Sample output — your files never leave your device.
It replaces characters that are unsafe or reserved in URLs with % followed by their hex byte value — a space becomes %20, & becomes %26. It lets arbitrary text ride inside a URL without breaking its structure.
Paste the encoded URL or parameter string into the decoder — it converts every %XX sequence back to the original character, giving you readable text.
Whenever a value contains characters with meaning in URLs — &, =, ?, spaces, # — or non-ASCII text. Encoding the value prevents it from corrupting the query string's structure.
