In latest 4.6, I’ve been able to set it through breakpoints config in ./config/middlewares.js
module.exports = ({ env }) => ({
upload: {
config: {
breakpoints: {
// Comment or uncomment keys below to disable thumbnail creation.
// Useful when you rely on services for image resizing (ie: vercel...) and
// don't want to increase disk usage, backups..
// Caution: this applies to new uploaded images.
// xlarge: 1920,
// large: 1000,
// medium: 750,
// small: 500,
xsmall: 64
},
}
},
});
