Frequently Asked Questions

URL encoding converts special characters (spaces, symbols, non-ASCII characters) to %XX format for safe URL transmission. URL decoding reverses this, restoring encoded strings to readable text.

The Essential URL Encoder/Decoder for Web Developers in 2026

URLs (Uniform Resource Locators) are restricted to a specific set of ASCII characters. When a URL contains spaces, non-ASCII characters (such as Chinese or Arabic), or special symbols like &, =, #, and %, these characters must be percent-encoded — otherwise browsers and servers cannot parse the request correctly.

In 2026, internationalized web applications are increasingly common, and URLs routinely contain non-ASCII characters. API debugging requires verifying that parameters are correctly encoded, and SEO optimization demands that Chinese URL paths are handled properly. A URL encoder/decoder belongs in every web developer's toolkit.

MeTool's URL encoder/decoder helps you quickly encode and decode URLs. Paste a URL containing special characters to see its safely encoded form, or paste an encoded URL to reveal its human-readable content — everything runs locally in your browser.

Key Features of MeTool URL Encoder/Decoder

URL Encoding

Converts special characters in URLs — spaces, Chinese characters, &, =, and more — into percent-encoded format. This ensures URLs are transmitted correctly over HTTP, and is a necessary step when constructing API requests or shareable links.

URL Decoding

Restores percent-encoded strings back to human-readable format. When you encounter a wall of %XX codes in a browser address bar or server logs, one click reveals the original content.

Multilingual Character Support

Flawlessly handles encoding and decoding of Chinese, Japanese, Korean, and other multi-byte Unicode characters. When developing internationalized applications or working with non-ASCII URL paths, you will never encounter garbled output.

API Debugging Powerhouse

When debugging RESTful APIs, you frequently need to inspect the encoding state of query parameters. MeTool lets you quickly verify whether parameters are correctly encoded, preventing request failures caused by encoding issues.
