XML Prettifier & Compressor — Clean & Fast
Working with XML configuration, APIs, or data exports often requires two states: human-readable for debugging and editing, and minified for transmission or storage. The OnlinePaste.com XML Toolkit provides both operations using a native DOM parser — no server upload required, and your data never leaves your browser.
Smart Pretty Printer
Automatically detect node hierarchy and produce perfectly indented XML. Choose between spaces or tabs, and optionally strip comments for cleaner display. Even complex documents with attributes, CDATA, and mixed content retain their original structure.
Aggressive Minification
Remove unnecessary whitespace, strip comments, and compress all text nodes for the smallest possible payload. Ideal for API responses, production config files, and reducing bandwidth usage. The built-in validator ensures well-formed XML before processing.
