Why convert HDR to PDF?
Because HDR files use lossless compression and 32-bit float, they are not ideal for Documents and print-ready files. Converting them to PDF (mixed, 32-bit) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
