What is the 16:9 to 9:16 Video Converter?
The 16:9 to 9:16 Video Reframe tool adapts horizontal widescreen footage into smartphone-optimized vertical video formats for TikTok, Instagram Reels, and YouTube Shorts.

Everything you need to know
Will reframing decrease my video resolution?
The tool always exports a 1080x1920 MP4 at 30 frames per second. In Blurred Background mode your whole video sits in the middle at full frame width; in Smart Center Crop mode the sides are cut and the rest is scaled to fill the frame.
How long does processing take?
Processing runs on your device, so speed depends on your computer or phone. On a recent laptop a 30-second clip takes about a minute and a half; a progress bar shows the time left while you wait.
Is audio quality preserved?
Yes. AAC audio, the standard in MP4 files, is copied into the new video without re-compression. Other audio formats are converted to AAC at 192 kbps, which TikTok, Instagram and YouTube all accept.
