BibTeX to APA Converter

Free. No signup. Runs in your browser.

Paste a bib File and Convert to APA 7 bibliography back. The official CSL style file is used (the same one Zotero ships), accent macros (\"a) render as proper diacritics, brace-protected acronyms survive the case-folding step, and the entry type can be overridden per row when CrossRef tagged something wrong. Ready to drop into your manuscript.

How to convert BibTeX to APA online

Visit the BibTeX to APA tool page You’re already here. Bookmark thelatexlab.com/bibtex-to-apa/ for next time.
Step 1
Upload or paste your .bib Drop a .bib file using the upload button, or paste the BibTeX text directly. Single entries and large libraries both work. Accent macros (\"a, \'e) and brace-protected acronyms ({DNA}) are read correctly.
Step 2
Confirm APA is the right style APA 7 (the current edition) is the default. If your journal or institution still requires APA 6, you’ll need to adjust by hand – the differences are well-documented (et al. threshold dropped from 6 to 3 authors, DOI prefix changed from doi: to https://doi.org/, removal of publisher location for books).
Step 3
Convert, then copy or download Each entry renders as a formatted APA reference with a per-row entry-type override and Copy button. Use Copy all at the bottom to grab the whole bibliography in one go.
Step 4
Parsing and rendering both happen in your browser – the .bib content never leaves the tab. Entries that fail to render show up inline with the reason so you can fix or drop them without losing the rest of the batch.

Where most BibTeX to APA converters break

They render an older APA edition APA 7 has been the current edition since 2019, but plenty of free converters still ship APA 6 – which uses a different et al. threshold (6 authors, not 3), a different DOI prefix (doi: not https://doi.org/), and different publisher-location rules. The tool uses the official APA style file from the CSL Style Repository – the same source Zotero, Mendeley, and Pandoc use – which tracks the current edition.

Accent macros end up in the output A BibTeX entry with author = {Kr{\"a}mer, M.} should render as “Krämer, M.” in APA. Converters that don’t parse BibTeX accent macros either pass them through (Kr"amer) or crash. The tool uses Citation.js’ BibTeX parser, which handles the full accent-macro set (umlaut, acute, grave, tilde, caron, ring, cedilla, ogonek, slash), brace-nested protection, and BibLaTeX field aliases.

Sentence-case rules get applied wrong APA uses sentence case for article titles (“Deep learning for natural language processing”) but title case for book and journal names (“Nature Machine Intelligence”). The CSL APA style handles the case conversion automatically – but only if the BibTeX title was brace-protected at the right granularity. {DNA} stays capitalised; {Deep Learning} wraps the whole thing and bypasses case conversion entirely. If you’re seeing unwanted capitalisation, check whether the source title is over-braced (a frequent issue in Word-exported references).

Entry type tagged wrong upstream An entry tagged @article renders very differently from one tagged @inproceedings under APA – the latter gets a conference-name field, location, no journal. CrossRef tags conference papers as journal-article often enough that this happens routinely. The tool exposes a per-row entry-type override that switches the type and re-renders the citation without leaving the page.

Output is plain text by default. For HTML with italics and proper hanging indent, switch the To pill to “HTML” and re-render. CJK / Arabic / Cyrillic names render under Unicode-aware bibstyles – they pass through the renderer correctly but your final document needs a font that has glyphs for the script.

Frequently asked questions

APA 7. The current edition has been APA 7 since 2019. The main differences from APA 6: drop to “first author et al.” at 3 authors instead of 6, DOIs render as https://doi.org/... rather than doi:..., no publisher location for books, and a few formatting tweaks. If your institution still mandates APA 6, you’ll need to adjust by hand – the differences are bounded and predictable.

APA uses sentence case for article titles. If your source BibTeX has title = {{Deep Learning for NLP}} with double braces around the whole title, the CSL renderer treats it as already-protected and skips case conversion – so you get “Deep Learning for NLP” instead of “Deep learning for NLP”. The fix is to remove the outer braces and protect only the acronyms: title = {Deep learning for {NLP}}. The reverse problem (acronyms getting lowercased) means the acronyms weren’t braced at all.

Three common culprits: (1) the file is actually RIS, EndNote, or NBIB (the converters for those are on separate pages – /ris-to-bibtex/, /endnote-to-bibtex/, /nbib-to-bibtex/); (2) a missing closing brace – one bad entry blocks the parser at that point (the missing brace fix walks through the diagnosis); (3) @string macros without definitions, common in journal-shorthand .bib files. Each failing entry shows up inline with the reason.

The default output is the bibliography list, plain text. Switch to HTML for italic journal names and the hanging indent. In-text citations (“(Smith, 2020)” or “(Smith et al., 2020)”) aren’t part of the standard bibliography render – they’re a separate CSL output mode that needs the surrounding sentence for context. For now, build them by hand from the bibliography output.

Free, no signup. Parsing and rendering both run entirely in your browser – the .bib file or pasted text never touches our server, no network call is made. The output exists in your browser session and disappears when you close the tab.
