RIS to BibTeX Converter
Processing entirely on your device — large files may take a moment.
Research Information Systems and BibTeX Bibliography exist for different jobs: RIS is the tagged bibliographic format every reference manager imports and exports — TY lines, AU authors, ER terminators. Zotero, Mendeley and EndNote all speak it. Convert BibTeX libraries to RIS for Zotero/Mendeley, or to JSON for custom reference tooling.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the RIS format
RIS is the tagged bibliography format that became the lingua franca of reference management: two-letter tags (TY for type, AU for author, ER for end) describe one citation per block. Zotero, Mendeley and EndNote all import and export it.
Converting RIS to JSON turns citations into data your scripts can query — de-duplicate libraries, merge collections or feed custom review tooling without a reference manager in the loop.
+Strengths
- ✓Universal in reference managers
- ✓Simple line-tagged format
!Limitations
- −Only one record type per block
- −Field mapping varies by vendor
About the BibTeX format
BibTeX is how the LaTeX world stores citations: @article{key, author={...}, title={...}} entries that cite commands resolve into bibliographies. Decades of academic writing live in .bib files, and the arXiv-to-paper workflow depends on them.
Converting BibTeX to JSON makes citation data queryable for dashboards and review tooling; converting to RIS hands it to Zotero or Mendeley users without LaTeX in the loop.
+Strengths
- ✓Standard of the LaTeX ecosystem
- ✓Decades of accumulated references
!Limitations
- −String concatenation syntax is fiddly
- −No official specification document
Why convert RIS to BibTeX?
Converting makes sense where the strengths of BibTeX meet what RIS cannot give you. Standard of the LaTeX ecosystem Meanwhile Only one record type per block One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this RIS to BibTeX converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for RIS to BibTeX?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Can I edit the BibTeX result afterwards?
That depends on the target: BibTeX is designed for what it does, and this converter reproduces its content faithfully rather than inventing editable structure. For heavy re-editing, work from a format built for editing and export the final version here.
Will the layout of my RIS file be preserved exactly?
This converter renders your RIS content into BibTeX with pages, proportions and images kept as close to the original as the target format allows. Use the preview before downloading to confirm it looks the way you expect.
