Decode Base64 strings

How It Works

  1. Paste the Base64 string you want to decode.
  2. Click "Process" to decode it.
  3. View and copy the original text.
  4. If the result looks like garbage, the original data might have been binary (image/file).

Use Cases

  • Reading hidden data in email headers
  • Decoding API secrets or tokens during development
  • Debugging data URIs
  • Reverse engineering encoded messages

Frequently Asked Questions

Can I decode images?

This tool displays the decoded result as text. For images, use our "Base64 to Image" converter.

Is it local?

Yes, decoding happens in your browser.

What character set is used?

We assume UTF-8 encoding. Non-standard characters might look different if encoded in other charsets.
