Randomly
Base64 Encoder
Quickly convert plain text into Base64 format directly in your browser.
Input
Base64 · encoded
EncodedType text in the input panel to encode it.
Base64 maps every 3 bytes onto 4 ASCII characters so binary data survives text-only channels — data URIs, JSON, email. It's an encoding, not encryption: anyone can reverse it. This tool round-trips full UTF-8, so accented and non-Latin text encode and decode cleanly.
Base64 encoding is widely used in web development, APIs, email systems, and data transfer workflows. Our Base64 Encoder helps you quickly convert plain text into Base64 format directly in your browser.
Base64 is commonly used to safely represent text or binary data in ASCII string format, especially when transferring data across systems that may not handle raw binary input well. Developers, testers, and technical users often use Base64 encoding in JSON payloads, authentication, APIs, and file-related workflows.
This tool is fast, browser-based, and requires no sign-up or installation.
What is Base64 encoding?
Base64 Encoding is a method used to convert text or binary data into a readable ASCII string format using letters, numbers, and symbols. It is commonly useful for:
- API payloads
- Email encoding
- Data transfer
- JSON and web development
- File handling
- Authentication workflows
How to use the Base64 Encoder
