Translations

German French Japanese Korean Portuguese

A minimal script that converts all jpg/jpeg/png files under a directory to .avif. Uses find -print0 and read -d '' to handle filenames containing spaces.

#!/usr/bin/env bash
set -euo pipefail


while IFS= read -r -d '' file; do
  avifenc "$file" -o "${file%.*}.avif" >/dev/null 2>&1
done < <(
  find . -type f \( -name '*.jpg' -o -name '*.jpeg' -o -name '*.png' \) -print0
)

Notes

  • If a .avif file with the same name already exists, it will be overwritten
  • To see conversion logs, remove >/dev/null 2>&1
