How to convert bibtex to ris file

A journal submission portal, library database, or reference manager may require RIS when your references are stored in a BibTeX .bib file. Converting the file makes the records importable without retyping each citation.
What the BibTeX format is
BibTeX is a plain-text bibliographic format used with TeX and LaTeX. A .bib file contains entries such as @article, @book, and @inproceedings, with fields including author, title, year, journal, volume, pages, and doi.
BibTeX and Biber read these databases when compiling LaTeX documents. Reference managers such as Zotero, JabRef, BibDesk, Mendeley, and EndNote can also import or export BibTeX. Citation downloads from Google Scholar, Crossref, publishers, and academic library catalogs commonly use this format.
What the RIS format is
RIS is a tagged plain-text exchange format used by reference managers, library systems, repositories, and manuscript-submission services. Each record contains two-letter tags and values, for example TY - JOUR for a journal article, AU - Smith, Jane for an author, TI - Article title for a title, and ER - to mark the end of the record.
RIS is useful when the receiving system specifically requests an .ris file. It is supported by applications including EndNote, Zotero, RefWorks, Citavi, and many institutional library systems. Its repeated author and keyword tags generally transfer bibliographic records more predictably than copying formatted citations.
How to convert a BibTeX file
Zotero is the most straightforward general-purpose option:
- Install the Zotero desktop application from
zotero.org. - Choose File → Import and select the
.bibfile. - Import the records into a new collection or the selected library.
- Check the imported authors, titles, dates, and duplicate records.
- Select the records, open the context menu, choose Export Items..., select RIS, and save the output with a
.risextension.
Zotero handles common BibTeX entry types, Unicode text, and selective export. It is preferable for mixed or moderately large libraries because the conversion remains local.
JabRef suits bibliographies already maintained for LaTeX:
- Open the
.bibfile in JabRef. - Select the entries to export.
- Use File → Export or the release-specific export command for selected entries.
- Choose RIS and save the result as
references.ris.
JabRef menu names and export filters vary by release. Update JabRef if RIS does not appear among the available export formats.
For a small, non-confidential file, a web converter such as the GroupDocs online BIB-to-RIS converter can avoid installing software: upload the .bib file, select RIS, download the result, and inspect it before importing. Do not upload files containing private notes, unpublished research, personal data, or restricted references; use Zotero or JabRef for sensitive or large collections.
Quality and compatibility checks
Conversion is not necessarily lossless. BibTeX permits LaTeX commands, brace-based capitalization, citation keys, custom fields, and entry types that RIS cannot represent consistently. Depending on the converter, fields such as abstract, keywords, file, urldate, and custom metadata may be omitted or mapped to nonstandard RIS tags.
After conversion, check author order, initials, corporate authors, title capitalization, page ranges, publication dates, journal names, DOI values, and non-ASCII characters. A BibTeX name such as {World Health Organization} may require correction so it remains one institutional author. Entries such as @misc, @online, theses, and conference papers may also receive an unsuitable RIS record type and need manual editing.
Open the output in a plain-text editor and confirm that each record has a valid TY tag and ends with ER -. Import it into the target application, compare its record count with the source, and verify that the receiving application preserved the intended fields.

Frequently asked questions
Is the BIBTEX to RIS converter free?
Yes, converting BIBTEX to RIS on 101convert.com is completely free. No registration, email address or installation is required. If you need a higher file size limit or want to convert more files at once, see our plans.
How large can my BIBTEX file be?
You can upload BIBTEX files up to 3 MB and convert up to 3 files at once in a single batch. With a paid plan the limit is up to 5 MB per file and 100 files at once, see our plans.
What happens to my uploaded files?
Files are processed automatically and deleted from our servers within a few minutes after conversion. We never view or share your files.
Do I need to install any software to convert BIBTEX to RIS?
No. The BIBTEX to RIS conversion runs entirely online in your browser and works on Windows, Mac, Linux, Android and iPhone.
Did the conversion fail?
In most cases, the cause is an incorrect file format. Please upload a valid BIBTEX file for this BIBTEX to RIS conversion. Occasionally, the issue may be on our side. We analyze recurring conversion failures and disable or fix the converter if we detect a defect.
Will my BibTeX fields and citation keys be preserved in RIS?
Standard bibliographic fields usually transfer, but BibTeX citation keys, custom fields, and fields without a direct RIS equivalent may be omitted or placed in a less specific RIS field. Check entries that rely on unusual metadata after conversion.
Will LaTeX formatting and accented characters survive BibTeX to RIS conversion?
Common accented characters and basic formatting are often converted, but LaTeX commands, braces, and complex markup may be simplified or remain as text. This can affect titles, author names, and other fields that use LaTeX notation.
Why are my authors or corporate author names wrong after converting BibTeX to RIS?
Author parsing can fail when BibTeX names use unusual separators, missing first or last names, or corporate names that are not enclosed as a single name. The result may split an organization into personal-name parts or change the author order.
Can I convert RIS back to BibTeX without losing information?
A reverse conversion is possible, but it may not restore omitted custom fields, BibTeX-specific citation keys, cross-references, or the original LaTeX formatting. The converted RIS remains editable as citation metadata, but it is not necessarily an exact copy of the original BibTeX source.
