AP composition-title capitalization
This option is for composition titles, including books and films. Capitalize the first and last words and principal words. Inside the title, lowercase articles and prepositions or conjunctions of three letters or fewer. Longer prepositions and conjunctions take capitals.
| Original | Result | Why |
|---|---|---|
a journey with friends | A Journey With Friends | Four-letter prepositions take capitals |
a guide for the reader | A Guide for the Reader | Short connecting words stay lowercase inside a title |
what we are looking for | What We Are Looking For | The final word takes a capital |
learning if practice helps | Learning if Practice Helps | A short conjunction inside a title stays lowercase |

AP title case is not a universal headline format
Check your publication’s headline policy. A news headline or interface heading may use sentence case instead of composition-title capitalization. Use sentence case when that is what your editor requests. The tool does not add quotation marks or decide how a work should be cited.
AP versus APA and Chicago
AP and APA look similar for many titles, but the last word can differ: AP produces What We Are Looking For; APA produces What We Are Looking for. For a comparison of this specific word, read is “for” capitalized in a title?
Length thresholds differ too. A four-letter preposition such as “with” takes a capital in AP but stays lowercase inside a Chicago 18 title. Choose the required standard, not the output that simply looks more familiar.
What still needs editorial review?
Check unfamiliar names, compounds, and words with more than one grammatical role. The tool flags internal “to” for review because usage before a verb can differ from usage before a destination. It recognizes common patterns, not every possible phrase. You can edit the result and preserve an exact name spelling.
Questions about the AP converter
Does AP mean APA?
No. AP refers to Associated Press style; APA refers to American Psychological Association style. If your academic assignment asks for APA, use the APA title case converter.
Can I format a list of titles?
Yes. Put one title on each line. Blank lines and spacing stay in place, and you can review the combined result before copying.
Is my text sent to a server?
No. Conversion runs in your browser. Loading the page requests static website files, but your pasted text is not uploaded or saved by this tool.
