Minify XML

Every byte of XML you ship over a wire, store in an archive, or embed in a document has to be parsed, stored and transferred. Minify XML removes the whitespace and comments that bloat markup without adding meaning, producing the most compact well-formed XML possible from your input.

The tool parses the document first, so it only ever removes removable whitespace — it never trims a value that matters. A single-line result keeps attribute order and structure intact, and the declaration can be kept or dropped. You get instant size feedback, the compact output is a click away from your clipboard, and Print / Save PDF gives you an easy record of what shipped.

• Parse-based compression: whitespace is removed safely through the XML parser, never through regex guesswork.
• Optional comment stripping: remove <!-- comments --> when they are not needed in production output.
• Preserves meaning: elements, attributes, CDATA and text content are kept exactly as authored.
• Single-line output: one compact line, ideal for payloads, embeddable strings and diffs.
• Keep the declaration: choose whether <?xml …?> stays at the top.
• Size feedback: see input and output character counts to measure exactly how much you saved.
• Live updates: minify as you type or edit with the live toggle on.
• Copy, download or print: grab the result instantly or produce a PDF record.
• Round-trip friendly: the output is valid XML that any formatter can prettify again.
• Private by design: nothing leaves your browser.

1. Paste your XML or load it from a file.
2. Choose whether to strip comments — off by default so nothing is ever deleted unexpectedly.
3. Decide on the declaration — keep it for standalone files, drop it when embedding.
4. Read the size figures to confirm the reduction.
5. Copy or download the single-line result.

Example 1 — API payload optimization. A 340 KB feed of repeated records loses most of its size once indentation and comments are removed, cutting parse time and bandwidth for every client that consumes it.

Example 2 — Storing XML in a database column. Compact, comment-free XML is easier to store, index and compare in text columns than the pretty version.

Example 3 — Embedding XML in code. Minified XML is the natural size for test fixtures, build configs and serialized messages embedded in source files.

Example 4 — Clean diffs. Comparing minified versions isolates real changes instead of the whitespace churn that reformatting introduces.

• Smaller payloads — faster transfers and cheaper storage.
• Structural safety — the parser guarantees nothing meaningful is removed.
• Cleaner diffs — compare logic, not whitespace.
• Embeddable output — one line fits anywhere a string fits.
• Free and private — local processing, no accounts, no uploads.
