How to convert bib to ris file

Reference managers, manuscript systems, and library databases may require RIS when they cannot import BibTeX directly. Converting a BibTeX bibliography lets you move citation records into software such as EndNote, Zotero, RefWorks, or Mendeley without re-entering them.
What the BIB format is
For text files, .bib normally identifies a BibTeX bibliography: a plain-text file containing entries such as @article, @book, and @inproceedings. Each entry has a citation key and fields such as author, title, year, journal, volume, number, pages, doi, and url.
LaTeX projects using BibTeX or Biber create and read these files. JabRef, BibDesk, Zotero, Overleaf, and other reference managers can also create or export them. A BIB file commonly comes from a scholarly publisher, a LaTeX project, or a reference-management export.
What the RIS format is
RIS is a plain-text exchange format for bibliographic records. A record uses two-letter tags followed by a hyphen and value, for example TY - JOUR for the record type, AU - for an author, TI - for the title, JO - or JF - for a journal, PY - for the publication year, and DO - for a DOI. ER - ends each record.
RIS is accepted by EndNote, Zotero, RefWorks, Citavi, Mendeley, many library catalogs, and manuscript-submission systems. Its separate author lines and standardized tags make it convenient for exchanging references between applications outside the LaTeX ecosystem.
Convert with JabRef
- Install a current version of JabRef and open the
.bibfile. - Check for parsing errors, missing required fields, malformed braces, and incorrectly escaped characters.
- Select the entries to export, or select all entries.
- Choose File → Export, select the RIS output format, and save the file as
references.ris. - Import the RIS file into the destination program and inspect record types, author names, page ranges, DOI values, dates, and capitalization.
JabRef is suitable when the records need editing before export. It also keeps the conversion local, so the bibliography does not need to be uploaded.
Convert with Bibutils
Bibutils provides a repeatable command-line conversion through its intermediate XML format. After installing Bibutils, run:
bib2xml references.bib | xml2ris > references.ris
To retain the intermediate file for troubleshooting, run:
bib2xml references.bib > references.xmlxml2ris references.xml > references.ris
Install Bibutils from the operating system's package manager or use its compiled binaries if the commands are not on the executable path. This option is useful for batch jobs and reproducible scripts. Bibutils may require adjustments for unusual entry types or fields, so validate the resulting records.
Use an online converter
For a public, non-sensitive bibliography, a browser-based BibTeX/RIS converter such as the Citation.js web demo can handle a one-off conversion. Confirm that the service supports BibTeX input and RIS output, check its privacy policy, and download the result rather than relying on a server-side copy. Do not upload unpublished references, private notes, file paths, or other sensitive metadata; use JabRef or Bibutils for those files.
Quality and compatibility checks
BibTeX and RIS have different type and field vocabularies. @misc, @online, custom entry types, and publisher-specific fields may become generic RIS records or be omitted. Abstracts, keywords, local file links, BibTeX-only options, and custom fields require particular checking after import.
Author syntax also changes: BibTeX can store names as Last, First, First Last, or institutional names protected by braces, while RIS normally uses one AU line per author. Verify compound surnames, particles, suffixes, corporate authors, and author order.
Keep the original BIB file and treat the RIS file as an export, not a replacement. Modern tools generally handle UTF-8, but older RIS implementations may damage accented characters, non-Latin scripts, en dashes in page ranges, or brace-protected capitalization. Open the output in the target application and correct any damaged encoding or title capitalization before using it in a manuscript.

Frequently asked questions
Is the BIB to RIS converter free?
Yes, converting BIB 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 BIB file be?
You can upload BIB 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 BIB to RIS?
No. The BIB 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 BIB file for this BIB 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 converting BibTeX to RIS lose my citation keys?
Usually, the BibTeX citation key is not preserved as a standard RIS field. It may be placed in a note or custom field, depending on how the converter maps the entry.
Are all BibTeX fields preserved in an RIS file?
No, only fields with a clear RIS equivalent are reliably preserved. BibTeX-specific, custom, and less common fields may be omitted or moved into notes, and some entry types may be mapped approximately.
Why do author names or accented characters look wrong after BibTeX to RIS conversion?
This usually happens when LaTeX character commands or BibTeX name formatting are not interpreted correctly by the RIS converter. Check the text encoding and review names with accents, suffixes, or multiple authors in the converted records.
Can I convert an RIS file back to BibTeX without changes?
Not always, because RIS and BibTeX organize entry types and fields differently. The main citation details may survive, but custom fields, citation keys, formatting commands, and unsupported metadata can be changed or lost.
