What is Base64?

Base64 represents binary data (bytes) using only 64 safe characters: A-Z, a-z, 0-9, +, /, = for padding. It is perfect for sending data through systems that explain plain text (emails, JSON, form fields).

How to use the Base64 converter calculator

Step by step:

  • Choose an operation from “Encode to Base64” or “Decode from Base64”.
  • Enter Text input.
  • After entering the values, click on calculate, and in seconds, you will see the result.

Example 1: If we choose to encode to Base64 4

Enter “HelloWorld!” in the input text box.

Step by step:

  • Step 1: Encoding text to Base64
  • Step 2: Original text: "HelloWorld!"
  • Step 3: Original length: 11 characters
  • Step 4: Base64 encoded: SGVsbG9Xb3JsZCE=
  • Step 5: Encoded length: 16 characters
  • Step 6: Size increase: 45.5%

result:

  • Encoded text: SGVsbG9Xb3JsZCE=,
  • Original length: 11,
  • Encoded length: 16

Example 2: If we choose to decode from Base64

Step by step:

  • Step 1: Decoding Base64 to text
  • Step 2: Base64 input: "U2F2ZSB0aW1lLCBzaGFyZSBtb3JlIQ=="
  • Step 3: Input length: 32 characters
  • Step 4: Decoded text: "Save time, share more!"
  • Step 5: Decoded length: 22 characters

result:

  • Decoded text: Save time, Share more!
  • Original length: 32,
  • Decoded length: 22,

User-Friendly

This calculator allows for the parallel encryption and decoding of data. This tool is exceptional for the purpose of incorporating text snippets into query parameters, JSON, HTML, or CSS. It has a simple and clear interface. Anyone can use it easily.

Step by step:

  • Trailing = or == is normal; do not remove it while decoding.
  • Before decoding Base64, remove any unexpected spaces or line breaks.
  • Always double-check your input.

FAQ

Why does my output conclude with the symbol "="?

= is padding so the output length is a multiple of 4. That’s expected.

Is it possible to decode improperly formatted Base64 data?

The converter checks the input. If characters or padding are invalid, the calculator will display an error, allowing you to correct the input.
