Max file size: 500KB | Allowed types: TXT, JSON, PDF, Images

Base64 Encoder/Decoder Guidelines

  • Enter the text or upload a file for encoding.
  • Click "Encode" to convert the input into Base64 format.
  • Paste any Base64 encoded string and click "Decode" to retrieve the original content.
  • Base64 encoding is not encryption; it is a data representation method.
  • Use this tool for debugging, API testing, and encoding data efficiently.

Base64 Encoder/Decoder Description

Base64 encoding is a binary-to-text encoding scheme used to represent binary data in an ASCII string format. It is widely used in data transmission, encryption, and storage, where text-based formats are required.

How Base64 Encoding Works

Base64 encoding transforms binary data into a readable string using a set of 64 characters: A-Z, a-z, 0-9, +, and /. Each 3 bytes of input data are converted into 4 characters of Base64.

  • Encodes any binary data into a text format.
  • Useful for embedding images, transmitting data over text protocols (like JSON, XML, and HTTP).
  • Decoding reverses the process back into the original binary format.

Example Encoding & Decoding

Encoding:

  • Input: Hello
  • Binary Representation: 01001000 01100101 01101100 01101100 01101111
  • Base64 Output: SGVsbG8=

Decoding:

  • Base64 Input: SGVsbG8=
  • Decoded Output: Hello

Common Uses of Base64 Encoding

  • Web Development: Embedding images, API communication, and URL encoding.
  • Security: Safely transmitting binary data over text-based protocols.
  • Email Attachments: SMTP email clients use Base64 to encode attachments.
  • Data Storage: Storing binary files as text in databases.

Frequently Asked Questions

Base64 encoding is a method of converting binary data into a text format using a set of 64 characters (A-Z, a-z, 0-9, +, and /).

Base64 is used to encode binary data for safe transmission over text-based systems, such as emails, web APIs, and storage formats.

No, Base64 is not encryption. It is a data encoding method that can be easily reversed.

No, Base64 is not secure for password storage. Use hashing algorithms like SHA-256 or bcrypt instead.

Simply paste the encoded Base64 string into this tool and click 'Decode' to retrieve the original text or file.
