JXL
JPEG XLFormat paling mengagumkan secara teknikal dalam kumpulan ini: pemampatan lebih baik daripada AVIF, penyahkodan progresif, dan pengekodan semula JPEG lossless yang mengecilkan foto sedia ada ~20% tanpa kehilangan kualiti. Penerimaan pelayar telah perlahan dan berpolitik.

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

Adakah fail PPM saya dimuat naik ke mana-mana?

Adakah had saiz fail untuk PPM kepada JXL?
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 PPM kepada JXL mengurangkan kualiti?
It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for JXL, so you can usually increase quality if this file is your final version.
Bolehkah saya menukar beberapa fail PPM kepada JXL 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 PPM kepada JXL 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.
