What is the URL Encoder?
The URL Encoder converts any text into a URL-safe percent-encoded string. Spaces become %20, special characters become %XX escapes, and non-ASCII characters are UTF-8 encoded first.
Use it when building query strings by hand, sharing search terms, or preparing data for form submission.
Who is the URL Encoder for?
Web developers building links, marketers preparing UTM parameters, testers crafting API calls, and support staff sharing pre-filled search URLs.
Why use the URL Encoder?
- Uses encodeURIComponent for maximum safety.
- Handles UTF-8 for any language.
- Live preview updates as you type.
- Zero server calls.
- Works offline.
When should I use the URL Encoder?
- Adding a search term to a query string.
- Building a UTM-tagged campaign URL.
- Preparing a pre-filled Google search share link.
- Escaping filenames used in path segments.
- Crafting an OAuth redirect URL manually.
Is the URL Encoder safe and private?
Yes. This tool runs entirely inside your browser - your text is never uploaded, stored on our servers or shared with third parties. You can even disconnect from the internet after the page loads and it will keep working. That makes it safe for confidential notes, drafts, private messages and unpublished work.
How do I get the best results from the URL Encoder?
- Encode each query parameter value separately.
- Do not double-encode - encode once, share once.
- Spaces in URLs should always be encoded as %20 or +.
- For encoding whole URLs, use a tool that respects reserved characters.
Frequently asked questions
What is URL encoding?
URL encoding - also called percent encoding - replaces unsafe characters like spaces with a %-followed hex code so URLs stay valid.
What is the difference between encodeURI and encodeURIComponent?
This tool uses encodeURIComponent, which encodes everything unsafe including &, ? and =. Use it for individual query parameter values.
Does it work with non-English characters?
Yes. Non-ASCII characters are UTF-8 encoded then percent-escaped following the URL standard.
Is my input uploaded?
No - encoding happens in your browser.
