Frequently Asked Questions
Everything that JavaScript's native encodeURIComponent() encodes — spaces, &, ?, #, /, and other characters reserved in URLs — converted to their %XX percent-encoded form.
It uses encodeURIComponent, meant for individual URL components (a query parameter value, a path segment) — it will also encode characters like / and : that you might want preserved in a full URL. For encoding an entire URL while preserving its structure, encode only the specific parts that need it.
Yes — switch to the Decode tab to run decodeURIComponent instead.
No — encoding happens entirely in your browser.
