Paste XML, choose pretty or minify, copy the result. Runs entirely in your browser.
Drop your XML payload — SOAP, RSS, SVG, config files — into the textarea.
Pretty print for readability with configurable indent, or minify to strip inter-tag whitespace for compact transport.
Click Copy to grab the formatted output.
In-depth guide
Paste XML and toggle between human-readable indented output and compact minified form. Handles SOAP envelopes, RSS feeds, configuration files, SVG and any other XML dialect. Everything runs locally; CDATA, comments and processing instructions are preserved.
<!-- … -->) and processing instructions (<?…?>).When to reach for it. Use it to indent and inspect XML, SVG or RSS so the structure is readable at a glance.
When something else is better. It assumes well-formed input; it won’t validate against a DTD or XSD schema.
The pitfall to watch. Reformatting whitespace inside elements where whitespace is significant (some XML, and SVG text) can subtly change rendering.
Everything runs on your device. The values you enter are processed locally in this browser tab — EpitomeTool does not send your input to a server, store it, or log it. That means you can use the tool offline once the page has loaded, and refreshing the tab wipes the slate.
No. Formatting runs in your browser — safe to paste sensitive configs, SOAP envelopes or RSS feeds without leaking them.
No — it's a structural pretty-printer. It tokenises tags, comments, CDATA, doctypes and declarations, then re-indents. Malformed XML may produce odd output but won't error.
Yes — comments, CDATA blocks, processing instructions and DOCTYPE declarations are kept verbatim, just re-indented.
Attributes are preserved exactly as written, including their quote style and order. We don't normalise <code>'</code> to <code>"</code> or reorder for sorting.
Minify strips whitespace between tags and collapses runs of whitespace inside text content. Useful for embedding XML into a JSON payload or shrinking before transmission.
No — this is a layout tool, not a healer. If your XML is malformed, fix it in your editor or a real parser first.
