Online course image optimization tips

Use these before you upload or share the page.

Most course platforms cap image uploads at 1–5MB — compressing to under 500KB ensures fast page loads even on slow connections.

Use JPEG for photos and WebP for diagrams and UI screenshots — both load fast and look sharp on retina screens.

Batch-compress your entire course image set before uploading — it takes minutes and saves students hours of buffering.
