为什么要转换
Why convert ORF to BMP
02
Broader cross-platform support
BMP is accepted by a wider range of image viewers, editors, and content systems than ORF. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Portable, predictable file format
BMP is well documented and decodable by long-lived tooling, which matters for archives, deliverables, and any file that needs to outlive the software that created it.
