FAQ
Is aspect ratio preserved?+
Yes — original ratio is kept by default, scaling one dimension. 16:9 stays 16:9 after conversion.
Which resolution should I pick?+
YouTube 1080p, KakaoTalk/Instagram 720p, data-saver videos 480p, mobile preview 360p. 4K is for large screens or editing sources.
Does upscaling improve quality?+
No. Going higher than the original just blurs pixels. Don't upscale beyond source. For real upscaling, you need AI tools.
Does file size shrink too?+
1080p → 720p typically cuts size by half or more. For aggressive reduction, chain with [Video Compress].
Is the audio preserved?+
Audio tracks are kept unchanged.
Does it take long?+
Re-encoding takes 1~2x the video length. Downsizing 4K to 720p takes longer due to more pixels.
