Encode/decode text using common web-safe formats.
Encode and decode text between Base64, URL, and HTML entity formats instantly. This free browser-based utility handles common web encoding transformations without sending any data to a server. Perfect for developers, content creators, and anyone working with web-safe text formats.
The Encoder and Decoder is a text transformation tool that converts content between its original form and various encoded formats commonly used in web development. Base64 encoding converts binary or text data into an ASCII string safe for transport in URLs and emails. URL encoding replaces unsafe characters with percent-encoded equivalents for use in query strings and links. HTML entity encoding converts special characters like angle brackets and ampersands into their entity equivalents to prevent rendering issues or cross-site scripting vulnerabilities. All processing happens directly in your browser with zero server round-trips.
Select your desired encoding format from the dropdown — Base64, URL Encode, or HTML Entities. Paste or type your text into the Input field. Click "Encode" to convert plain text into the selected format, or click "Decode" to reverse an encoded string back to readable text. The result appears instantly in the Output field. Use "Copy Output" to grab the transformed text for use in your project, email, or API request.
