Acerca de Base64
Base64 is a binary-to-text encoding that represents bytes using only ASCII characters. It is widely used for email attachments, embedding images in JSON or CSS, HTTP Basic auth, and any channel that accepts text only.
toco.tools’s Base64 tool encodes plain text to Base64 and decodes Base64 back to text, with UTF-8 support for multilingual content. Copy results in one click for quick debugging and prototyping.
Base64 is not encryption—encoded data is easily reversed. Avoid treating it as secrecy. Very large inputs may hit browser memory limits; split huge files if needed.
Cómo usarla
- Paste text into the input
- Choose encode or decode
- Copy the result
Preguntas frecuentes
What is Base64?
An encoding that represents binary data as ASCII text, common in email, JSON, and URLs.
Does it support Japanese and emoji?
Yes. Text is handled as UTF-8, so multibyte characters encode and decode correctly.
Is uploaded data sent externally?
No. All processing runs in your browser; nothing is sent to toco.tools servers.
Is Base64 encryption?
No. Anyone can decode it; do not use it to protect secrets.
