Convert XML to Base64

XML is full of characters that transport layers mangle: angle brackets, quotes, ampersands. Convert XML to Base64 encodes your document into a portable, universally safe text form — the standard way to carry XML inside emails, JSON payloads, URLs and databases.

The document is first converted to UTF-8 bytes, so non-Latin text and symbols survive the round-trip exactly. Output can be wrapped at 76 characters for MIME compatibility or prefixed as a data URL for direct browser use. Encoding happens locally; your XML never leaves your machine.

• Standard Base64 output — universally decodable, with correct padding.
• UTF-8 safe: international text and symbols are encoded byte-exactly.
• MIME line wrapping: wrap at 76 characters for older transport systems.
• Data URL prefix: emit data:application/xml;base64, for direct browser use.
• Instant stats: see the size difference between source and encoding.
• Live updates: re-encode as you type with the live toggle.
• Copy, download or print: the Base64 is a click from your clipboard.
• Round-trip friendly: decode with the companion tool to verify fidelity.
• Private by design: encoding happens locally, nothing uploaded.

1. Paste your XML or load it from a file.
2. Enable line wrapping if the output is destined for MIME-style transport.
3. Enable the data URL prefix if you want to embed the payload directly.
4. Copy or download the Base64 output.

Example 1 — Embedding in JSON. An API that accepts XML but speaks JSON can receive the XML as a base64-encoded string field, avoiding all escaping problems.

Example 2 — Email attachments. MIME email bodies and inline XML snippets are routinely carried in base64 to survive quoting and line-length rules.

Example 3 — Database storage. Storing XML in a text column as base64 sidesteps encoding and delimiter collisions in legacy systems.

Example 4 — URL transport. Base64 (URL-safe when needed) lets XML ride inside a single parameter without angle brackets breaking the request.

• Transport-safe — no angle brackets or quotes to mangle.
• Byte-exact — UTF-8 encoding preserves every character.
• Universal — standard Base64 decodes anywhere.
• MIME and data-URL ready — both formats one click away.
• Free and private — local encoding, no uploads.
