Rendered composition
Uses the saved merged RGB/grayscale image. Layers are not recomposited; 16-bit, CMYK and PSB are not supported.

HDR is rendered to SDR using exposure and Reinhard tone mapping.
Lossy VP8 and lossless VP8L are different coding modes. Lossless WebP preserves supported 8-bit samples, not higher-precision source values. Encoding options can also change RGB values under fully transparent pixels. Quality defaults to 80; adjust it in Advanced options. File size depends on the image and encoder.
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
