About the formats
HEIC
High Efficiency Image Container
HEIC is the format iPhones and iPads save photos in by default. It takes roughly half the space of JPG at the same quality, but Windows, websites and upload forms often cannot open it.
AVIF
AV1 Image File Format
AVIF is a next-generation image format built on the AV1 video codec. It produces files smaller still than WebP at the same quality and supports transparency and HDR.
Frequently asked questions
Is converting HEIC to AVIF free?
Yes, completely free. No account, no daily limit, no watermark and no queue.
Does it work on a phone?
Yes. It works on iPhone, iPad and Android, with no app to install.
Is there a file size limit?
There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
