Example

Choose a 2400 × 1600 JPEG, set Width to 1200 and Quality to 80%, then choose Create result. The result is a 1200 × 800 JPEG. Compare the actual file sizes before downloading.

Keep in mind

Aspect ratio is preserved. Images are not enlarged. PNG preserves transparency. Quality does not apply to PNG. Changing the image or its settings clears the previous download so the saved file always matches your current edits. File size can increase; compare the actual result before choosing which version to keep. Exports a still image. Animation is not preserved; SVG is converted to pixels.
