Resolve a relative URL against a base

Developers and SEO specialists use it to obtain an absolute address from a relative link before testing navigation or a crawl.

Resolve a relative URL against a base. Everything runs in your browser, so the values you enter are never uploaded, shared, or stored.

How to use

Enter the full base address on the first line, including the protocol and reference path.
On the next line, type the relative address to resolve, such as a path starting with dots or a slash.
Run the solve action to obtain the corresponding absolute address.
Read the result and check that the domain, folder and final file match what you expect.
Clear the fields if you want to test another combination.

Example

A developer preparing a link check needs the absolute address of an image referenced relatively from a given page. They enter the base address and the relative path, run the solver and confirm that the resulting address points to the right folder before starting the check.

Input

https://example.com/folder/page
../image.png

Output

https://example.com/image.png

Limits and formats

The tool only resolves an address according to URL composition rules; it does not verify that the resource exists.
It does not follow redirects or test the response time of the final link.
An incorrect base address produces an incorrect absolute address, even if the calculation itself is valid.
Normalisation edge cases can vary between browsers, so check the result in your own context.

Where processing happens

The resolution happens entirely inside your browser. The base address and relative address you enter are not uploaded outside. The calculation stays on your device until you close the page or clear the fields.

Frequently asked questions

What is relative URL resolution used for?

It turns a relative path into an absolute address by combining it with a base address. This is useful when checking a link, preparing a crawl or understanding which resource a reference in a page really points to.

Can the tool confirm that the link works?

No, it only calculates the absolute address from the two values you provide. It does not contact the site and cannot say whether the resource exists, is reachable or redirects somewhere else.

What happens if the relative address contains dot segments?

Segments such as a single dot or double dot are taken into account during composition. The result should show the final folder after moving up or down, but review it if your base address already contains parameters or unusual cases.
