Frequently Asked Questions

Is my video uploaded to a server when I crop it?

No. Clipiv processes your video entirely in your browser. Your files never leave your device. The crop operation runs locally — no upload, no server, no data stored.

What aspect ratio presets are available?

You can choose from Free (fully custom), 1:1 (square), 9:16 (portrait/TikTok/Reels), 16:9 (landscape/widescreen), 4:5 (portrait Instagram), and 4:3 (classic TV/iPad). When a preset is selected, changing width or height automatically adjusts the other dimension to maintain the ratio.

What video formats can I crop?

MP4, WebM, MOV, AVI, and MKV files are supported. The output is always an MP4 file encoded with H.264 for maximum compatibility. After cropping, you can use the Video Compressor to further reduce the file size.
