Encode or decode URLs instantly.
URL encoding, also known as percent-encoding, is a method used to convert characters in a URL into a format that can be safely transmitted over the internet. Certain characters, such as spaces, ampersands, question marks, and other special symbols, have specific meanings within a URL structure and can cause errors or unexpected behavior if used directly. Our URL Encoder / Decoder tool allows you to instantly convert regular text into a properly encoded URL format, or decode an already encoded URL back into readable, human-friendly text.
This tool is commonly used by developers, digital marketers, and SEO professionals who work with query parameters, tracking links, API requests, or dynamically generated URLs. For example, when building a URL that includes a search query with spaces or special characters, those characters need to be encoded so that browsers and servers interpret the URL correctly. Similarly, when working with UTM tracking parameters for marketing campaigns or debugging API responses, being able to quickly decode a URL back into its readable form makes it much easier to understand what data is actually being passed.
Manually encoding or decoding URLs by hand is time-consuming and prone to errors, especially with longer URLs containing multiple special characters or non-English text. This tool handles the conversion instantly and accurately, following standard percent-encoding rules, so you can copy and paste the result directly into your code, browser, or application without worrying about malformed URLs breaking your links or requests.
Whether you're troubleshooting a broken link, preparing a URL for use in an HTML form, working with REST APIs, or simply trying to understand what a long, encoded URL actually says, our URL Encoder / Decoder provides a fast and reliable way to convert between these two formats in either direction.
URL encoding converts special characters, spaces, and non-ASCII characters into a format that can be safely included in a URL, ensuring the link works correctly across browsers and servers.
Those percent-encoded sequences, such as %20 for a space, represent characters that cannot be included directly in a URL. Decoding them reveals the original, readable text.

Properly encoded URLs help ensure that search engines and browsers can correctly interpret and index your pages, especially when URLs include query parameters or special characters, which can otherwise cause crawling or indexing issues.
