JP2 Converter
Convert JPEG 2000 (JP2/J2K) to JPG — prefers native decoding, falls back to WASM if needed.
⚠️ JPEG 2000 Native browser support is poor: only Safari supports it fully，Chrome/Edge/Firefox Not supported by default.
This tool tries native decoding first, then falls back to the openjpeg.js WASM decoder (about 2MB on first use).
If it still fails, use XnView / IrfanView to convert.
