Why convert HEIC to AVIF?
Introduced in 2017 by Apple / MPEG, HEIC was great for its time. But AVIF (created in 2019 by Alliance for Open Media) offers lossy/lossless compression and 12-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.
