Transparency will be lost
AVIF supports transparency, but JPG does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
HDR data will be tone-mapped
Your AVIF file may contain HDR (High Dynamic Range) data. JPG only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Animation frames will be lost
AVIF supports animation, but JPG does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
What compression artifacts to expect
JPG lossy compression can produce blockiness and mosquito noise around sharp edges. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
