Strict XML validation
The browser XML parser validates one well-formed document. Element order, attributes, text, comments, and CDATA content are serialized without silently repairing malformed source.
Entity-safe by design
DOCTYPE and ENTITY declarations are rejected. The tool never resolves external DTDs, loads entities, runs scripts, or requests referenced resources.
Formatting boundaries
Pretty printing adds layout whitespace between markup tokens. Minifying removes inter-tag whitespace; it does not promise schema-aware canonical XML.
Practical input limit
Input is limited to 6 MB of text. Small files, common 100 KB and 1 MB inputs, and representative 5 MB workloads are supported locally; larger work should use a streaming or command-line workflow.
