How to use Base64 Converter

Encode text or small payloads to Base64 — and reverse it — without a CLI.

  1. Paste plain text or Base64 string.

  2. Choose encode or decode direction.

  3. Copy the output for headers, data URIs, or config files.

Common questions

Does it handle Unicode?

Text is encoded via standard UTF-8 → Base64. Emoji and non-Latin scripts are supported.

Is Base64 encryption?

No. It is encoding only — anyone can decode it. Never treat it as security.

File uploads?

Designed for text in the browser. Large binary files may be impractical in-tab.
