You can upload JPEG, PNG, WebP, or GIF. The output can be saved as JPEG, PNG, or WebP depending on your preference.
The 'Lock aspect ratio' toggle is enabled by default. When on, changing the width automatically recalculates the height to preserve proportions.
Quality applies to lossy formats (JPEG, WebP). Lower values produce smaller file sizes with some loss of sharpness. 80–95% is usually a good balance.
