What this tool does
Extract Image Dimensions finds width and height attributes on pasted HTML image tags, labels rows with alt text or src values, removes duplicates, shows source lines, and runs locally in your browser.
Common use cases
Extract width and height attributes from pasted HTML image tags, CMS output, article markup, component snippets, or copied source before layout QA, performance review, migration, or documentation cleanup.
Use Extract Image Dimensions 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 image markup, CMS output, article HTML, component snippets, or copied source that contains img tags with width or height attributes.
- Choose whether duplicate dimension rows should be removed and whether labels, source URLs, and dimensions should be normalized for comparison.
- Review image dimensions with source lines, then copy the clean list for layout QA, migration notes, performance review, or documentation handoffs.
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
Image dimension extraction runs locally in your browser. Your pasted HTML is not uploaded, rendered, fetched, crawled, loaded, executed, or stored.
