Frequently Asked Questions

How do I change video aspect ratio from 16:9 to 9:16?

Upload your video to the crop tool, select 9:16 as the output ratio, and the tool will show you a live preview of the center crop. When you're happy with the preview, click Process & Download to generate your cropped video. It's completely free and private.

Is my video uploaded to any server?

No — your video never leaves your device. All processing runs entirely in your browser using FFmpeg.wasm (WebAssembly). This means it's 100% private, works offline, and has no file size limits beyond your device's memory.

What video formats are supported?

The tool supports MP4, WebM, MOV, and AVI input formats. Regardless of the input format, the output is always an MP4 file encoded with H.264 for maximum compatibility across all devices and platforms.

Can I use this to crop videos for Instagram Reels or TikTok?

Absolutely! Select the 9:16 (Reels / Shorts) output ratio. The tool will automatically calculate the perfect center crop, keeping the most important part of your horizontal video. The output works great on Instagram Reels, TikTok, YouTube Shorts, and Snapchat.
