What is AVIF and Why Convert It to JPG or PNG?
AVIF (AV1 Image File Format) is an open, royalty-free image specification developed by the Alliance for Open Media (AOMedia). Derived from the AV1 video codec, AVIF offers exceptional compression efficiency, often producing files 50% smaller than JPEG and 20% smaller than WebP at identical visual fidelity. Furthermore, AVIF supports High Dynamic Range (HDR), 10-bit and 12-bit color depths, and alpha channel transparency.
However, many desktop graphics programs (older Photoshop versions, CorelDRAW), office suites (Microsoft Office, LibreOffice), content management systems, print labs, and social platforms still cannot open or import AVIF files. Converting AVIF to universal JPG or lossless PNG ensures your images open effortlessly everywhere.
Handling Alpha Transparency When Converting AVIF
AVIF supports full 8-bit and 10-bit alpha channels for transparent graphics and logos. When converting a transparent AVIF:
- Converting to PNG: CoreFormat retains the complete 32-bit RGBA alpha channel. Transparent backgrounds remain fully transparent.
- Converting to JPG: Because the standard JPEG format does not support transparency, CoreFormat automatically fills transparent areas with your chosen matte color (Pure White, Black, or Light Gray) to prevent dark artifacts or corrupted backgrounds.

Frequently Asked Questions
Why can't I open AVIF files in Photoshop or Windows Photo Viewer?
AVIF is a newer image format that requires specific AV1 codec decoders. Older versions of Adobe Photoshop, Windows Photo Viewer, and desktop office applications lack native AVIF codecs. Converting them to JPG or PNG makes them immediately compatible with all software.
Does converting AVIF to JPG reduce image quality?
At our recommended 90% quality setting, JPEG compression retains crisp details and vibrant colors while making the file compatible across all devices and operating systems.
Are my personal files uploaded to any external server?
No. CoreFormat decodes AVIF files natively inside your browser memory using HTML5 Canvas and browser APIs. Your files never leave your device.
Can I convert transparent AVIF graphics to transparent PNGs?
Yes. Simply choose PNG as your target format, and CoreFormat will preserve the transparent alpha channel without alteration.
