Base64 To Text

Decode a Base64 string back into its original, readable text or binary data.

Our Base64 to Text decoder reverses the Base64 encoding process, converting the string back into its original text. Essential for decoding data from web sources, API responses, or encrypted messages. Decode Base64 to text instantly!

Use URL-safe Base64 (- and _ instead of + and /)

Tip: Try encoding text with special characters like "???" or "3.14159" to see the difference between standard (+/) and URL-safe (-_) encoding.

FAQ

Common questions 3 questions

What happens if the Base64 string is invalid?

If the string contains characters outside the Base64 alphabet or has incorrect padding (`=`), the decoding process will likely fail or produce garbled output.

Can this decode an image's Base64 string?

Yes, if the Base64 string represents an image, the tool will decode it back to the original binary image data, which you may need to save as a file (e.g., JPG, PNG).

Where would I find a Base64 string to decode?

In API responses, data URI schemes in CSS/HTML, OAuth tokens, or email headers where binary data was transferred safely.
