Batch Settings
HDR data will be tone-mapped
Your WEBM file may contain HDR (High Dynamic Range) data. PNG 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.
Converting to PNG won't restore lost quality
Your WEBM file has already undergone lossy compression. Converting to PNG preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your WEBM file may contain WebM/Matroska tags metadata. PNG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Wide color gamut → sRGB
Your WEBM file uses a wide color gamut (BT.709, BT.2020). PNG 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.
