Compress MP3 — maswali yanayoulizwa mara kwa mara

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.

Je, mnapakia faili zangu kwenye seva?+

Hapana — kila zana hapa inachakata faili zako kikamilifu kwenye kifaa chako, na hakuna kinachopakiwa kwenye seva. Tofauti pekee ni zana za AI, ambazo hutuma maandishi yaliyotolewa (si faili) kwa Claude ili kufanya kazi yake.

Je, kuna kikomo cha ukubwa wa faili?+

Hatuweki kikomo cha bandia, lakini kwa kuwa uchakataji hufanyika kwenye kivinjari chako, faili kubwa sana (zaidi ya 500MB au kurasa 1,000+) hupunguzwa na kumbukumbu ya kifaa chako, si sisi.
