Base64 Encoder Online
Encode text, including accented characters and emoji, as Base64. The tool converts your text to UTF-8 bytes before applying the standard Base64 alphabet.
- Encode Unicode text through UTF-8
- Produce standard Base64 with padding
- Copy the encoded text for integration
Encode a text value
Paste the original text and run the encoder. Newlines and spaces are included, so remove accidental whitespace before encoding.
Keep international characters intact
UTF-8 represents characters using bytes before Base64 encoding. Decode the result as UTF-8 to recover the same text.
Use Base64 for transport
Base64 expresses binary bytes using printable characters. It usually makes data larger; it is not a compression method.
Do not confuse encoding with secrecy
Anyone with the encoded string can decode it. Never rely on Base64 to hide passwords or confidential information.
Base64 Encoder FAQs
No. It returns encoded text without a media-type prefix. Use Image to Base64 for an image data URI.
No. Output uses standard Base64; URL-safe encoding uses different characters for plus and slash.
The text Hello, with no extra space or newline, encodes to SGVsbG8=. Adding a line break changes the bytes and therefore the output. This encoder handles UTF-8 text and returns standard Base64, not a media-prefixed data URI.
