Used by JPEG, WebP, and lossy JPEG XL. PNG is lossless.

JPEG transparency matteJPEG has no alpha channel, so transparent pixels must be flattened onto a colour.

How it works

Formats: Inputs: JPEG, PNG, WebP, AVIF, HEIC/HEIF, JPEG XL and verified DNG RAW. Outputs: JPEG, PNG, WebP and JPEG XL.
Lossless JPEG XL: Lossless mode preserves the converter’s decoded 8-bit working pixels exactly. It does not preserve the original compressed bitstream, source bit depth or private metadata.
Transparency: PNG, WebP and JPEG XL preserve alpha. JPEG flattens transparent pixels onto the selected matte colour.
Metadata and colour: EXIF orientation is applied to the pixels and EXIF/XMP/IPTC/GPS data is not intentionally copied. sRGB remains sRGB. Supported Display P3 paths preserve P3; iOS/iPadOS WebKit refuses P3 JPEG XL instead of silently converting it. DNG is developed with camera white balance into 8-bit sRGB rendered pixels. Other ICC spaces, sensor bit depth and HDR are not claimed.
Batch processing: Images are processed one at a time to keep peak memory lower, especially on phones.
