Frequently asked questions
Is my video uploaded?
No. FFmpeg runs as WebAssembly inside your browser tab. Nothing leaves your device.
Why does the tool take a moment to start?
The FFmpeg engine (~30 MB) downloads once on first use and is then cached on your device for instant starts later.
Metadata rotation or re-encode?
Metadata rotation is instant and lossless but some players ignore it; re-encoding physically rotates the pixels so every player agrees.
