FAQ

Soalan tentang menukar AMR kepada ALAC

Adakah penukar AMR kepada ALAC ini percuma?

Ya. Menukar AMR kepada ALAC di sini adalah percuma, tanpa akaun, tanpa tera air dan tanpa kuota harian. Kerja dilakukan pada peranti anda sendiri, jadi tiada kos pelayan yang perlu dikenakan kepada anda.

Adakah fail AMR saya dimuat naik ke mana-mana?

For browser-based pairs, your file is read locally and converted by ffmpeg in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.

Adakah had saiz fail untuk AMR kepada ALAC?

There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.

Adakah menukar AMR kepada ALAC mengurangkan kualiti?

Nothing is intentionally discarded in this step, because ALAC is lossless. A AMR file encoded with lossy settings stays lossy, so missing detail is not recovered.

Bolehkah saya menukar beberapa fail AMR kepada ALAC serentak?

Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.

Adakah AMR kepada ALAC berfungsi pada telefon, Mac atau Chromebook?

Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.

Why do some conversions take longer on first run?

The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.

I converted a file and the output is blank or unusable. What should I check?

Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
