Artsonia gives teachers and parents the ability to display student artwork for free on the website, which can then be purchased by others on items such as T-shirts and mugs. Twenty percent of all sales go towards art programs at participating schools, according to Artsonia. Additionally, to protect student's privacy, merchandise purchases can only be made by parents and teachers, or by those individuals who have been given explicit permission.
The children artists retain copyright to their artwork, however, submitting artwork requires accepting Artsonia's licensing terms for display and reproduction on merchandise. The site protects student identities by listing everyone under screen names, usually formed by the student's first name and a number - last names are not posted. Due to the age of users, Artsonia does not allow any artworks with nudity or violent subject matter.
Teachers or parents register students using the online sign-up form before uploading artwork. Artsonia recommends high-resolution scans or photographs of artwork for higher print quality. The site claims to be a better system than most school websites due to its ease of uploading new works, commenting system and unique Web address for each student, which makes for easy sharing. Artsonia also allows friends and relatives to join fan clubs for each student, and sends them updates when new work is posted.
