Base64 Encode / Decode

How to Use Base64 Encode / Decode

2. Click Encode to Base64 to convert plain text into Base64, or Decode from Base64 to convert it back.
3. Click Copy Output to copy the result to your clipboard.

How It Works

Base64 is a way of representing text or binary data using only readable characters — commonly used in emails, data URLs, and API payloads. This tool uses your browser's built-in encoding functions, so your text never leaves your device.

Frequently Asked Questions

Is Base64 encryption? No — Base64 is not encryption or a security measure; it's simply a reversible text encoding. Anyone can decode it, so don't use it to protect sensitive information.

Why do I get a decode error? This usually means the input isn't valid Base64 — check for missing characters or extra spaces.
