BIB to RIS
Converting a .bib font to .ris repackages the same glyphs and metrics for a different delivery target. Free, private, and validated — the file never leaves your browser.

Converting a .bib font to .ris repackages the same glyphs and metrics for a different delivery target. A .bib file is a BibTeX database: a list of records, each opening with an @type and a citation key and then a set of field = {value} pairs. It separates what a reference *is* from how a journal wants it printed, which is the whole idea.
A .ris file is a citation list in a strict tagged format: every line begins with a two-character tag, then exactly two spaces, a hyphen and a space, then the value. A record starts with TY and ends with ER, and that rigidity is why it interoperates so reliably. For this route the practical draw is rigid enough that implementations genuinely agree and supported by essentially every academic database and reference manager — balanced against tag vocabulary varies by vendor, so some fields are lost in transit, which is worth knowing before you commit a large batch.
Why convert BIB to RIS?
The practical trigger for this conversion is usually a mismatch: with .bib, no formal specification, so parsers disagree at the edges. Switching to .ris buys you rigid enough that implementations genuinely agree, which is why it is the better fit for importing search results from PubMed, Scopus or Web of Science into a reference manager. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
BIB vs RIS at a glance
| Aspect | BibTeX bibliography (.bib) | Research Information Systems citation (.ris) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | each record is @type{key, field = {value}, ...}, where the type (article, book, inproceedings, misc) determines which fields are required | the tag column is fixed width: two characters, two spaces, a hyphen, a space. A single space instead of two is the most common export bug, and strict readers reject it |
| Strongest at | managing references for LaTeX papers and theses | importing search results from PubMed, Scopus or Web of Science into a reference manager |
| Weak spot | no formal specification, so parsers disagree at the edges | tag vocabulary varies by vendor, so some fields are lost in transit |
| Metadata | all standard bibliographic fields are carried into the JSON output; CSV flattens them to one row per record | core bibliographic tags are preserved; vendor-specific tags outside the shared model are dropped and the page says so |
Pick RIS as the output
Select .ris in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if RIS is selectable, the route is real and validated.
Convert on your device
Press Convert. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid RIS file. Outputs keep the original filename with the .ris extension.
BIB to RIS questions, answered
Will converting BIB to RIS lose quality?
There is no visual quality to lose — bib is text-oriented and ris is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert BIB files here?
Yes — the .bib file is processed inside your browser tab and never uploaded. The font tables are parsed and rewritten locally with fonteditor-core; glyph outlines, hinting, and kerning survive the trip. Close the tab and the file is gone from memory.
Where will the RIS file work?
Zotero, Mendeley, EndNote, RefWorks, Papers and every major academic database read RIS. Novus Convert converts it locally to BibTeX, JSON and CSV through the same bounded citation model, so a RIS to BibTeX round trip preserves the core bibliographic fields.
Will the RIS file be bigger or smaller than my BIB?
It depends on the content: the tag column is fixed width: two characters, two spaces, a hyphen, a space. A single space instead of two is the most common export bug, and strict readers reject it. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my BIB file?
In .bib, all standard bibliographic fields are carried into the JSON output; CSV flattens them to one row per record. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert RIS back to BIB?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .bib → .ris → .bib is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
