Compress Video — soalan lazim

Is my video uploaded?+

No. The video is decoded and re-encoded entirely in your browser with the WebCodecs API — nothing is sent to a server.

How much smaller will it be?+

It depends on the source. A phone clip recorded at a high bitrate often drops 40–70% on the Balanced setting; dropping the resolution to 720p or 480p shrinks it much further. The tool shows the before/after size.

Why does it take a while?+

Re-encoding decodes every frame and encodes it again. It's faster than real time on most machines, but a long 4K clip can still take a few minutes. Lowering the resolution speeds it up a lot.

Which browsers work?+

Chrome, Edge and Safari 17+ have full WebCodecs video encoding. Firefox support is newer and partial; the tool tells you if your browser can't do it.

Adakah anda memuat naik fail saya ke pelayan?+

Tidak — setiap alat di sini memproses fail anda sepenuhnya pada peranti anda, dan tiada apa dimuat naik ke pelayan. Satu-satunya pengecualian ialah alat AI, yang menghantar teks yang diekstrak (bukan fail) ke Claude untuk melakukan kerjanya.

Adakah terdapat had saiz fail?+

Kami tidak mengenakan had buatan, tetapi kerana pemprosesan berlaku dalam pelayar anda, fail yang sangat besar (500+ MB atau 1,000+ muka surat) dihadkan oleh memori peranti anda, bukan oleh kami.
