DOI to Citation
Paste a DOI and get a formatted citation in APA or AMA style. Metadata comes straight from the official CrossRef registry.
How to convert a DOI to a citation
A DOI (Digital Object Identifier) is the permanent identifier stamped on most published papers, like 10.1038/nature12373. Paste it with or without the https://doi.org/ prefix — both work.
The tool queries the CrossRef registry, the same database DOI resolvers use, so the citation reflects the publisher's own registered metadata. If a paper has no DOI (older or non-registered venues), use the PMID to Citation tool instead.
