Encode or decode URL components safely in your browser.
About this url encoder decoder
Encode query parameters, decode copied URLs, and make text safe for links without using a server-side tool.
Mavis Tools is built for quick utility work: paste the input, get the result, and move on. The page is static-first for speed, and the interactive work happens in your browser. That makes it useful for drafts, calculations, debugging snippets, and repeat everyday tasks.
This tool is intentionally focused. It does one job clearly instead of asking for an account or hiding the result behind a long workflow. Bookmark it if you need a fast url encoder decoder that works on desktop and mobile.
FAQ
What does URL encoding do?
It converts characters into a format that can safely appear in URLs.
Should I encode a full URL or just a parameter?
Most of the time, encode only the parameter value.
Is the text uploaded?
Yes. The tool runs in your browser, and the input is not uploaded to a server.
