Long tracking URLs, made legible

Split a URL into its query parameters and decode them, so percent-encoded values become readable text.

Marketing and analytics URLs turn into unreadable strings of parameters and percent-codes. Reading them by eye is slow and easy to get wrong.

This splits the query into one parameter per line and decodes each value, so %D0%BF%D1%80%D0%B8%D0%B2%D0%B5%D1%82 comes back as actual words.

What this calculator shows

Every parameter as a name and decoded value
How many parameters the URL carries
The base URL with the query stripped off

What to keep in mind

Accepts a full URL or a bare query string.
Plus signs are decoded as spaces, following form-encoding conventions.

FAQs

What are utm parameters?

Tags analytics tools read to attribute a visit: source, medium, campaign and so on. They affect tracking only, never the page content.

Why do URLs contain % followed by numbers?

That is percent-encoding. Characters outside the safe URL set are stored as their byte values in hexadecimal, which is why Cyrillic becomes a long sequence.

Can a parameter appear more than once?

Yes, and it is common for multi-select filters. Each occurrence is listed separately here; how a server treats duplicates varies.

Is anything after the # included?

No. The fragment is handled by the browser and never sent to the server, so it is excluded from the parameter list.

Worked example

A tracked search link

Input: https://example.com/search?q=%D0%BF%D1%80%D0%B8%D0%B2%D0%B5%D1%82&page=2&utm_source=newsletter

Output: q = привет · page = 2 · utm_source = newsletter

Note: The decoded value shows what was really searched for, which the raw percent-codes completely hide.
