Why convert HDR to HEIF?
Because HDR files use lossless compression and 32-bit float, they are not ideal for Apple devices — efficient storage. Converting them to HEIF (lossy, 10-bit HDR) 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. This is one of those changes that pays for itself almost immediately.
