BibTeX to RIS Converter
Turn a .bib file into a .ris file for EndNote, Mendeley, RefWorks, Zotero, Rayyan or Covidence.
- Free, no sign-up, no limits
- Converts in your browser
- Nothing uploaded or kept
Word (.docx), .bib, .ris and .txt files work. Each reference is looked up in free public databases; nothing is stored by LetRelay.
How to use it
Paste or add your .bib
Paste BibTeX entries or add the .bib file from Overleaf, JabRef or Google Scholar.
Convert
Each entry becomes an RIS record straight away, in your browser.
Download the .ris
Import it into EndNote, Mendeley, RefWorks, Zotero, Rayyan or Covidence.
The conversion happens in your browser in a moment and the file is not uploaded; LaTeX accents and braces become plain text and each entry type maps to its RIS type (@article to JOUR, @inproceedings to CPAPER, @book to BOOK).
Converted in your browser
The BibTeX you paste is read and rewritten on this page; nothing is sent anywhere unless you tick “Also check every entry”, which looks each one up in Crossref, OpenAlex and PubMed and fixes wrong details on the way. Every entry type maps to its counterpart, authors keep their given names, and LaTeX accents ({\"o}, \&, --) become plain text.
