How to URL-encode text
To encode text for a URL, paste it into URL Encoder and choose the mode that matches where it is going. The tool percent-encodes characters that are unsafe in that context — spaces become %20, ampersands and equals signs are escaped where needed — and returns one copy-ready string you can drop into a link.
The right encoding behavior depends on the destination, which is why the tool keeps the main URL contexts separate. Query strings are encoded key-by-key and value-by-value instead of treating the whole string like one segment, so reserved characters that separate parameters stay intact while the actual values are escaped.
All encoding happens locally in your browser. The text you paste never leaves your device, which keeps internal values, tokens, or unpublished campaign links private.

How query strings differ from full URLs
URL Encoder treats a query string differently from a full URL. For query strings it encodes each key and value separately, preserving the separators between parameters, so the result is a valid, parseable query rather than one over-escaped blob.
This page is the reverse of the URL Decoder tool and shares the same mode structure, so you can move between encode and decode work more safely. Choosing the matching mode on both sides keeps round-trips clean and predictable.
