Format citations in APA, MLA, and Chicago styles.
A free, privacy-first online tool to format citations in APA, MLA, Chicago, and other academic styles directly in your browser.
5 citation styles: APA 7th, MLA 9th, Chicago 17th, IEEE, Harvard. 4 source types: Book, Journal Article, Website, Book Chapter. Style-specific formatting per source type (different ordering, punctuation, and prefixes). DOI and URL field with style-appropriate placement.
Select your citation style from 5 options: APA 7th, MLA 9th, Chicago 17th (Notes-Bibliography), IEEE (numbered references), or Harvard (author-date). Each style handler implements the specific formatting rules, punctuation, and ordering conventions for that style.
Select the source type: Book, Journal Article, Website, or Book Chapter. Each style handler has source-specific formatting logic — journals require volume/issue/page formatting, chapters require editor names and page ranges, websites require access dates.
Fill in the required fields (author, title, year, source/publisher). Optional fields (URL, DOI, editor, chapter) activate additional formatting when provided — DOIs are automatically formatted as hyperlinks in APA 7th, and URLs are placed after publisher info in MLA 9th.
Click Format Citation to generate the complete formatted reference plus an in-text citation example specific to that style. The output includes style-specific formatting notes explaining the logic behind each element.
Review the generated citation. Each output includes inline NOTES explaining style-specific rules (e.g., APA's DOI hyperlink requirement, MLA's access date format, IEEE's numbered bracket system) — use these as a reference when manually formatting other citations.
Copy the citation using the Copy button and paste it into your bibliography or reference manager (Zotero, Mendeley, EndNote). The plain text output requires manual formatting — italicize journal names and book titles per your style guide.
Template-based generation using client-side JavaScript — your topics and content stay on your device, no data transmitted anywhere.
Unlike many online tools that require account creation, subscriptions, or impose usage limits after a free trial, Citation Formatter is completely free with no sign-up required. Use it as often as you need without any restrictions or hidden charges. Check out our Research Paper Title Generator tool for complementary functionality.
Your files never leave your device. All processing happens locally in your browser using client-side JavaScript, which means zero data transmission to any server. This privacy-first architecture ensures your sensitive documents remain completely confidential. Learn more about Abstract Template Generator for similar privacy-focused processing.
