Frequently Asked Questions

Why convert HEIC to AVIF?

HEIC is what an iPhone saves by default, and almost no browser will display it, so a HEIC photo on a website is effectively invisible. AVIF is a modern web format supported by Chrome, Firefox, Safari and Edge, and it is far more efficient than JPEG. Converting HEIC to AVIF keeps the small file sizes you had on the phone while making the photo usable on the open web.

How much smaller is AVIF than JPEG?

Typically around half the size at the same perceived quality, and sometimes better on photographs with large smooth areas such as skies. The saving comes from AVIF being built on modern video compression, which has had two decades of development since JPEG. For a page carrying a dozen photos, that difference is the gap between a fast load and a slow one.

Is it free to use?

Yes, it is free to use online, with no watermark and nothing to install. Upload the HEIC file and download the AVIF. Doing it on a phone usually means changing the camera setting, retaking the shot or hunting for an app, and on a desktop many image editors still refuse to open HEIC at all without an extra codec installed.

Will I lose quality?

Both HEIC and AVIF are lossy formats, so a conversion re-encodes the picture, but AVIF is efficient enough that the difference is not visible at sensible settings. Convert once from the original HEIC rather than from a JPEG you made earlier, because every extra generation of lossy compression costs real detail that nothing can recover later.

Can developers convert HEIC automatically?

Yes. Cloudinary accepts HEIC on upload and can deliver AVIF, WebP or JPEG depending on what the requesting browser supports, all from one stored original. That is the practical answer for any app taking photos straight from phones, since you never have to care what format the user’s camera decided to save.
