URL Encoder, Decoder & Parser

Percent-encode or decode URLs and query values, and break any URL into protocol, host, path and an editable query-parameter table.

About URL Encoder, Decoder & Parser

This URL encoder and decoder percent-encodes text for safe use in web addresses and decodes %20-style strings back into readable text. Choose Component to encode a single query value, Full URL to keep the address structure intact, or Decode to reverse it.

A URL parser breaks any link into its protocol, host, path and query parameters, which you can edit, add or remove before copying the rebuilt URL. It is useful for developers, marketers building UTM links and anyone debugging a long link. The tool handles UTF-8, is free, needs no sign-up and runs in your browser.

How to use URL Encoder, Decoder & Parser

  1. Type or paste text in the encoder and choose Component, Full URL or Decode.
  2. Copy the encoded or decoded result.
  3. Paste a full link in the URL parser to see its parts.
  4. Edit, add or remove query parameters and copy the rebuilt URL.

Frequently asked questions

encodeURIComponent or encodeURI — which should I use?

Use Component for a single value that goes inside a query string (it encodes & = ? /). Use Full URL for a complete address — it leaves the URL structure characters alone.

Why does a space become %20 or +?

Percent-encoding turns a space into %20. HTML forms use + for spaces in query strings; tick “Treat + as space” when decoding such values.

What does “URI malformed” mean?

The text contains a % that is not followed by two valid hex digits, or an incomplete UTF-8 sequence. Fix or remove the stray % sign.

What is URL encoding?

URL encoding, or percent encoding, replaces characters that are not allowed in a URL with % followed by their hex code, such as a space becoming %20.

How do I decode a URL?

Choose Decode and paste the encoded link; %20, %2F and similar codes are turned back into normal characters.

How do I edit query parameters in a URL?

Paste the link in the URL parser, change the values in the table and copy the rebuilt URL.
