Text Encoder / Decoder
Encode or decode text with Base64, URL encoding, HTML entities, hex, binary, and more. All processing happens in your browser – no data is ever uploaded.
How to Use the Text Encoder / Decoder
Our tool makes encoding and decoding text simple and fast. Follow these steps:
- Enter your text – Paste or type the content you want to encode or decode into the main text area.
- Choose an operation – Select the desired encoding or decoding method from the dropdown menu (Base64, URL, HTML entities, Hex, or Binary).
- Click "Encode / Decode" – The result appears instantly in the output area below.
- Copy or download – Use the "Copy Text" button or "Download .txt" to save the result.
What Each Operation Does
| Operation | Description | Example |
|---|---|---|
| Base64 Encode | Converts text to Base64 (used for email attachments, APIs) | Hello → SGVsbG8= |
| Base64 Decode | Converts Base64 back to plain text | SGVsbG8= → Hello |
| URL Encode | Escapes special characters for use in URLs | Hello World! → Hello%20World%21 |
| URL Decode | Restores original text from URL‑encoded string | Hello%20World%21 → Hello World! |
| HTML Entities Encode | Converts characters like < and > to HTML entities | |
| HTML Entities Decode | Converts HTML entities back to characters | <div> → |
| Hex Encode | Converts text to hexadecimal representation | Hello → 48 65 6c 6c 6f |
| Hex Decode | Converts hex back to text | 48 65 6c 6c 6f → Hello |
| Binary Encode | Converts text to binary (8‑bit binary per character) | A → 01000001 |
| Binary Decode | Converts binary back to text | 01000001 → A |
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
Is this tool really free?
Yes, completely free with no limits. No login or payment required.
Can I use this for large files?
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.
Does it work on mobile?
Absolutely! The page is fully responsive and works on iPhones, Android devices, and tablets.
Is my text private?
100% private. All encoding and decoding happens inside your browser – no data leaves your device.
What if I get an error while decoding?
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.
