be normalized.
- Review mask IDs with source lines, then copy the clean list for effect audits, sprite cleanup, migration notes, or 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
SVG mask ID extraction runs locally in your browser. Your pasted SVG is not uploaded, rendered, fetched, crawled, executed, stored, or logged. Assets and pages are not loaded.
FAQ
Does Extract SVG Mask IDs render masks?
No. It reads pasted SVG text only and extracts mask id values. It does not render, execute, fetch, crawl, upload, store, or log snippets.
Does it load masked images or assets?
No. It inventories mask definitions from pasted markup only and never loads images, files, external pages, or referenced assets.
When is this useful?
Use it while auditing SVG masks, checking duplicated mask IDs, documenting icon effects, or preparing SVG cleanup notes.
