Pereduksi Ukuran ZIP - Kapan Kompresi ZIP Benar-benar Mengecilkan Arsip Anda

"Pereduksi ukuran ZIP" adalah alur kerja mengambil folder file dan menulisnya ke dalam satu file .zip - arsipnya lebih kecil dari jumlah input hanya ketika file-file itu dapat dikompresi (teks polos, kode sumber, log, CSV, JSON, gambar tidak terkompresi). Format yang sudah terkompresi seperti JPG, MP4, MP3, dan PDF biasanya tumbuh beberapa persen karena overhead pengemasan ZIP.

Untuk penghematan nyata, kelompokkan file yang dapat dikompresi (log, CSV, JSON, kode sumber) dan biarkan pereduksi membungkusnya ke dalam satu arsip. Tangani media secara terpisah - ubah ukuran JPG atau MP4 terlebih dahulu dengan kompresor format khusus, lalu zip output yang dioptimalkan.
