This tool is fully client-side, so nothing gets uploaded. Just paste a URL or query string and click “Encode.” It supports complete RFC 3986 URL encoding standards and works for GET parameters, path values, form data, and more.
Use it to sanitize URLs for email links, browser use, web development, and query APIs correctly.
How to Use URL Encoder Online

URL Encoder Online Use Cases
1. Encode URLs for APIs
Ensure your query strings are safely passed in API calls. Use the tool to encode parameters like ?name=John Doe

Avoid URL truncation or misinterpretation in emails by encoding ampersands, equal signs, and slashes.

When passing user inputs or third-party URLs in redirect links, encoding ensures the parameters don’t break your logic.

Make sure GET-based form data containing special characters like &
, =
or +
don’t cause errors on submission.

FAQs About URL Encoder Online
What does URL encoding mean?
URL encoding replaces unsafe characters in a URL with %
followed by two hexadecimal digits. It ensures the URL is transmitted correctly over the internet and avoids interpretation issues in browsers or servers.
When should I use URL encoding?
Use it whenever your URL contains special characters like spaces, ampersands, or equal signs—especially in query strings, paths, or form submissions.
What characters are encoded?
Characters like
(space), &
, ?
, #
, =
, +
, and many non-alphanumeric characters are encoded to avoid misinterpretation in web systems.
Will this work on international characters?
Yes, it handles full Unicode input and converts non-ASCII characters like ñ
, ü
, or Chinese/Arabic scripts into proper percent-encoded sequences.
Can I decode URLs with this tool?
No. For decoding, use our URL Decode tool which converts percent-encoded text back to its readable form.
Does this tool work offline?
It’s browser-based and doesn’t require internet after the page loads, so you can continue encoding URLs even without a connection.
Is my data stored or tracked?
No. All encoding happens in your browser using JavaScript. Nothing you enter is uploaded, saved, or shared.
Can I encode only parts of a URL?
Yes. You can encode a full URL or just a query string, path, or individual text input.
Is this tool safe to use in production workflows?
Yes. It follows the RFC 3986 standard and is safe for integration workflows, automation, or quick manual use.
Why do URLs need encoding?
URLs must comply with HTTP standards. Characters like space or &
can break the format or cause unexpected behavior unless encoded properly.
Can I batch encode multiple URLs?
Currently, it supports single-input encoding. For batch support, consider using it programmatically or via browser extensions.
