Quick answer

Paste a URL or URL component into Kivrum, choose Encode to convert spaces and reserved symbols into percent-encoded text, or choose Decode to restore readable characters. Copy the result when finished.

What is URL encoding?

URL encoding, also called percent encoding, represents characters that may be unsafe or ambiguous inside a web address. For example, a space commonly becomes %20 while other symbols are replaced by a percent sign followed by hexadecimal digits.

Encoding is especially useful for query-string values, redirect parameters, filenames, and data passed between web applications.

How to encode or decode a URL

Use the tool in four quick steps.

  1. 1

    Paste the text

    Enter the complete URL or only the component you need to transform.

  2. 2

    Choose Encode

    Encode the value before placing it inside a query parameter or another URL component.

  3. 3

    Choose Decode

    Decode percent-encoded text when you need to inspect its readable value.

  4. 4

    Copy the result

    Review the output and copy it into your browser, document, or code.

Common URL encoding examples

Spaces, accented letters, emoji, ampersands, question marks, and equals signs may need encoding depending on where they appear. Always distinguish between a complete URL and a single component such as a search term.

If decoding fails, check whether the text contains an incomplete percent sequence or was encoded more than once.

Private processing in your browser

Kivrum processes the text in your browser, making the tool convenient for everyday development and troubleshooting. Avoid pasting passwords, private tokens, or other secrets into any URL or online workflow.

Frequently asked questions

What is the difference between encoding and decoding?

Encoding converts special characters into a URL-safe percent format. Decoding converts that format back into readable characters.

Should I encode a full URL?

Usually you should encode only the value or component that needs protection. Encoding the full address can change structural separators.

Does URL encoding encrypt data?

No. Percent encoding is reversible formatting, not encryption or security.
