- Lossy atau lossless
- Y4M is lossless, and M4A can be either. At typical quality settings this lands on lossy and trades size for some quality loss. Keep Y4M as a source if you may need a higher-detail version later.

Soalan tentang menukar Y4M kepada M4A
Adakah penukar Y4M kepada M4A ini percuma?
Ya. Menukar Y4M kepada M4A 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 Y4M 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 Y4M kepada M4A?
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 Y4M kepada M4A mengurangkan kualiti?
It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for M4A, so you can usually increase quality if this file is your final version.
Bolehkah saya menukar beberapa fail Y4M kepada M4A 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 Y4M kepada M4A 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.
