Compress MP3 — pertanyaan yang sering diajukan

How much smaller will it be?+

It depends on the original bitrate. Going from 320 to 128 kbps roughly halves the file; the tool shows the before/after size.

Is quality lost?+

Yes — re-encoding an MP3 at a lower bitrate discards more detail. 192 kbps is a good balance; 128 is fine for speech.

Is my file uploaded?+

No. It's decoded and re-encoded in your browser with a JavaScript LAME port.

Can I set a target size?+

Not directly here — pick the bitrate. Lower bitrate, smaller file.

Apakah file saya diunggah ke server?+

Tidak — setiap alat di sini memproses file Anda sepenuhnya di perangkat Anda, dan tidak ada yang diunggah ke server. Satu-satunya pengecualian adalah alat AI, yang mengirim teks yang diekstrak (bukan file) ke Claude untuk melakukan tugasnya.

Apakah ada batas ukuran file?+

Kami tidak menerapkan batas buatan, tetapi karena pemrosesan terjadi di browser Anda, file yang sangat besar (500+ MB atau 1.000+ halaman) dibatasi oleh memori perangkat Anda, bukan oleh kami.
