FAQ
URL Encoder / Decoder questions.
What is URL encoding?
Also called percent-encoding, it replaces characters that are unsafe in URLs, like spaces and ampersands, with a percent sign and hex code. A space becomes %20. It keeps URLs valid and unambiguous.
When should I encode a URL?
Whenever a URL contains spaces, non-English letters or reserved characters like ?, & and = inside a value. Query parameters with user input almost always need encoding to avoid breaking the link.
What is the difference between Whole URL and Single value?
Whole URL keeps the structure (://, ?, &, =) and existing %XX escapes, so nothing is encoded twice. Single value encodes every reserved character, which is what you want for one query value or path segment.
Is my input uploaded?
No. Encoding and decoding run entirely in your browser. Nothing you paste is sent anywhere.
