Why use Wivrix?
Many online tools ask you to sign up, add a watermark, or upload your files to a server you cannot see. Wivrix is different:
- Private by design — Everything runs in your browser. Your files and input stay on your device — nothing is uploaded to Wivrix.
- Free — no account, no paywall, no file-size tricks
- Fast — open the page and start working
Step-by-step guide
- URL Component — encodes every special character including ? and & . Use this for a single query parameter value.
- Full URL — preserves structural characters like :// and ? . Use this to encode an entire URL.
- Builder — enter key-value pairs and generate a properly encoded query string.
- Parser — paste a query string or URL and see all parameters as a table and JSON object.
