URL Encoder and Decoder
Encode or decode text in the percent format used in URLs.
URL Encoder and Decoder is a free tool that runs entirely in your browser, with no data ever sent to a server. Encode or decode text in the percent format used in URLs.
What it's for
Build a link containing special characters or accents, or decode an unreadable URL received by email to understand what it actually contains.
What this tool does not do
This tool only applies the transformation described, with no spellchecking and no interpretation of the text's meaning. A text of several tens of thousands of lines processes instantly; beyond that, the only limit is your device's memory.
Frequently asked questions
Why encode a URL?
Some characters (space, ampersand, question mark...) have a special meaning in a URL. Percent-encoding them keeps them from being misinterpreted.
Is my data sent to a server?
No: the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.
Do I need to create an account or install anything?
No: the tool works directly in this page, with no sign-up and nothing to install.
