🔄 Encoders & Decoders

Professional encoding and decoding utilities for web developers, supporting Base64, URL encoding, HTML entities, and Quoted-Printable formats.

Why Encoding Tools Matter

When working with websites, APIs, or email systems, data often needs to be converted between different formats to display correctly or transmit safely. Incorrect encoding can break web forms, cause display issues, or create security vulnerabilities.

These encoding tools handle the most common conversion tasks that come up in daily digital work. Whether you're preparing data for API calls, embedding content in HTML, or ensuring text displays properly across different platforms, these utilities make format conversion quick and reliable.

What You Can Do Here

Unlike traditional online tools that upload your data to remote servers, everything here processes locally in your browser. This approach is faster, more private, and eliminates security concerns about sensitive information like API keys, passwords, or proprietary code leaving your device.

URL Encoding: Safely encode URLs and query parameters for REST APIs and form submissions.

Base64 Conversion: Convert text and binary data for email attachments, data URLs, and API tokens.

HTML Entities: Safely encode special characters to prevent XSS attacks and display reserved characters.

Email Formatting: Encode text for MIME email transmission ensuring proper display across email clients.

Privacy & Processing

All encoding and decoding happens locally in your browser using standard JavaScript functions. The tools never send your data anywhere - everything processes on your device, making these utilities safe for handling sensitive information like authentication tokens or confidential content.

Frequently Asked Questions

Is any data sent to your server?

No. All encoding and decoding happens locally in your browser using JavaScript. Your text and files never leave your device.

What is Base64 encoding used for?

Base64 converts binary data to text format for email attachments, data URLs in web pages, API tokens, and embedding images directly in CSS or HTML code.

When should I use URL encoding?

Use URL encoding when passing data in web addresses, form submissions, or API calls. It safely converts special characters like spaces, ampersands, and symbols to percent-encoded format.

Why encode HTML entities?

HTML entity encoding prevents XSS attacks and ensures special characters like <, >, and quotes display correctly in web pages instead of being interpreted as HTML code.

What is Quoted-Printable encoding?

Quoted-Printable is an encoding method for email transmission that ensures 8-bit characters and special symbols display correctly across different email clients and systems.

Common Use Cases

  • API Integration: Encode request parameters and decode server responses
  • Web Development: Safely display user input and embed data in HTML
  • Email Systems: Format content for proper display across email clients
  • Data URLs: Embed images and files directly in CSS or JavaScript
