The uploaded file format is already matching the requested conversion format. Compression will still apply.
WebP compression preserves alpha transparency channel presets. Converting transparent PNGs to JPEGs will discard transparency backgrounds.

Example workflow
- Input Sample
- 1600 × 1200 pixels at 50%

Limits and Considerations
- Percentage refers to width and height, not file size. Rounding can affect dimensions by a pixel.
