Why convert HEIC to AVIF?

iPhone photos, next-gen web format

Both HEIC and AVIF descend from modern video codecs and compress extremely well, but HEIC rarely displays on the web while AVIF is supported by every current browser. Converting HEIC to AVIF lets you publish iPhone photos online at the smallest possible size, which is excellent for image-heavy pages where load time matters.

Maximum compression, kept private

AVIF typically produces the smallest files of any mainstream web format at a given quality, so it is the best target when performance is the priority. Picovert decodes HEIC and encodes AVIF entirely in your browser with no upload. AVIF encoding is heavier, so large photos can take a little longer; for the widest compatibility with older tools, convert HEIC to JPG or WebP instead.

HEIC to AVIF — FAQ

Why convert HEIC to AVIF?+

AVIF displays on the modern web (HEIC usually does not) and offers top-tier compression, so it is ideal for publishing iPhone photos at the smallest size.

Is AVIF smaller than HEIC?+

They are both very efficient and similar in size; the key gain is that AVIF works on the web everywhere while HEIC generally needs conversion.

Does AVIF work in all browsers?+

All current major browsers support AVIF. Serve a JPG or WebP fallback for very old browsers via the picture element.

Are my photos uploaded?+

No. HEIC is decoded and converted in your browser, so your photos never leave your device.

Why is conversion slower?+

AVIF encoding is more computationally intensive, so large photos can take slightly longer to process.

What if I need wider compatibility?+

Convert HEIC to JPG for maximum compatibility, or to WebP for a balance of size and broad support.
