Frequently asked questions
How do I use URL Encoder & Decoder?
Enter or choose your input in the tool above. The result updates immediately or appears when you select the action, ready to copy or download.
What's the difference between encoding a component and a full URL?
Component encoding escapes characters like & and = so a value stays intact inside a query string, while full-URL encoding preserves the structural characters of the address.
Is URL Encoder & Decoder free, and is my data private?
Yes. URL Encoder & Decoder is free with no account or watermark, and it runs entirely in your browser so your input is never uploaded, stored, or shared.
Does it work on phones and tablets?
Yes. It works in current browsers on Android, iPhone, iPad, Windows, macOS, and Linux.
