Format, beautify, and minify XML instantly in your browser. Pretty-print with 2-space, 4-space, or tab indentation, or compress to a single line — with a basic validity check and one-click copy. No sign-up, nothing stored.
XML (Extensible Markup Language) is a text format for structuring data with nested tags. Raw XML from APIs, exports, or config files often arrives on a single line or with inconsistent spacing, which makes it hard to read. An XML formatter reorganizes that whitespace so the structure becomes obvious — without ever touching your actual data.
This tool offers two modes. Beautify pretty-prints the document with indentation that increases inside each element and decreases when it closes. Minify removes whitespace-only text between tags and collapses the document to a compact single line, ideal for shrinking payloads.
Pretty-print XML with clean, nested indentation so structure is easy to read and review.
Strip insignificant whitespace between tags and collapse the document to a single compact line.
Choose 2 spaces, 4 spaces, or tabs to match your project's coding style for beautified output.
Unbalanced or mismatched tags are flagged inline while the tool still attempts best-effort formatting.
Output updates instantly as you type or paste — no buttons to press, with copy and download ready.
All processing happens in your browser. Your XML is never uploaded, logged, or stored anywhere.
Drop raw or messy XML into the input panel — the formatter reads it instantly.
Choose Beautify to pretty-print with indentation, or Minify to compress to a single line.
For beautify, select 2 spaces, 4 spaces, or a tab to match the style your team uses.
Grab the formatted result with one click, or download it as a .xml file.
Beautify pretty-prints XML by placing each tag on its own line with indentation that reflects nesting depth, making the structure easy to read. Minify does the opposite: it removes whitespace-only text between tags and collapses everything to a single compact line to reduce size.
No. Only insignificant whitespace between tags is adjusted. Text inside elements, comments, and CDATA sections is preserved exactly as written, so your data is never altered.
It performs a basic structural check for obviously malformed XML, such as unbalanced or mismatched tags, and shows a clear inline warning when it finds one. It is not a full schema or DTD validator, but it still attempts a best-effort format so you can see the result.
Yes. The tokenizer treats XML declarations, comments, and CDATA sections as atomic blocks, so their contents are never re-indented or corrupted during beautifying or minifying.
No. The XML Formatter runs entirely in your browser using client-side JavaScript. Your XML never leaves your device — nothing is transmitted, logged, or stored.
Yes. When beautifying, you can pick an indent size of 2 spaces, 4 spaces, or a tab character to match whatever convention your project follows.
