How it's rendered
Native DOMParser. Parsed with the browser's built-in XML parser; rendered as a collapsible element tree.
Nothing about this file is ever sent to a server — open your browser's DevTools Network tab while using this viewer and you'll see no request carrying your file's contents.
100% Private
Files never leave your device. There is no server that ever receives your file's contents.
No Uploads
Every format is decoded and rendered locally via WebAssembly or JavaScript. Open your browser's Network tab and confirm nothing is sent.
No Storage
Nothing is written to a server or database. Memory clears the moment you close or reload the tab.
GDPR-friendly by design
There's no file data collection to comply with in the first place — no account, no tracking of file contents, no analytics on what you view.
XML viewer — FAQ
Will it tell me if my XML is invalid?
Yes — invalid XML is flagged immediately using the browser's own XML parser error message.
Can it handle large XML files?
Yes, though extremely large files are bounded by your device's memory.
Is the file uploaded anywhere?
No, parsing happens entirely client-side using the browser's native DOMParser.
Does it show attributes?
Yes, each element's attributes are shown inline in both the tree and raw views.
Can I copy the XML?
Yes, use the Copy button to copy the raw file contents.
