Converting between lossless formats (PNG, BMP, TIFF) preserves perfect quality. For lossy formats like JPG and WebP, you can adjust the quality slider to control compression. Default settings prioritize visual quality.
Transparency is preserved when converting to formats that support it (PNG, WebP, TIFF, GIF). If the target format doesn't support transparency, a white background is applied.
