Base64 Encoder / Decoder
Encode plain text to Base64 or decode Base64 strings back to text in the browser.
When to use it
- Decode a small API payload while debugging a request or log line.
- Encode sample text for documentation, test fixtures, or quick command examples.
- Check whether a copied token-like value is encoded text before investigating further.
Examples
- Decode SGVsbG8gd29ybGQ= to confirm a fixture value.
- Encode a small JSON example before pasting it into a config field that expects Base64.
- Decode a data URI fragment to inspect what is actually embedded.
Limitations
Base64 is encoding, not encryption. Anyone can decode it. Do not treat Base64 output as a secure way to hide secrets.
