Base64 Encoder

This tool converts any text into Base64 format instantly. It’s perfect for encoding binary data, safely embedding text in URLs or HTML, or converting readable input into a format that’s more suitable for transmission or storage. You can paste or import a file, tweak the encoding behavior using toggles, and get the Base64 output live with no reloading or delays.

Paste your input above or import a file below.

Use UTF-8 encoding

How to Use:

  1. Paste your input into the left text box – any text, code, or content you want to encode.
  2. Or click Choose File to upload a plain-text format like .txt, .html, .json, or .csv.
  3. Use the toggles under Options:
    • Trim input before encoding: Strips extra whitespace before converting.
    • Break into 76-char lines: Splits the Base64 output into MIME-style chunks.
    • Use UTF-8 encoding: Ensures multi-byte characters are handled correctly.
  4. The right-hand output updates automatically as you type or load input.
  5. Click Copy Output or Export to File to save your result.
  6. Use Clear All to reset everything quickly.

What the Base64 Encoder Tool can do:

It encodes any string into Base64, turning normal characters into ASCII-safe sequences that can be used in email bodies, embedded resources, JSON blobs, and more. You can toggle how it processes input, whether it breaks long lines, and whether it encodes using UTF-8. The tool provides instant results, output size tracking, and supports copy/export functionality right in your browser.

Example:

Input:

Hello World!

Output:

SGVsbG8gV29ybGQh

Common Use Cases:

Use this when you need to safely encode text for transport across systems that don’t handle raw characters well. Base64 is ideal for embedding images or text in HTML, generating email attachments, or storing blobs in a readable form. This tool simplifies the process and ensures the result is accurate and ready to use.

Useful Tools & Suggestions:

If you’re prepping content for transfer or storage, Base64 Decoder helps you quickly verify or recover the original data. And for more specialized needs, Convert Unicode to Base64 lets you handle multi-language or emoji-heavy text while preserving full character integrity.
