Why convert HEIC to AVIF?
AVIF can be useful when you are preparing images for modern websites, landing pages, blogs, product pages, and performance-focused projects. It can create small files with good visual quality, but AVIF is not the best choice for every situation. Many online forms and older workflows still prefer JPG or PNG, so use AVIF mainly when your website, app, or publishing workflow supports it.
Tip: AVIF is powerful, but not always smaller
AVIF is known for strong compression, but iPhone HEIC files are already highly compressed. In some cases, converting HEIC to AVIF at high quality can create a larger file. If that happens, try AVIF quality around 40 to 60, use HEIC to WebP for a more predictable modern web format, or choose HEIC to JPG when compatibility matters most.
