Why convert PNG to HEIF?

Storage costs and load times add up. Converting PNG files to HEIF is a small step with a measurable payoff in Apple devices — efficient storage. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. For most practical purposes, HEIF simply removes a recurring headache.

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