How to Use the File Encoding Converter

This File Encoding Converter allows you to convert text between popular encoding formats such as UTF-8, UTF-16, Base64, ASCII, and Binary. The conversion is processed entirely in your browser, ensuring privacy and fast performance with no data uploaded to any server.

1. Enter or Paste Your Text

Start by typing or pasting your text into the input box. The tool will automatically detect the input format, such as:

  • ASCII – Basic English characters only
  • Base64 – Encoded strings commonly used for data transfer
  • Binary – 0/1 sequences
  • UTF-8 – Most Unicode text including emoji

If the detection is incorrect, you may manually select the input type.

2. Choose Output Encoding

Select the format that you want to convert into. Supported formats:

  • UTF-8 – Standard encoding for most modern text
  • UTF-16 – Used by Windows systems and certain APIs
  • Base64 – Encoded text safe for storage or transfer
  • ASCII – Basic 7-bit characters only
  • Binary – 8-bit binary representation

3. Convert

Click Convert to immediately process your input. The converted text will appear in the output box below.

4. Copy Result

Click Copy to save the converted text to your clipboard. This is helpful when transferring encoded values into applications or code.

Troubleshooting & Notes

  • Invalid Base64 input will cause an error — ensure padding is correct.
  • Binary input must be separated by spaces, e.g., 01000001 01000010.
  • ASCII output replaces any unsupported character with ?.
  • UTF-16 output uses JavaScript's internal UCS-2 representation.

This tool is ideal for developers, data engineers, security testing, encoding troubleshooting, or converting data between systems.
