Encode plain text to Base64 format or decode Base64 strings back into readable text instantly.
Text-to-binary data encoding utilities
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It translates bytes into a character set of 64 characters (A-Z, a-z, 0-9, +, /) to ensure safe transfer over text-based protocols.
Base64 is commonly used to embed binary data (like images or fonts) directly into HTML, CSS, or JSON documents. It ensures that data remains intact without corruption when passing through systems that only support text-based transport.
No. Base64 is an encoding method used for formatting data, not for securing it. Anyone can easily decode a Base64 string back to its original form. For security, you must use proper encryption algorithms like AES.
Yes. Base64 encoding increases the data size by approximately 33% compared to raw binary data. While convenient for small assets, it is generally inefficient for transferring very large files.
