ONE SMALL TASK, DONE.

URL Component Encoder

Encode or decode a URL parameter value using UTF-8 percent escapes.

Processed on your device

Paste text, open a file or try the sample to begin.

How to use

  1. Paste a parameter value or an encoded string.
  2. Choose encode or decode.
  3. Copy the result.

Good to know

Use this for a parameter value or path segment, not a complete URL.

Invalid percent escapes produce an error. The optional + conversion is for form-encoded values.

Text files up to 5 MB are supported. Downloads are encoded as UTF-8.

Your input is processed by this tool on your device. It is not uploaded to our server. Advertising uses external services. Social and coffee links open external websites.

Questions

Why not encode the whole URL?

Encoding a full URL also escapes :// and / and breaks it. Encode only the value that goes after = in a query string.

What does the plus option do?

Form submissions write spaces as +. Turn it on when decoding such values.
