What is the Text Encoding Tool?
Web developers constantly face encoding issues — HTML injection, URL parameters breaking, or Base64 image strings. Our tool provides a unified interface to convert text between 12+ encoding standards instantly.
Stop debugging corrupted characters. Encode for safe output, decode for debugging, and copy results in one click — all in your browser, no data leaves your device.
🔐 HTML Entity🌐 URL Encoding📦 Base64🈴 Unicode
💻For Web Developers
Escape user input, encode API parameters, decode debug logs.
🛡️For Security Analysts
Test XSS payloads and analyze encoded attack vectors.
Every encoding you need in one dashboard
Convert between HTML, URL, Base64, Unicode, Hex, and more.
HTML Entity Encoder/Decoder
Converts special characters like < > & " to safe HTML entities and back.
→ Why matters: Prevent XSS attacks and display code snippets safely.
URL Encoding (Percent)
Encodes special characters for safe URL transmission per RFC 3986.
→ Why matters: Fix broken links and API query parameters.
Base64 Encode/Decode
Convert text to Base64 string and back — perfect for images, tokens, and data URIs.
→ Why matters: Embed assets in CSS/HTML, decode JWT tokens.
Unicode Escape / Unescape
Converts between raw Unicode and uXXXX escaped format.
→ Why matters: Debug internationalization and JSON Unicode sequences.
Hex & Binary Converter
Convert text to hexadecimal or binary representation.
→ Why matters: Analyze raw data, reverse engineer protocols.
Copy & Paste Integration
One-click copy buttons for every encoded output field.
→ Why matters: Seamless workflow — encode, copy, paste into code.

Common questions about text encoding
Does this tool send my data to a server?+No. All encoding and decoding happens entirely in your browser using JavaScript. Your text never leaves your device — perfect for sensitive API keys, passwords, or proprietary code.What encoding standards are supported?+We support HTML entities (named & numeric), URL percent encoding (RFC 3986), Base64 (UTF-8), Unicode escapes (uXXXX), hexadecimal, binary, and ASCII/ISO encodings.Can I encode very long text strings?+Yes — up to 50KB per conversion. For extremely large files, we recommend splitting into smaller chunks, but most use cases work perfectly.How do I know which encoding to use?+HTML encoding for safe web display, URL encoding for query strings, Base64 for email attachments/data URIs, Unicode for international text in JSON, Hex for debugging binary data.Does it handle emoji and special characters?+Absolutely. All encoders fully support UTF-8, including emojis, accented characters, and CJK symbols. Unicode escapes will convert them to uXXXX sequences.Is there an API for developers?+We’re planning a free public API. For now, you can use the client-side tool or bookmark the page for quick access.Can I decode Base64 that contains binary data?+Yes, but binary data may not display as readable text. Our tool shows the raw decoded bytes and offers a hex view for non-text payloads.How is this different from browser devtools?+DevTools require manual encoding using btoa()/encodeURIComponent(). Our tool provides a visual interface with copy buttons and supports 12+ formats in one place.
