Why convert WBMP to HDR?

Storage costs and load times add up. Converting WBMP files to HDR is a small step with a measurable payoff in High dynamic range photography. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. The technical reasoning aside, the real-world result is fewer format-related issues.

This format requires a WebAssembly decoder — allow a moment for library loading
