Encode XML to Base64 Online
SOAP and SAML messages, document exports, and SVG images are often transported as Base64-encoded XML. This encoder checks that your XML is well-formed and then converts it to standard Base64 or URL-safe base64url.
Features
Validates first
Your XML is checked for well-formedness before encoding, with exact line and column errors.
Minify before encoding
Encode exactly as typed, minified to save space, or pretty-printed.
Full UTF-8 support
Non-ASCII characters are encoded correctly as UTF-8, unlike the browser's btoa().
SVG data URIs
Encode SVG images to embed them in CSS or HTML as data:image/svg+xml;base64 URIs.
base64url and MIME
Use the URL-safe alphabet, or wrap lines at 76 characters for email and MIME.
Private by design
Encoding runs entirely in your browser. Your data is never uploaded.

- Paste your XML into the input editor, or upload an .xml or .svg file.
- Choose whether to encode it as typed, minified, or pretty-printed.
- Enable URL-safe or line wrapping if you need them.
- Copy the Base64 output or download it as a text file.
Frequently Asked Questions
Why encode XML as Base64?
Base64 lets you safely embed XML inside other formats: SOAP attachments, JSON fields, SAML messages, email (MIME), and data URIs. It avoids problems with quotes, angle brackets, and line breaks.
How do I use an SVG as a data URI?
Paste the SVG markup, copy the Base64 output, and prefix it with data:image/svg+xml;base64, for use in CSS background-image or an img src attribute.
Should I minify XML before encoding?
Minifying removes whitespace between elements, which makes the Base64 output shorter. Choose As typed if the exact original text matters, for example for signed XML.
Is my XML uploaded anywhere?
No. Encoding runs entirely in your browser. Your XML never leaves your device.
