How to pronounce QOI

QOI is most commonly pronounced "koy" (/kɔɪ/). This is one of several readings in active use; the developer community hasn't converged on a single answer.

The 'Quite OK Image' format by Dominic Szablewski (phoboslab), released 2021 — a ~300-line lossless image codec. The widely-held reading is 'koy', identical to the ornamental koi fish: the official logo stylizes the Q into a fish, making the pun explicit (no formal written pronunciation note from the creator exists, so it's inferred from the logo and community usage). Rhymes with 'boy'. Despite this, many developers spell it out letter-by-letter as 'kew-oh-EYE' (Q-O-I) because it reads like a standard acronym. The sibling audio format QOA ('Quite OK Audio') follows the same koi-style joke.

Alternate readings you might hear:

• "kew oh EYE" /ˌkjuː.oʊˈaɪ/

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
