How do I use this XML formatter online?

Paste your XML, leave Format XML selected, choose 2 or 4 space indent, and copy the indented result. Everything runs in the browser - nothing is uploaded.

Is this also an XML minifier online?

Yes. The same page minifies XML: comments and whitespace-only text collapse while element structure and text content stay intact. Use minify for embeds, env blobs, and compact fixtures.

Is my XML uploaded to a server?

No. Parsing, formatting, and minifying run only in your browser. Safe for configs and feeds that name real hosts or include private markup.

What happens when the XML is invalid?

You get an error with the line and column of the first problem - unclosed tags, mismatched closers, broken comments, or unclosed attribute quotes. Fix that spot and try again.

Do comments survive format and minify?

Format keeps comments by default. Minify drops them by default. Use the Keep comments checkbox when you need in either mode.

Can I format SVG and RSS?

Yes. SVG and RSS are XML. Load the SVG or RSS sample, or paste your own markup. CDATA sections stay intact.

Does formatting change document meaning?

No. Only whitespace, line breaks, and (on minify) optional comments change. Element names, attributes, text, and CDATA stay as written.

How is this different from the HTML minifier?

HTML is forgiving and browser-oriented. This tool validates XML-style nesting and reports line/column faults, which is what you want for config, SVG, and feed documents.

About XML Formatter & Minifier

Paste messy XML and format it for review, or minify it to a single line for embeds, logs, and payloads. This free XML formatter online and XML minifier online runs entirely in your browser, so config files, SVG markup, RSS feeds, and API envelopes with real data never leave your device. Invalid markup reports a line and column so you can fix mismatched tags fast. Same shape as the JSON and SQL minifiers: one URL, format and minify modes, indent 2 or 4, optional comments. Pair it with the HTML Minifier for markup, or the YAML to JSON Converter when you need another config format.

How to Use XML Formatter & Minifier

Choose Format XML or Minify XML. Formatting is the default.
Paste an XML document, SVG, RSS feed, or config snippet, or load a sample.
For format mode, pick 2 or 4 space indent. Toggle Keep comments on or off for either mode.
Read the element count and byte stats, then copy or download the result. Nothing is uploaded.
If the XML is invalid, the error shows the line and column of the first problem.

XML Formatter & Minifier Examples

Pretty-print a one-line feed

An RSS or Atom item squashed onto one line expands so each channel and item element sits on its own indented line for review before you commit.

Minify SVG for inline embeds

A formatted SVG becomes one compact line with comments stripped (unless you keep them). Paste the result into HTML or a React string without dragging whitespace bloat.

Fix mismatched tags

Paste broken XML with a wrong closing tag. The tool reports the mismatch at line and column so you can correct nesting before shipping a config.

Config XML with comments

Format a deployment config with Keep comments on so  notes survive. Switch to minify with comments off for a lean production blob.

Fragment snippets

Paste two sibling elements without a single root. The formatter still validates nesting and pretty-prints the fragment for clipboard use.

Common Use Cases

Pretty-print API XML responses before debugging
Minify SVG icons for inline HTML or CSS
Clean up RSS / Atom feed XML from a CMS export
Validate tag nesting in config files with line/column errors
Compress XML payloads for logs or test fixtures
