With the rise of short-form video, creators must adapt the same video asset for multiple aspect ratios: 16:9, 9:16, and 1:1. Are you struggling with how to batch convert your horizontal videos into vertical format? Manual cropping is time-consuming and risks ruining the main subject. Users on Quora and Reddit constantly seek a simple, lossless batch conversion tool.

It offers one-click preset conversions and supports intelligent cropping and padding modes, ensuring your videos look their best on any platform.

Step 2: Select Aspect Ratio

Choose from a variety of preset aspect ratios (e.g., 1:1 Square) or enter a Custom ratio to fit your specific needs.

Step 3: Mirror Flip (Optional)

If needed, you can toggle the Horizontal Flip option. This mirrors your video, helping the processed version look distinct from the original footage.

Step 4: Set Fill Mode

Customize how the "empty space" is filled if your video doesn't perfectly fit the new ratio. You have three options:

Solid Color: Choose a custom background color and adjust its opacity.
