A Creative Commons search engine, run as a WordPress Foundation project, indexing over 800 million openly-licensed images and audio tracks from sources like the Smithsonian and NASA.
Its value is aggregation at massive scale: one search box spanning hundreds of separate open-content repositories instead of visiting each individually.
Fits broad subject searches where you want to cast a wide net across many open collections at once.
License terms vary work by work, from CC0 through CC BY-SA, and Openverse itself warns it cannot guarantee license accuracy, so double-check the specific license shown per result.
An extensive library of free stock photos, images, and audio.
