Base64 Encoder / Decoder
Encode text to Base64 or decode it back instantly.
What is Base64 encoding?
Base64 is an encoding scheme that converts binary or text data into an ASCII string format, commonly used to embed data in URLs, JSON payloads, or email attachments. Type plain text and click Encode, or paste a Base64 string and click Decode to reverse it — both directions run entirely in your browser.
A working example is already filled in below — click Encode to see how it turns into Base64, then click Decode on the result to get the original text back.
