URL Encoder & Decoder
Percent-encode or decode URL components and full URLs locally with strict Unicode validation.
Best for a query value, path segment, redirect target, or other value placed inside a URL.

This tool uses percent-encoding, not encryption. It does not treat + as a space; HTML form encoding follows different rules. Processing stays in your browser.
Data handling
Storage and export controls
- Retention
- The tool's working state is kept only while this page is open. Inputs and results are not saved to persistent storage by Got A Tool.
- Export
- The tool may prepare a result after you run it. It downloads or copies it only when you choose that action.

How it works
Encode URL text in three steps
02
Choose the scope
Encode an individual URL component or preserve the structure of a complete URL.
03
Copy or reverse
Copy the validated result or move it into the input and reverse the operation.
Standards-based behavior
Choose what belongs to the URL structure.
Component mode encodes delimiters so a value can safely occupy one URL part. Full URL mode preserves structural delimiters while encoding spaces, Unicode, and unsafe characters.
Unicode support
Encodes international text and emoji as their UTF-8 percent-escaped bytes.
Strict decoding
Rejects incomplete escapes, invalid hex pairs, and byte sequences that are not valid UTF-8.
Two scopes
Mirrors encodeURIComponent/decodeURIComponent and encodeURI/decodeURI behavior.
Local processing
No URL or text is requested, visited, uploaded, or stored by Got A Tool.
FAQ
Common questions
Should I encode a component or a full URL?
Use component mode for a query value, path segment, redirect target, or other value inserted inside a URL. Use full URL mode when the input already contains URL structure such as a scheme, host, path, query, and fragment.
Why does full URL mode preserve some percent escapes when decoding?
Reserved delimiters can change a URL's structure. Full URL decoding follows decodeURI behavior and preserves encoded reserved characters; component mode decodes them when the value is a single component.
Does a plus sign decode to a space?
No. This tool implements URI percent-encoding, where a plus sign remains a plus. The plus-as-space convention belongs to application/x-www-form-urlencoded form data.
Is URL encoding encryption?
No. Percent-encoding is reversible formatting for URLs and provides no secrecy or security by itself.
Does the tool visit or validate my URL?
No. It transforms the text locally in your browser and makes no request to the entered address.
