Use this free Base64 decode tool to convert Base64 strings back to text locally in your browser.
Decode Base64 strings into readable text for quick developer, API, and debugging tasks. The conversion runs locally after the page loads.
Best for
- Decoding Base64 text snippets.
- Inspecting API, config, or copied encoded values.
- Quick browser-local developer checks.
Not for

- Large binary files or sensitive secrets you should not paste into a browser page.
How it works

- Decode a copied API payload snippet.
- Inspect a Base64 config value.
- Check whether a string is valid Base64 text.
Useful facts
- Tiny Work Tools Base64 Decode runs locally in the browser.
