Minify a valid XML document

For shrinking a document before transfer or integration without changing its structure, XML minifier creates a compact version.

Shrink valid XML by stripping unnecessary whitespace and receive a compact version for transfer or storage. No upload or storage is involved.

How to use

Paste the valid XML into the input area or import the file you need to shrink.
Run minification to remove unnecessary spaces and line breaks.
Copy the compact result for transfer, storage or integration.
Check with a validation tool that the XML is still accepted.

Example

A team needs to send an XML configuration file to an external service. They paste the indented document, run minification and get a more compact version. Before sending it, they validate the result to make sure the structure has not been altered.

Limits and formats

Minification should only be applied to valid XML, otherwise existing errors remain.
Removing spaces can change meaning in rare cases where whitespace is intentionally significant.
The compact result is harder to read during human review.
The tool does not create an archive and does not reduce the data itself.

Where processing happens

Everything runs in your browser: unnecessary spaces are removed locally from the XML document. The file or text you paste is never uploaded, shared or stored.

Frequently asked questions

Does minification really reduce file size?

It removes unnecessary spaces, tabs and line breaks, which generally reduces the number of characters. The gain depends on the original indentation and the content, so check the size before transferring the file.

Can I minify XML that contains important spaces?

If your document uses significant spaces in values or text nodes, minification may change them. Test on a copy and compare how your application behaves before replacing the original file.

Will a machine still read the minified XML?

Yes, well-formed XML remains usable by parsers after unnecessary spaces are removed. It is simply harder for humans to read, so keep an indented version for maintenance and future corrections.
