About HEIC to AVIF Conversion
This free online converter transforms HEIC images into AVIF format directly in your browser. HEIC is the high-efficiency photo format used by Apple devices, while AVIF is the next-generation AV1-based format. Whether you need broader compatibility, smaller file sizes, or different editing capabilities, switching from HEIC to AVIF takes just a few seconds and requires no software installation.
Transparency is fully preserved during this conversion. The alpha channel in your HEIC image carries over to the AVIF output intact, so transparent backgrounds stay transparent and no edge detail is lost. The AVIF output uses efficient lossy compression, and a quality slider lets you balance file size against visual fidelity, defaulting to a value that suits the vast majority of images.
This conversion is popular with people who work with photos taken on iPhone and iPad, as well as anyone preparing images for performance-focused web delivery where bandwidth matters most. HEIC files will not open in most Windows apps, browsers, and web platforms, so moving to AVIF is a sensible, practical step. The result is a clean file that is ready to share, upload, publish, or edit further in your favorite tools.
Your privacy is protected throughout the entire process. Conversion happens entirely inside your browser, so your files never leave your device and are never uploaded to any server. The tool is completely free, handles multiple files at once, and works on any device with a modern browser, making it simple to convert HEIC to AVIF whenever you need to.
