How to encode text to Base64

1. Paste the source text

   Put plain text into the "Text" field. Any characters are accepted — emoji, non-Latin scripts, control characters. The tool treats it as UTF-8.

2. How the encode works

   Internally: `Buffer.from(text, 'utf8').toString('base64')`. The output uses the standard Base64 alphabet (A–Z a–z 0–9 + / =) with padding, not URL-safe.

3. Press Run

   Output is a single `base64` field — the encoded string. There are no options for line wrapping, MIME spacing, or URL-safe substitution.

4. Use it where Base64 is expected

   Common targets: `data:` URLs, HTTP Basic auth headers, JSON-embedded binary, mail attachments. If the receiver wants URL-safe encoding, replace + with - and / with _ after copying.
