URL Encoder & Decoder

Component mode (encodeURIComponent) escapes every reserved character — including & = ? / # — so it's right for a single query value or path segment. Full URL mode (encodeURI) leaves the URL structure intact, escaping only characters that are never valid in a URL. Use Component for parameters, Full URL when you have a whole address.

No — encoding and decoding run entirely in your browser, nothing is uploaded. As an EU-built, EU-hosted provider, Uptimeify keeps your workflow off US infrastructure and clear of US Cloud Act exposure, which matters for agencies handling client data under GDPR.

Monitoring URLs with query strings, tokens or redirect targets need correct percent-encoding or checks break. Encode parameters here while building a check, then let Uptimeify watch the exact URL — including the full redirect chain and response — and alert you when something changes.
