URL Encode / Decode

Encode or decode URL strings instantly by pasting text into the input field.
This tool supports percent-encoding commonly used in URLs, making it easy to convert special characters into a safe format
or restore encoded strings back to readable text.

It is useful for building query parameters, checking API request URLs, and debugging encoded values found in logs or configuration files.
With a single click, you can switch between encoding and decoding
and view the result immediately.

All processing is performed locally in your browser.
No input text or results are sent to any server, ensuring fast performance and privacy-safe usage.

Guide: How to use & features

  • Enter text at the top and click Encode or Decode to transform it.
  • Review how spaces and special characters change, then copy the output for reuse.
  • Long query strings are supported; very large inputs may take a moment to process.
  • All conversions run locally with no network requests.

Samples: Sample input & output

FAQ: Frequently asked questions

  • What gets encoded?

    Reserved characters, spaces, and non-ASCII text are percent-encoded so you can drop the result directly into URLs.
  • Is it okay to include line breaks or non-Latin text?

    Yes. Only the necessary characters are encoded and reflected in the output.
  • What if decode fails?

    Malformed sequences can trigger errors. Check any % sequences and try again.

Use cases: Common use cases

  • Encoding query parameters

    Verify URL encoding so values with spaces or symbols can be embedded safely.

  • Decoding to inspect payloads

    Decode long query strings to understand their meaning and spot unintended values.

  • Supporting webhook tests

    Encode or decode signed query parts to isolate verification errors.

Notes: Notes & limitations

  • Work stays in your browser

    Inputs and outputs remain local. Closing the tab or clearing cache will remove any temporary state.

  • Validate critical data

    Results are helper outputs—double-check them before sending to production systems or sharing externally.

  • Large payloads depend on your device

    Very large text or files can feel slow in some browsers. Use a desktop environment for heavy workloads.

URL Encoder and Decoder

URLs often need special characters, spaces, non-English text, and symbols to be percent-encoded. This URL encoder and decoder helps you convert readable text into URL-safe strings and decode encoded values such as %20, %2F, or UTF-8 sequences.

Common use cases

  • Debug query strings: Decode parameters from tracking links, API requests, or redirects.
  • Prepare safe URLs: Encode search terms, callback URLs, filenames, and form values.
  • Inspect copied links: Understand what a long encoded URL actually contains.

Encoding note

Different contexts encode spaces and reserved characters differently. A value that is safe in a query parameter may not be safe in a path segment, so check the exact place where the value will be used.
