Convert to JPG

JPG uses DCT lossy compression and remains the de facto standard for photographic images, supported by every device and application. This group covers nine source formats: HEIC is decoded via heic-convert, SVG is rasterized at 2x density, PDF pages render at 144 DPI, and all other formats are decoded and re-encoded with Sharp.

JPG has no alpha channel, so transparent regions are flattened onto a white background. Quality is adjustable from 1 to 100 with a default of 80. EXIF metadata is stripped by default while orientation is normalized automatically, so phone photos never come out rotated.
