💡 Cara pakai

  1. Simpan script:

    nano convert_all_to_webp.sh

    (paste isi di atas, lalu CTRL+O, ENTER, CTRL+X)

  2. Jadikan executable:

    chmod +x convert_all_to_webp.sh

  3. Jalankan sesuai kebutuhan:

✅ Default (folder public, quality 25)

./convert_all_to_webp.sh

🎯 Atur kualitas dan target folder

./convert_all_to_webp.sh --dir public/meme --quality 30

🧹 Sekalian hapus file asli setelah konversi

./convert_all_to_webp.sh --delete-original

🧠 Bantuan

./convert_all_to_webp.sh --help

🔍 Opsional: Logging hasil

Kalau mau menyimpan daftar file sukses/gagal ke log:
tambahkan setelah echo terakhir:

) | tee convert.log

Jadi line terakhir jadi:

done | tee convert.log
