About Base64 Tools
Base64 Tools encode and decode data using Base64, a text representation of binary data. Convert plain text or files into a Base64 string, or decode a Base64 string back to its original form. This is essential for embedding images in CSS or HTML (data URIs), transmitting binary data over text-based protocols, and debugging API payloads.
Encoding and decoding run entirely in your browser, so files and secrets you process are never uploaded.
How to use Base64 Tools
- Paste text or upload a file.
- Choose Encode or Decode.
- Read the converted output.
- Copy or download the result.
