DOI Finder by URL
Have a paper’s web link but need its DOI? Paste the URL and get the DOI, along with the title, authors and journal. The DOI is pulled straight from the link when possible, or matched from the open CrossRef database.
- Copy the web address of the paper (from your browser’s address bar).
- Paste it below and click Find DOI.
- Copy the DOI, and check the title shown matches your paper.
How to find a DOI from a URL
Sometimes you have the web link to a paper but need its DOI — the permanent identifier journals ask for in citations and submissions. This DOI finder by URL gets the DOI from a paper’s link in two ways.
Two ways it finds the DOI
- Straight from the link. Many links already contain the DOI — for example a doi.org link, or publisher URLs like Nature, PLOS and MDPI that include the DOI. The tool extracts it instantly.
- By best match. Some links (for example certain ScienceDirect or database pages) hide the DOI inside the page. For these, the tool reads the article details from the link and searches the open CrossRef database for the closest matching paper, then shows you the DOI and title so you can confirm it.
Good to know
Because web pages from other sites can’t be read directly from your browser, links that completely hide the DOI rely on the best-match search — so always check that the returned title is the paper you meant. Once you have the DOI, you can use our DOI Lookup for full details or the Citation Generator to cite it. This tool is free and unlimited.
