Text Encoder & Decoder
Instantly convert strings to Base64, URL Encoded, HTML Entities, Binary, or Hex formats.
About the Text Encoder & Decoder
Whether you are debugging a broken URL, inspecting a Base64-encoded API token, or preventing XSS injection by encoding HTML entities, the OnlinePaste.com Encoder Tool provides an all-in-one developer workspace to instantly convert strings between different computer formats.
Supported Formats
- Base64: Safely encodes binary data to ASCII format. Fully supports UTF-8 characters and emojis.
- URL Encoding: Escapes special characters for safe transmission over HTTP (percent-encoding).
- HTML Entities: Converts characters like
<and>to<and>to prevent code execution. - Binary & Hex: Translates human-readable text into raw machine formats.
100% Client-Side Processing
Because decoding strings often involves sensitive information (like JWT tokens, passwords, or proprietary API requests), we built this tool to prioritize your privacy. The entire conversion engine runs directly inside your web browser via JavaScript. Your strings are never uploaded, saved, or transmitted to our servers.
