Free online file tools — no uploads, your files never leave your browser
Every generator here follows the published rules of one citation style and assembles the entry from the fields you type — author order, the punctuation between elements, and the matching in-text citation. The work happens in your browser, so the bibliography you are building never leaves your device.
Two things these tools deliberately do not do. They do not abbreviate journal titles (IEEE uses ISO 4 abbreviations, AMA uses the NLM catalogue, ACS uses CASSI — all three expect you to supply the abbreviated form), and the Bluebook page does not abbreviate case names, because Tables T.6 and T.10 depend on context in ways that cannot be guessed safely. Type the form your own style guide asks for and the tools will place it correctly.
| Style | Used for |
|---|---|
| IEEE | Engineering, computer science — bracketed numbers [1] |
| AMA | Medicine — superscript numbers, NLM journal abbreviations |
| ACS | Chemistry — superscript numbers, CASSI abbreviations |
| APA | Psychology, education, social sciences — (Author, Year) |
| MLA | Humanities — (Author Page), Works Cited |
| Harvard | UK, Australia and many business schools — (Author Year) |
| Turabian | Student version of Chicago: footnotes or author-date |
| Bluebook | US legal citation — cases, law reviews, treatises |
Harvard is the odd one out: there is no single official manual, so conventions vary by institution. Use the Harvard generator to get the structure right and then check it against the guide your own department publishes.
