If I do:

mkdir -p out_sharp_webp
time sharp --effort 4 -q 100 --format webp -i 'out_ce_png/*.png' -o out_sharp_webp/

It outputs:

out_sharp_webp/CP-0_0.webp
...

identify out_sharp_webp/CP-0_0.webp
out_sharp_webp/CP-0_0.webp WEBP 2576x1934 2576x1934+0+0 8-bit sRGB 579228B 0.000u 0:00.000

Correct.

Now if I do:

mkdir -p out_sharp_avif
time sharp --effort 4 -q 100 --format avif -i 'out_ce_png/*.png' -o out_sharp_avif/

I got:

out_sharp_avif/CP-0_0.png
...

PNG? But it's not PNG!

identify out_sharp_avif/CP-0_0.png
identify-im6.q16: improper image header `out_sharp_avif/CP-0_0.png' @ error/png.c/ReadPNGImage/4092.

I know it's avif but it's not getting the right extension.

Thanks for reporting - turns out this is a bug specific to HEIF files.
