## Appearance

### Theme

Light and dark are both first-class. System follows your operating system and switches with it.
SystemLightDark

### Contrast

The default palette keeps the vivid reference colors. Enhanced contrast uses darker brand and card fills so small white text meets WCAG AA.
Enhanced contrastDarker brand red, deeper colored cards, ink badges on colored surfaces.

## Image conversion

Choose which converter writes each format. Automatic is the benchmark-recommended default.

### Preferred encoder
PNGJPGWEBPAVIFJXLWP2Only option: SquooshQOIBMPOnly option: the app's internal BMP encoderTIFFOnly option: UTIF2, a TIFF encoderICOOnly option: the app's internal ICO writerGIFOnly option: gifenc, a GIF encoder

Pinned on this format only. The convert pages keep their own single all-formats switch.

### Preferred decoder

Pinned on this format only. The convert pages keep their own single all-formats switch.

## Video and audio codecs

Pick which encoder each format tries first when a run uses the FFmpeg compatibility core. A choice only reorders what gets tried; formats the core cannot write still refuse honestly.

Pinned per codec. Nothing is downloaded, and every pick still waits for the core's own capability report.
