Supports: BMP
Conversion re-encodes pixels: EXIF metadata and color profiles are not carried over, EXIF rotation is applied, and animated GIF, WebP, and AVIF inputs keep only their first frame (flagged on the result). Files are checked by their actual bytes, not just the extension. A corrupt or mislabeled file fails its row without killing the batch.
ResamplerVendored Squoosh resampler. Pixels skip the canvas→PNG round-trip and go straight into the encoder.
Images scale down to fit inside the box while keeping their aspect ratio; images already inside it are left unchanged (unless upscaling is on).
