Paste a DOI, get a publisher-accurate BibTeX entry — via CrossRef, free, no signup.
Paste a DOI and get a perfectly formatted BibTeX entry from CrossRef. Works for journals, conference papers, books, and datasets.
A DOI (Digital Object Identifier) is the permanent ID attached to most journal articles, conference papers, datasets, and book chapters. Paste it above and the converter queries CrossRef — the registry where publishers deposit their official metadata — and returns a formatted BibTeX entry with the authors, title, venue, year, volume, pages, and the DOI field itself. Copy it straight into your .bib file.
Because the entry is built from the publisher’s registered record, you avoid the two classic citation failure modes: hand-typing errors, and AI-hallucinated references that look plausible but cite papers that don’t exist. Do still give the result a quick glance — capitalization you must preserve (like acronyms) belongs in braces, e.g. {{DNA}}, and some older records carry sparse metadata.
From CrossRef, the DOI registry where publishers deposit the official metadata for their articles. The entry reflects what the publisher registered — not a guess, and not AI-generated text.
A bare DOI like 10.1038/s41586-021-03819-2, or a full link — https://doi.org/… and dx.doi.org links are recognized and the DOI is extracted automatically.
Language models routinely invent plausible-looking DOIs, page numbers, and even entire papers. This tool performs a real registry lookup, so the entry matches the actual publication record.
Preprints are better served by the arXiv converter, and books by the ISBN converter — both free on latexci. If a preprint has been published, prefer citing the journal version via its DOI.
