FAQ

Maswali kuhusu kubadilisha M4B kuwa ALAC

Je, kibadilishaji hiki cha M4B kuwa ALAC ni bure?

Ndiyo. Kubadilisha M4B kuwa ALAC hapa ni bure, bila akaunti, bila alama ya maji na bila kikomo cha kila siku. Kazi hufanyika kwenye kifaa chako mwenyewe, kwa hivyo hakuna gharama ya seva ya kukuhamishia.

Je, faili yangu ya M4B inapakiwa mahali popote?

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.

Je, kuna kikomo cha ukubwa wa faili kwa M4B kuwa 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.

Je, kubadilisha M4B kuwa ALAC kunapunguza ubora?

Nothing is intentionally discarded in this step, because ALAC is lossless. A M4B file encoded with lossy settings stays lossy, so missing detail is not recovered.

Je, naweza kubadilisha faili kadhaa za M4B kuwa ALAC kwa wakati mmoja?

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.

Je, M4B kuwa ALAC inafanya kazi kwenye simu, Mac au 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.
