TRANSPARENCY
What about transparent AVIF images?
JPG does not support transparent areas. If your AVIF has alpha, the transparent pixels are merged with the background color you choose — white (#FFFFFF) by default. Your JPG will always be a flat rectangular image, never see-through.
For a photo or design where transparency is not required, the default white background is fine. Change the color in the converter settings before downloading if you prefer a different look.
If you genuinely need transparent areas in the output, use the AVIF to PNG converter instead — JPG can’t keep them.
