Frequently Asked Questions

How accurate is the prediction?
Within ±30% for photos. Illustrations and flat color are harder to predict (can be much smaller). File size depends heavily on image content — complex scenes = larger files than simple ones at same settings.
Which format to pick?
Photos: AVIF (best, new), WebP (near-universal), JPEG (fallback). Illustrations with transparency: WebP or PNG. Icons/simple graphics: SVG if possible. Animations: WebP > GIF.

Why Use Image File Size Estimator?

You should try Image File Size Estimator for a quick, private way to predict file size before export. Processing happens in your browser and files are never uploaded; the few tools that need an outside service say so on the page.

On the other hand, dedicated APIs or desktop tools suit batch processing better. They also handle server-side automation. For everyday tasks, browser tools offer the best speed, privacy, and convenience.
