Why convert HEIF to DIB?

Want faster load times and lower bandwidth costs? Switch from HEIF to DIB. The difference is dramatic: lossy vs uncompressed, 10-bit HDR vs 24-bit. 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 conversion itself takes seconds — the benefits last much longer.
