Encode (component) uses encodeURIComponent — best for query values and arbitrary text (encodes / ? & too). Encode URI uses encodeURI — keeps URL delimiters; use for mostly-valid URLs with spaces or non-ASCII. Decode tries decodeURIComponent, then decodeURI.
What Is the URL Encode & Decode Tool?
The URL Encode & Decode tool converts text and links using percent-encoding, with both component-level and full-URI modes plus decoding for debugging and query construction.
Why URL Encoding Matters
Unencoded special characters can break URLs, query strings, and API requests. Correct encoding ensures links remain valid across browsers, servers, and applications.
Who Should Use This Tool?
This tool is ideal for developers, SEO specialists, marketers, QA teams, students, and anyone working with web links or parameterized URLs.
How to Encode or Decode a URL
Paste your text or URL, choose the encoding mode (component vs URI), or Decode. Use the + option when decoding typical HTML form query strings.
Proper Percent-Encoding for Special Characters
encodeURIComponent follows RFC 3986 for path/query components. encodeURI leaves / ? # and other URI delimiters unescaped so full URLs stay structured.
UTF-8 Support for International Content
JavaScript encoding uses UTF-8 percent sequences (e.g. multibyte characters become % hex pairs), suitable for international URLs and text.
Useful for Query Strings and API Testing
Encode parameter values before requests and decode responses; enable “+ as space” when mirroring application/x-www-form-urlencoded behavior.
Built-In Copy Function for Faster Workflow
One-click copy makes it easy to move results into browsers, code editors, analytics tools, and documentation without manual selection mistakes.
Best Use Cases for URL Conversion
Use it for campaign links, redirect parameters, webhook payloads, search queries, and debugging encoded values from third-party integrations.
Benefits for Reliability and Productivity
Consistent encoding/decoding reduces technical errors, improves interoperability, and speeds up day-to-day web development and optimization tasks.
