Why crop to 9:16?

Stories, Reels, Shorts and Status are vertical. Post a landscape video and the platforms shrink it to a thin strip with huge black bars — on a phone screen it looks tiny. Cropping to 9:16 makes your video fill the entire screen. Story Split crops from the center of the frame, which fits most phone and event footage, and then — this is the part other croppers don't do — splits the result into Story-sized parts in the same run. One pass: landscape video in, ready-to-post vertical Story parts out.

How to crop a video to 9:16 online

1. Choose your video — MP4, MOV, WEBM, MKV and more, from any phone or camera.

2. Enable 9:16 Crop — open the advanced options and toggle 📱 9:16 Crop. Tip: enable Trim too and crop only the section you actually need — it's much faster.

3. Split & save — pick your segment length (60s for Stories, 90s for WhatsApp), tap Split, and download all parts to your gallery.

What makes this cropper different

One honest note: cropping changes pixels, so unlike our lossless video splitter it has to re-encode the video track. On a computer that's quick; on a phone a long video can take a few minutes — a progress bar keeps you posted. For splitting without cropping, the video cutter stays 100% lossless and takes seconds.

Frequently asked questions

How do I crop a video to 9:16 online?

Choose your video in Story Split, open the advanced options, enable 9:16 Crop and tap Split. The result is vertical, Story-ready parts — no upload involved.

Is the video uploaded to a server?

No. Cropping runs locally in your browser via WebAssembly. Your video never leaves your device.

Does cropping reduce quality?

Cropping requires re-encoding the video track, so it isn't bit-identical like pure splitting — but audio is copied untouched and the settings keep the result visually close to the original.

How long does it take?

On desktop: fast. On phones: up to several minutes for long videos, with a live progress bar. Tip: trim to the section you need first.

Which part of the frame is kept?

The center — right for most footage. If your subject is off-center, trim to the relevant section and check the preview before posting.
