URL Encoder / Decoder
Percent-encode and decode URLs and text. Results update as you type.
Free online URL encoder and decoder
The Ajenza URL Encoder / Decoder converts text to and from percent-encoding (URL encoding) in your browser. Use Component mode to encode a single query value — spaces, slashes, ampersands and other special characters all become safe — or Full URL mode to encode a whole address while keeping its structure intact. Switch to Decode to turn %-encoded text back into readable characters. Results update live, you can swap input and output to reverse a conversion, and everything is processed locally so nothing is uploaded.
Is it free?
Yes — completely free, with no sign-up, download or watermark.
Component vs Full URL?
Component encodes everything (for one query value); Full URL keeps :/?&= intact (for a whole address).
Do I need to install anything?
No. Everything runs in your browser.
