Generate a sample XML document
Choose a byte size for a small XML example with comment padding. Test your parser, then apply the XSD or business rules your application requires.
1 MB = 1,000,000 B · 1 MiB = 1,048,576 B
Advanced: test an upload limit
Enter the byte limit above, then choose one byte below, the exact limit or one byte above. Each choice uses the same base: 10,485,760 B. Generate and download each file to test your endpoint.
XML, built to spec.
Each file is a well-formed XML catalogue document. The size you ask for is reached with an XML comment node, so the result opens in browsers, Python's lxml and Java's built-in XML parser. Most people generate these for testing feed ingestion and SOAP payload limits.

These options set the generator above. Separate size guides explain how to test a particular upload boundary.
File structure and testing limits
A small XML document with a padding comment. A well-formed document still needs validation against your own XSD or application rules.
Format reference: W3C XML.
This generator assembles the file in your browser; file content is not sent to a server. Site analytics may make network requests. Office ↔ PDF conversion uses a separate server workflow. Data processing and privacy.

Questions
How small can an XML file be?
About 114 bytes. Below that the format cannot carry its mandatory structure, let alone padding.
Will the file open normally?
Validate the generated fixture in your target application. Parts added for exact size may change or disappear when the file is re-saved; compatibility depends on the reader.
Can I ask for an unusual size?
Any byte count above the minimum works — for example 3,145,728 bytes (exactly 3 MB) or 27.5 MB. Drag the caliper or type the number.
