FAQ
Can I choose an exact KB size?
Browser compression is approximate. Use the quality and width controls, then rerun until the result is near your target.
Which output is smallest?
JPG and WebP are usually smaller than PNG for photos. PNG is better for transparent graphics but may stay large.
Does this work on mobile?
Yes. It works in modern mobile browsers, though very large photos may take longer to process.
