Batch Settings
HDR data will be tone-mapped
Your JXL file may contain HDR (High Dynamic Range) data. WEBP only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Wide color gamut → sRGB
Your JXL file uses a wide color gamut (sRGB, Display P3, BT.2020 wide gamut). WEBP uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.
Color depth reduction: 32-bit → 24-bit
JXL stores up to 32 bits per channel, but WEBP supports only 24 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
