Quick Start

Paste text into the editor and click toolbar buttons or one-click actions. Output appears in the result area.

Use encodeURIComponent for URL parameter values; encodeURI is for whole URLs.
Form encoding uses + for spaces, not %20; replace + with spaces before decoding if needed.
Base64 has a URL-safe variant (- and _) that differs from standard + and /.
Trim whitespace and blank lines before deduplication for better results.

Select text and click a toolbar button to apply; output can be copied in one click.
In compact view, enable Auto Apply to update the result while editing.
