URL Encoder & Decoder – Encode URLs & Decode Safe URLs Online | OnlineUtilityTools

Encode or decode URLs instantly using our easy online URL encoder tool.

URL Encoder – Encode URLs and Text Online

URL encoding converts special characters in URLs into a safe format that browsers and servers understand. When building web applications, handling URLs with spaces, accents, or symbols requires encoding them as percent-encoded sequences. Developers use URL encoding for query parameters, form data, and API requests. Our online URL encoder/decoder makes this conversion instant and effortless—no command-line tools or programming required.

When Should You Use This Tool?

Query Parameters:Encode search terms, filters, and values in URL query strings safely.
Form Submissions:Properly format form data with special characters for HTTP requests.
API Requests:Encode parameters in REST API calls and webhook payloads.
Link Debugging:Decode complex URLs to see the original values and troubleshoot broken links.

Example of How This Tool Works

Input (Plain Text):

Hello World & Special $Chars

↓ Encode ↓

Output (URL Encoded):

Hello%20World%20%26%20Special%20%24Chars

Spaces become %20, ampersands become %26, and special characters are converted to their percent-encoded equivalents for safe transmission in URLs.

URL Encoding Essentials

URL encoding is critical for web development, converting special characters into safe ASCII format for transmission. Spaces become %20, ampersands become %26, and other special characters follow percent-encoding standards. This ensures URLs work correctly across browsers, servers, and APIs without interpretation errors. Our URL encoder/decoder handles all encoding scenarios instantly.

URL encoding use cases: Building dynamic URLs with query parameters, submitting form data safely, creating API requests with special characters, embedding URLs in HTML or JavaScript, and debugging malformed URLs. Developers, marketers, and system administrators use URL encoding daily for data transmission and link generation.

Instantly encode text or URLs to safe format, or decode encoded URLs back to readable text. Our tool handles all characters and Unicode properly, perfect for developers building web applications, APIs, and data processing systems. Fast, accurate, and completely free.
