What quality setting is recommended for web images?

A quality setting between 80% and 85% provides an ideal balance, reducing file weight by up to 80% while retaining sharp visual details.

Is my image uploaded to your servers during conversion?

No. The entire rendering, compression, and file export happen locally in your browser's JavaScript engine.

How can I preview the output before saving?

The tool renders a live in-browser preview allowing you to inspect compression quality and color fidelity before clicking download.
