Frequently Asked Questions

Is the URL encoder free?

Yes, completely free. No signup, no limits on usage, and no ads.

Is my data kept private?

Yes. All encoding and decoding happens in your browser. Your URLs and data are never transmitted to any server.

What characters need URL encoding?

Spaces, &, ?, =, #, %, +, and non-ASCII characters (including accented letters, CJK characters, and emojis) all need encoding when used in URL query parameters.

Can I use this for building API URLs?

Yes. URL encoding is essential when constructing API requests with query parameters that contain special characters or user input.

How does this compare to urlencoder.io?

Both handle URL encoding correctly. MyToolbox processes everything client-side and offers a cleaner, ad-free interface.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URI but leaves certain characters like : / ? & intact. encodeURIComponent encodes everything except letters, numbers, and - _ . ~ — making it correct for individual query parameter values.

Does this work offline?

Yes. Once the page is loaded, all encoding and decoding works without an internet connection.

Is there an input size limit?

No practical limit for the tool itself. Keep in mind that most browsers and servers have their own URL length limits (typically 2,000 to 8,000 characters for full URLs).
