About Base64 encoding and decoding
Base64 encoding turns text or binary data into a plain-ASCII string that can travel safely through systems built only for text, such as email and JSON. This tool encodes and decodes Base64 instantly, both directions, in your browser.
Tips
- Base64 is encoding, not encryption — anyone can decode it.
- Encoded data is about a third larger than the original.
- Use it to embed small files in HTML, CSS or JSON.
