Free Base64 to Text Decoder
Convert a Base64-encoded string back into readable text instantly, with full UTF-8 support. Everything runs privately in your browser.
What is Base64 to Text decoding?
Decoding reverses Base64 encoding, turning that string of letters and numbers back into the original human-readable text. It's handy when you receive Base64 data in an API response, a JWT payload, a config file, or an email header and need to read what it actually contains.
Paste the encoded string above and the decoded text appears immediately. The decoder handles UTF-8, so international characters and emoji are restored exactly, and everything is processed locally in your browser.
Frequently asked questions
How do I decode a Base64 string?
Paste your Base64-encoded string into the box and click Decode. The original text appears instantly, decoded as UTF-8 so special characters and emoji come through correctly.
Why do I get an error when decoding?
That usually means the input isn't valid Base64 — it may be truncated, contain invalid characters, or have been altered. Double-check you copied the full, unmodified string.
Is decoding done privately?
Yes. All decoding happens in your browser; nothing is uploaded or stored.
