  4. Copy or download – Use the "Copy Text" button or "Download .txt" to save the result.

What Each Operation Does

OperationDescriptionExample
Base64 EncodeConverts text to Base64 (used for email attachments, APIs)HelloSGVsbG8=
Base64 DecodeConverts Base64 back to plain textSGVsbG8=Hello
URL EncodeEscapes special characters for use in URLsHello World!Hello%20World%21
URL DecodeRestores original text from URL‑encoded stringHello%20World%21Hello World!
HTML Entities EncodeConverts characters like < and > to HTML entities
&lt;div&gt;

Hex EncodeConverts text to hexadecimal representationHello48 65 6c 6c 6f
Hex DecodeConverts hex back to text48 65 6c 6c 6fHello
Binary EncodeConverts text to binary (8‑bit binary per character)A01000001
Binary DecodeConverts binary back to text01000001A

Common Use Cases

  • Web Development: Encode strings for safe URL parameters (URL encode), store binary data in JSON (Base64), or escape HTML when displaying user input (HTML entities).
  • Debugging: Decode encoded tokens, headers, or API responses to read plain text.
  • Educational: Learn how characters map to hexadecimal and binary representations.
  • Email & Data Transmission: Use Base64 to embed images or attachments in text formats.

Pro Tip: All operations are performed locally in your browser. Your text is never sent to any server – complete privacy guaranteed.

Frequently Asked Questions

Yes, completely free with no limits. No login or payment required.
The tool works well with large amounts of text, but extremely large files might cause slowdown in your browser. For best results, process chunks of up to a few megabytes.
Absolutely! The page is fully responsive and works on iPhones, Android devices, and tablets.
100% private. All encoding and decoding happens inside your browser – no data leaves your device.
Make sure your input matches the selected operation. For example, Base64 decode expects a valid Base64 string. Invalid input will show an alert – just double-check and try again.
