Why convert AVIF to HEIC?

Introduced in 2019 by Alliance for Open Media, AVIF was great for its time. But HEIC (created in 2017 by Apple / MPEG) offers lossy compression and 10-bit HDR – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. convert.dynamic_reason_closing.closing_3

Lossy compression introduces minor quality loss — set quality to 90%+ to minimize
