How to use
- Paste text to encode, or a Base64 string to decode, into the box.
- Press Encode or Decode. The result and a size breakdown appear below.
- Switch to File mode to Base64-encode an image or document, up to 5MB.
- Use Copy to grab a result, or Swap to round-trip a value.
What this is for
Base64 turns binary or text data into an ASCII string that travels safely through systems built for text, like JSON payloads, data URIs, and email. Decode it to read what a token or data URI actually contains. Everything here runs in your browser, so nothing you paste is ever uploaded.
