About URL Encode Decode

The tool encodes and decodes percent-encoding for URL components, full URIs, and application/x-www-form-urlencoded values. It shows stable errors for malformed % escapes, invalid UTF-8 bytes, invalid Unicode, and oversized input.

How to encode and decode URLs online

Paste the input, choose encode or decode, select the correct context, and copy or download the output. Shared links preserve only settings by default; include input in the link only when it can be public.
